Spectra Fuel Tanks....

[trapin]

Alright....about a few months ago I heard a rumor that there was a company called Spectra that builds aftermarket fuel tanks with built-in fuel pumps specifically for LSX conversions into classic cars for around $600-$700 a pop.

What I want to know is; how do I contact them? Anyone have a website URL? Anyone have one of these tanks? And lastly...is there any truth to all this?

Thank you gentlemen.

[LSXfan]

yes....

http://www.rockauto.com/

look up your vehicle type/year/model, then under fuel tank EFI..the one they have listed will be a Spectre unit

You people are beautiful.

Have I ever told you that?

[MuscleRodz]

Tony, Spectra does not sell direct. We sell their tanks $595 plus shipping. I have sold quite a few of them, very nice piece. If not minitubbing, it is the only EFI tank I would use or recommend.

[trapin]

Mike...what part number do you have for that tank? Is it GM32AFI?

[MuscleRodz]

yes that number is correct and have several at our suppliers wharehouse ready to ship.

[CarlC]

What kind of baffling and/or anti-fuel starvation systems do these tanks have?

[Damn True]

It's just a metal tank right....not a cell?

[trapin]

According to Phil at BRP.....

"This is a stock style tank with a factory look built to EFI spec with use of the factory gas cap and filler neck. This is not a modified tank and comes EFI from the manufacturing facility. The tank comes with baffling and sump to stop fuel slosh and prepped for the EFI and features an in tank electric fuel pump that produces 85-115 PSI at 50-60 gallons per hour. This is the perfect tank for a LS conversion and keeps the original look of the factory tank. The fuel tank is designed to work off any 12 volt system, with a sending unit is designed for any factory applications."

I would still call Spectra to verify this information.

Frank Serafine first told me about these tanks. I'm surprised they're not gettin' more buzz on here what with all the other aftermarket tanks starting at over a grand.

[Steve1968LS2]

Hmm.. maybe I should run this on the Track Rat project.. to help keep costs down.

[MuscleRodz]

Tanks are not baffled. They have a well in them just like new OE tanks do so the pump ALWAYS stays submerged even with low fuel levels. No starvation issues either. I have pics of the well on one of my computers somewhere. I have sold quite a few of them, no complaints.

[MuscleRodz]

Hmm.. maybe I should run this on the Track Rat project.. to help keep costs down.
Maybe something can be arranged.........

[Rick Dorion]

Hmmm. I suppose I could use one with a regulator for now in a carb application?

[MuscleRodz]

Hmmm. I suppose I could use one with a regulator for now in a carb application?I would not recommend it. Very good chance of burning up the pump depending on the regulator used. I would stick with a stock tank until ready for efi conversion. Plus stock tanks are cheap. Spectra has those too.

[tmadden]

Do they make anything for min itubbed camaros?

[BonzoHansen]

Do they make anything for min itubbed camaros?
Not that I saw.

Phil also lists one tank number for 70-81, but that cannot be correct. 70-73, 74-77, 78-81 are different tanks/necks. Spectra only lists 70-73 IIRC

[CarlC]

So is that just a small sump on the bottom of the tank? That might work for straight and normal driving but it won't keep the pump submerged if cornering hard. Current OE setups use a venturi pump and bucket reservoir to overcome low-fuel cornering starvation problems.

Current OE setups use a venturi pump and bucket reservoir to overcome low-fuel cornering starvation problems. nope, it is a bucket reservoir, pic is a little decieving. Depending on the tank, 5"-6" tall, about 8" square. Pump is from a late model Chevy truck, I don't remember which one right now. I have a tank on its way to me now. I could give some better pics of the well with dimensions once it arrives.

[Rag-Rat]

I need some persuading to talk me into one of these over a Rick's. I am going EFI and at first I wanted a stock look and did not know about these tanks. So I researched the Rick's Stainless tanks and like the way they look on cars. Does one have a benefit over the other (other than price).

[CarlC]

Thanks Mike. This has the makings of a great setup.

Unless you are mini-tubbing or need wild HP fuel requirements, or want stainless, no need to go to the extra expense.

Mine just showed up today.. GM32AFI for the Track Rat project. Looks good so far.

[Steve1968LS2]

Behold the man that turned me onto these... lol

[Steve1968LS2]

I do believe this is the pump capacity:


The tank comes with baffling and sump to stop fuel slosh and prepped for the EFI and features an in tank electric fuel pump that produces 85-115 PSI at 50-60 gallons per hour. This is the perfect tank for a LS conversion and keeps the original look of the factory tank.

Pump is the same as AC Delco EP381
with a 3 1/8" in diameter.

So, would this support your typical LS engine (ie, less than 500hp)?

Also, I'm going to pull it apart to see if a larger pump can be used.

It was just over $450... Add in the 'Vette regulator/filter (PN GF822) and you have a cost effective efi fuel system.

[MuscleRodz]

You won't be disappointed Steve. They are the best efi tank solution if you have the room for a stock tank

[BonzoHansen]

Cool, can't wait to see it.

[Steve1968LS2]

I did some noodling and it seems like it would be good up to just over 500hp with the included pump.

Anyone want to double check my calculations?

[CarlC]

That pump is likely a 190LPH. 50GPH = 190LPH.

If so, no problem for 500HP. 600 would be the upper limit. Magnuson recommended a 190LPH for mine.

From the Holley site:

HP/2 = # of fuel

50 gal * 6#/gal = 300#

300 = HP/2, HP = 600

This is likely pretty conservative.

Looking closer at the above pics, is that a hole in the bottom of the sump? Is that how the sump fills? Does the pump filter cover this hole so that it acts as a one-way valve? Slurping up the fuel from the bottom of the tank through the hole?

[MuscleRodz]

Slurping up the fuel from the bottom of the tank through the hole?The hole is how the tank self levels when not in use. The return line pumps unused fuel back into the well, and forces the excess fuel to run over the top of the well. No chance of starving the pump unless you run out of fuel. When you shut the car down, if the fuel in the well is higher than the tank, it will gradually self level with the rest of the tank.

[BonzoHansen]

So that sump is deep enough so hard cornering with 1/8-1/4 tank will not starve the engine? Or am I asking too much?

[Steve1968LS2]

You're asking too much...

;)

I'm sure there's a math equation to figure that out. I guess I will find out durring testing. Once I get the tank apart I will let you know how deep it seems.

I'm sure part of it relates to how much gas is in the tank.

Thanks Mike. How/where does fuel enter the sump? I'm missing something from the pictures.

Also, if the pump and sender assembly go into what I'm assuming is the sump area, and recirculated fuel is intended to overflow the sump during normal operation, wouldn't it give eroneous fuel level readings? OE fuel buckets have the sending unit attached outside of the bucket.

When not in use fuel enters through the weep hole you see in the bottom. Sending unit sits outside the well. Only eroneous reading you should get is the same as you would with stock tank during accel, decel, or turn

[MuscleRodz]

So that sump is deep enough so hard cornering with 1/8-1/4 tank will not starve the engine? Or am I asking too much?Well in fairly deep, and with the fuel being returned to the well, pump should stay sumberged unless tank is nearly empty and in a sustained long corner. Always a scenario where anything is possible.

Where did you get it for $450? I thought Mike said his were $595.

Rockauto.

[Steve1968LS2]

Where did you get it for $450? I thought Mike said his were $595.

Rock Auto... I don't remember the exact price but it was under $500.

It'a hard to find on that site, better to just call them. Part number is GM32AFI

I've heard they have 5% discount codes out there as well.

[MuscleRodz]

Where did you get it for $450? I thought Mike said his were $595.Rock Auto is killing me and have not sold one since the word has got around. I wasn't buying them from Rock, and they are selling them for basically what I was paying for them.

That sucks and I'm sorry about that. I would imagine they buy tanks by the truckload and get a discount.

Personally I would rather pay a bit more, get them from you, and get better customer service.

[Rag-Rat]

Nice pictures Steve. I take it that the price included the pump AND the sending unit as one piece? Does the sending unit work with the stock gauge?

[Steve1968LS2]

Includes everything you see.. it's a 0-90ohm sender from what I gather.

Could this be the pump?

http://store.getgmparts.com/fe0114.html

Lots of pumps on this site that look like the one in the tank but I would need to see the markings to tell which one this is.

Might be possible to swich out the pump for a larger GM one? Just thinking...

[MuscleRodz]

Ask Tony Whatley if he ever installed his Racetronix pump. He said he was going to install one of these.

I don't see why you couldn't.. I was more curious about the service issue (ie, direct replacement pump) and if there was a cheap GM pump with a higher output.

The Racetronix pump is nice, I wonder if they would know?

The pump is a GM truck unit, not sure which one.

[CarlC]

A Walboro 255lph should be easily adaptable. But if Spectre says it's a 190lph that would be perfect. No need to heat up the fuel more than necessary.

Perhaps Spectre would supply a replacement AC Delco number for the pump? Everyone in the AM deals with AC Delco or Federal Mogul P/N's.

The pump is numbered, there should be some way to figure out which GM pump it is.

Would be nice to know what's needed for a replacement.

Time to make nice-nice with your local AC Delco rep Steve.....

[BonzoHansen]

Nope, they won't, I have tried.

What are they suggesting for replacement parts? Are they selling pumps separately?

[dhutton]

That pump looks like the same one Rick's told me to use when my pump died. Once I got mine out it turned out I had a Walbro pump but apparently Rick's is now using the GM pumps. The pump they told me to use cross referenced to a Delphi FE0114 pump that I picked up at Oreilly's. It was from a 96 1500 pickup with a 305.

Really? I would expect a Ricks tank to have a nicer pump like a Walbro or Bosche.

This darn pump has numbers on it but I can't identify them. I guess I need to find a place that stocks them and visually compare the numbers on the casing...

Mine does have a Walbro but it sounded like they changed over to the GM pump at some point because that is what he assumed I had in mine.

I did some more digging and this is the AC Delco part number that Rick's gave me: EP381

[Turbo67camaro]

Would one of these likely fit on a '67 Camaro with DSE mini-tubs and a G-Bar?

I'm going EFI.

I have a GM NOS tank that looks like it will fit with my combo, but then again, I don't have wheels and tires yet, and don't have exhaust pieces to mock up.

[trapin]

What is a G-Bar?

If you're minus the leaf springs than yes the tank will fit. If you mini-tubbed but did the offset shackles for the leafs, then no.

I doubt I'll go wider than 315s on tires due to the $ premium required to get there for wheels, tires, narrowed tank...just another consideration for my pending wheel and tire choice.

Leave it alone. It is galvanic plated and needs nothing

If I had known about these I would have definitely gone that route, Anyone wanna buy a sumped tank with dual 10s? LOL

Galvanic plating...just how rust resistant is that, say compared to the stainless steel used in a Rick's tank?

From what I've heard, even stainless steel can rust.

https://static1.pt-content.com/images/pt/2009/02/28044ti-1.jpg

The pump/sending unit:
How about a picture of the bottom of that tank? I still dont see how that short sump area can hold enough fuel in a hard corner. If the sides of the area were tapered in or completely straight maybe but the walls taper outwards. Like someone else said GM is using a venturi can that completely covers the pump and the fuel returns to the can. With the GM setup you may lose 1/4 of the fuel on a hard corner but the tank is almost still completely covered.
I think that tank may be fine on a weekend warrior but not for track use.

From what I've heard, even stainless steel can rust.It will last for a long time. Galvanizing has good corrosion resistant properties.

Yes certain stainless can rust, but it is because of a higher percentage of iron contained in it. 400 series stainless can rust. 300 series much less prone to it.

What a nice piece. I am stoked.
Just came in. One step closer. Thanks again for this great find guys.

I am currently building a 73 Camaro and would like to purchase a complete FI tank for it. I recently called Spectra to ask a simple question but I hung up the phone still confused, can someone help answer my question below?

Rockauto only seems to have the tank for 1970 Camaro.

Here is what I found in my research www.tanks-to-pans.com (http://www.tanks-to-pans.com/)
1970 (w/o vent)= FN-GM42AFI
1970 (w/ vent) = FN-GM42CFI
1971 thru 73 = FN-GM42BFI

Here is what I find on RockAuto
1970 (w/o vent)= GM42AFI
1970 (w/ vent) = GM42CFI
1971 thru 73 = NOTHING

So... can GM42A(C)FI work for a 73??

[HOTROD99]

My tank came with no wiring instructions does anyone know which wire is for the sending unit.thanks rod

There should be three wires, Grey is for Power to the Pump, Purple for sending unit, and Black is ground. It sounds like Grey is always power to the pump.

The bottom looks no different than any other factory tank.

The sides of the "sump" (or bucket) are straight up and down. It sould work fine.

I guess we will find out when I sling it through the cones ;)

The difference is the number of vents. You can use the earlier tank with no vent if you eleiminate you emissions canister

So how does the fuel enter the sump?

Made for own. $96.00 tank from rock auto, $20.00 fuel level sender, scrap steel plate I had sitting around and a sending unit with pump from 94 LT1 I also had sitting around. Also baffled the tank.

[MuscleRodz]

So how does the fuel enter the sump?
Weep hole in the bottom allows the tank to self level. Once fired, the return fuel is dispensed back in to the well making sure the pump is submerged at all times.

About 3 hours. Could not bring myself to pay the $450-600. Some places are $1000

[Xlerator]

The difference is the number of vents. You can use the earlier tank with no vent if you eleiminate you emissions canister

Thank you Mike! How much would you be selling this tank with shipping? How close are you to Rockauto? I too would hate to not give you a chance.

[trapin]

Mike I would also like to help out a sponsor. But I'm on a budget and can't afford that amount of difference. Can you work with us?

If not I understand. I just want to make sure I come to you first.

[MuscleRodz]

Go to Rock Auto. I wish I could compete but they are buying direct and required a 300 piece buy in which eliminated me from buying direct. Thanks for at least thinking of me.

[BossaNova]

Balljoint,
Did you take any pics of the baffles inside the tank?


Made for own. $96.00 tank from rock auto, $20.00 fuel level sender, scrap steel plate I had sitting around and a sending unit with pump from 94 LT1 I also had sitting around. Also baffled the tank.

No pics, but I used a small $5.00 baking pan from walmart and welded to the bottom of the tank. Then drilled a hole on the side to allow gas in and slowly out. Pump and strainer sits in it nice. Pan is about 7 inches long X about 3 inches high. I am not trying to discourage people from buying any other product. I just wasnt born with a big trust fund and if I can save a few bucks, I will. I have more time than money.

[balljoint]

yes, slowly. Then pressurized air into the tank with soap water on the welds to find the small leaks.

Great thread.

Don't forget about the 91-96 Impala/Caprice/Roadmaster (sdn) tanks. They are plastic, big, and can fit quite a few applications.

[Karch]

If you do a search, there's a guy here that has a first gen (I think '69) Camaro that put one in with little modifications. I think he used a heat gun on one corner of the tank to massage it to fit.

My buddy has a '73 Grand Am and he said it's fitting perfectly, and my '65 GTO, while I don't have it in yet, it should fit w/o too much modification.

On mine, I am cutting out a 12"x12" section of my trunk floor and adding an access panel, which you can buy for about $15-$20, that is basically a hinged door so you can access the pump/pickup module.

I may need to raise my trunk floor a bit in the middle to clear the hump on the tank, but for what you can get a tank for at the junkyard, it does make an inexpensive alternative.

I got a spare pump/pickup module that I removed the pump from and have the option of using it to feed an external pump, whether carb or efi, though it won't be sumped (preferred).

But, these Spectra tanks are also a very nice option.

Lastly, I believe Walbro makes a 255 lph high and standard pressure pump that will fit without much trouble.

69 Chevelle tank...

[Mr Nick]

I would not recommend it. Very good chance of burning up the pump depending on the regulator used. I would stick with a stock tank until ready for efi conversion. Plus stock tanks are cheap. Spectra has those too.

What is the correct regulator that would be needed to run this with a carb?

[s4dustin]

Does anyone have the part number for the Corvette regulartor quick disconnect ? Also, where do you place the regulator? Where is the corvette regulator located?

[Mr Nick]

Possibly this? The notes even say its for an EFI pump, but running a carb.

The Aeromotive product comes with 2 different springs, so I could keep the same regulator when I do switch to EFI.

[Chevy]

FWIW,
I am running this tank and found out last weekend the limits of the baffle. With R compound tires on the autocross track you are looking at fuel starvation at anything less than 1/2 tank of gas. Above 1/2 tank if you are a smooth driver you should be OK.

Also in mine at least i have never gotten the fuel gauge to work properly, it has the problem that someone here predicted...it reports full for a very long time, presumably due to the baffle holding the fuel level indicator artificially high with the flow from the return line. At 1/2 tank of gas by volume, mine still reads ~90% full.

Still, for the price, a very nice tank and pump. I have about a 400 HP small block, pump is plenty strong enough for me.

I am thinking about putting some foam in to decrease the sloshing...any opinions?

[firstgenguy]

Well here is my experience with the spectra premium gm32afi. I bought one from RockAuto for 460.00 shipped. I scuffed and painted the tank not expecting any problems. After I installed it and put 1/2 tank of full in it I first found the fuel sender was not working. I heard the pump running but would not pressurize the fuel system. No matter what I did it would just run but would not push fuel. So I called RockAuto and the would send a replacement right away but I had to send the whole tank that I just painted back. Got my replacement within 3 days. This time I tested everything before doing any painting. Good. I again painted the tank and everything seemed fine. Car fired right up. Noticed the fuel gauge would go past the full mark when I filled up, no problem. So I went on a spring cruise and the car ran great till I ran out of fuel cause the gauge would not read below 3/4 ! Now I have to ttry to get another replacement! Anyone have sending unit problems?

[Bryce]

is the sending unit and gauge matched? for example are they both for chevys 0-90ohm? sounds like the sender is a ford.

[firstgenguy]

Falcon65, The fuel gauge is a 0-90 ohm Autometer. The fuel sender is 0-105 ohm. I did get it figured out. The problem is in the design of the tank I beleive. The in tank pump and level sender sits in a bowl that being filled with fuel returning in the same spot.

[Bryce]

im glad you got it figured out, thats is a bummer that it is designed poorly. maybe some foam will help to reduce return interference?

[notchbackgta]

Its not interference, the baffle area stays full with fuel and the float for the sender is in that area, not outside the baffle so the float is up all the time. They should have modified the sender arm so it sat outside the baffle area. Not as well designed as a GM sender from the 4th gen f-body

I got one of these Spectre tanks from Rock auto about the same time and just got it installed last week. Mine wouldnt pump fuel either, but i could hear the pump running. So i pulled the sending unit then the pump itself. I put the pump in water (to prevent a fire) and jumped wires to it (correct polarity) and low and behold it shot water about 8 inches. Next step was to check the polarity with a multimeter on the plug and sure enough, the 4 prong connector (grey) under the sending unit assy, had the wires crossed for the pump. THis caused it to spin backwards and not pump fuel. I pulled the lock out of the plug and pushed the pins out with a paper clip and corrected the polarity. Verified the sending unit polarity also. It was ok, so perhaps the person wiring these units had a bad day or few days and obviously these units arent tested before shipping. So after wasting a couple of hours troubleshooting the thing, flushing the pump and lines, the fuel pressure hit 58 psi and fired right up.
As far as your sending unit problem, pull the sending unit/pump assy and hook your meter to the sending unit wire (purple) and ground. Move the float assy up and down and measure the ohms. Also check to make sure that the float isnt obstructed in any way, it must float freely in the tank. If something is not allowing it to go down with the fuel level, it will cause the gauge to stick. This is the third component in this LS swap in a 67 Camaro that has not worked and needed modification or troubleshooting. Fun stuff...:machine:

[Mr Nick]

I'm still considering this... but would like the fuel gauge to work properly. Would drilling a few small holes on the side (near the bottom) of the fuel well/bucket help the excess fuel in the well return to the main section of the tank? Hopefully without defeating the purpose of the well, which is to keep the pickup submerged at all times.

[The T-man]

any word yet on this tanks ability to handle high G turning w/o starvation issues?

[Turbo67camaro]

any word yet on this tanks ability to handle high G turning w/o starvation issues?

User "Chevy" reported earlier on this page that you'll see fuel starvation on the track under hard driving with anything less than a half tank.

It seems like the only solutions to deal with that are fuel cells or surge tanks.

[bigblockcamino]

any word yet on this tanks ability to handle high G turning w/o starvation issues?

Tank will handle no problem. Issue is with the fuel pump. :idea: I would not drill any holes in the bucket, defeats the purpose of having it in the first place.

I bought a regular tank, cut a 4.5" hole in the top. Currently working on modifying a custom drop in surge tank using a aluminum overflow tank/venturi jet. This is the same concept the OEM' pumps use to fill the bucket up. I just hope the capacity is enough. Need a few more fitting and measurement before it done. Only downside it pump is external.

[aray327]

i'm really late to the party on this one, but i hope you guys are still looking at the thread.

i purchased the spectre tank for my 69 camaro almost a year ago. the fuel sending was no problem, fired up first time i got 12v to it. However i have always had starvation problems and have never gotten my guage to read. I have spoken to spectre a few times, and sent my guage back to autometer to have it tested. autometer assured me the guage was accurate so i call spectre again. spectre told me to exchange the tank.

i just got my new tank and still have the same issues.

Did anyone get their guage to work?

[Mr Nick]

Too bad Spectra hasn't fixed this, poor customer service. I'd get one in a heartbeat if it was a true bolt in deal.

[68zz502fi]

I bought one of these spectre tanks for my 68 camaro,It looks just like a stock tank externally except for the SAE 45 fuel inlet fitting. I have yet to install it as the car is still under construction. Im running a ZZ502/502 with Holley Projection II MPFI. do you think the existing fuel pump will suffice for this application. stock ZZ502's usually make between 510-530 HP from what I have read.


Thanks!

I hear mine spinnning, but no fuel going out of it....what a pain, so close to hearing it fire for the first time in 2 years.....any specific instructions on what color wire goes where?

[s4dustin]

Easy fix...had the fuel lines backwards...switched them and BAM, the car started for the first time since the swap! :)

[trapin]

So.....back to the gauge problem. Is anyone else having problems with their fuel gauge?

[Mr Nick]

I'm doing my fuel system this winter, I'm going to contact Spectra and see if they have an explanation/solution for this. It's just silly to put the return line into the same bucket the gauge reads from.

If it's a simple fix, I'll get one. If not, then external electric pump for me and a lost sale for Spectra.

[notchbackgta]

Actually you want the fuel return to be in the bucket. Spectra really should move the fuel level sender to the outside of the bucket. This would solve the issue for everybody

[Mr Nick]

Correct, I worded my sentence weird.

Finally something cool made in Canada other than beer!

[69cutlassrkt]

I have a spectra tank. I think I have put 3000 miles on my car since I have gotten it. I always fill my tank up when its half full cause if I turn to quickly the engine might start to die. Also the fuel gauge doesn't read right. I just reset my trip odometer every time I fill up.
Though I think for the price its worth it.

[Ishmael]

I just went to the local Car Quest for one. They couldn't get one and the person they spoke to didn't want to comment on when or even if they would be making more so I called myself. A guy I spoke to said they were "in production." Hopefully that means they will be making more. My cost is $564 Canadian and that's a jobber rate so if you can get one through Rock Auto or Muscle Rodz for less than $600, I'd say jump on it while you still can.

[Ishmael]

Spoke with spectra tech this morning. They said the starvation issue was because the pickup wasn't long enough and they've fixed the problem. Also the sending unit should read correctly now but test it first. New batch to come out by the end of the month.

I asked about that and the sending unit issue. Tech said both had been addressed but I don't see how they could if they are using a cup and no baffling or sump.

I'm going to call them again tomorrow and speak to a tech who may be able to shed a little more light on the situation... I really want to use this tank BUT I like the idea of the 4th gen LS1 Pump.

The 4th gen pump assembly is way too long to fit in stock first gen tank. I was gonna mess around with having it modded to make it work, but ran acrosss a deal on a used spectra tank and decided to buy it. I still have the 4th gen tank & pump assembly if someone wants to do some experimenting.

I just got mine (#GM32AFI) that I'm going to use in my '67 Firebird.
I could pull the pump and snap some pics if there is something specific to look for that has changed.
When I talked to Rockauto a couple weeks ago because I couldn't find it on theeir site, the guy I talked to said they were out of stock because of an issue with the supplier(that's all he knew). But told me to keep watching the site or call back, because as soon as they get more tanks, they'd show back up on the website.
I ordered Saturday and just got it yesterday.
If that helps anybody.

[MrQuick]

can you double check the ohm readings at the sender for us please?

[Rhino]

Would anyone happen to know what fuel pump is included in the tank? Is it internally/externally regulated? What kind of HP is it good to?

EDIT: I just happened to see earlier in the thread that it was determined to be a replacement for a GM truck and good up to 500-ish HP.

You'd need a 3.75" diameter hole to slide the entire basket in. I had been planning on using this unit as well, but don't know if it's worth my time. You may be able to shave 1 - 1.5" safely from the installed height.

For this unit to work you'd have to drop the floor of the tank roughly 2-3"

Can anyone who's spoken with Spectra summarize (in detail) what the problem with these tanks was determined to be (specifically with regard to the starvation issues)? I've read speculation that the fuel pump pickup might not be long enough, but nothing definitive.

I'm really hoping that a fix can be identified for those of us with the problem tanks/problem fuel pumps.

If there is no easy fix, has Spectra offered to replace tanks/pumps for those who have the problem units?

From what I have read on the camaros.net forum they replaced the baffle pan with a larger and deeper one. I somehow doubt that these tanks will be completely fixed with this change but they might be good enough for street use. If you got your tank from Rock Auto it sounds like they are replacing them under warranty if you have had it for less than one year.

Otherwise I think the only real fix for these tanks is to replace them or add a surge tank. There is no way to upgrade an older tank.

I didn't buy my tank from Rock Auto and was hoping Spectra would make it right by sending a tank direct from the MFG. Reading through the various threads it is still not terribly clear what the 'fix' is.. I guess I'll try and call Spectra myself and get the ground truth.

[Magntik]

can you double check the ohm readings at the sender for us please?

Sorry guys, I got busy with life and hope to make some progress this weekend. I'll yank the unit to get a good reading and try to shoot some pics of the inside of the tank.

I had emailed Spectra to get the range in ohms because I looking for aftermarket gauges, the response says 0 ohms empty, 105 ohms full. But I need to verify this.

I am on my second one of these tanks in 2 years with problems.
#1 Bought the GM32AFI from Rock auto for a 67 Camaro LS1 swap i did in 09. Wouldnt start, no fuel pressure, but pump was running. Took the pump assy out, did some troubleshooting, and the wiring inside the assy was all backwards, the pump and sending unit. I removed the pins from the connector to the correct positions, voila! Fuel pressure, car runs, stock gauge works. 100 miles later the pump dies, same SFP003 number etched on the pump, cant cross it. Figured out a 97 Chevy pickup Delco# EP381 from Orielly, fits and works. Put it in the car in 2009, no problems since, all stock 67 body/ suspension Camaro, LS1 with cam and T56 ran 12.20s at 117 in the 1/4 with this Delco pump. Most ppl say up to 500hp.

#2 Bought GM32BFI for LS2 swap in a 69 camaro a few months ago. Rock auto quit carrying them because they say spectra always has them on backorder, so we found another retailer had one in stock. Installed, car ran great, (wiring correct inside this time) no starvation all the way until the tank was empty so thats good. 100 miles later, the pump died yesterday. Same SFP003 part# on the pump. Called Spectra, they said there were problems a few years ago with cavitation/starvation in these tanks, so they have since improved the baffle/pan the pump assy sits in. The tech guy at Spectra says they use a delco pump and havent heard of any problems like mine. I put the new pump (numbers stamped not laser etched) and it runs great again.
I am using the hotwire auto harness on both cars, which uses a bosch style relay from the pcm to turn the pump on, checked that to 12+ volts to the pump everytime.
There are other options on the pump replacement if you cant find the delco. Check Orielly or Rock auto for EP381 or a 97 Chevy 2500 suburban with a 454. Oriellys price is about $50 more for the same pumps. Hope this saves someone some time and headache. :)

Wow, I had almost forgotten about this one.

So, I'm running Dakota Digital VHX gauges and pulled the pump assembly. Sending unit ohms' to 114.5 full and 0.8 empty. DD has a custom setting so I programed the gauge to the sending unit. So I should be dead on as far as fuel level.

I have about 500 miles on the set up and no issues yet. Mostly hard street driving and some smokey burn-outs.
The car was on the dyno last week and the guy say it ran great and maintained around 55 psi the whole time. And he ran most of the gas out of it during the two days he had it. Gauge said 10% (DD has a LCD read out that shows all the readings) and I drove it hard about 3 more miles to the gas station. Put about 15 gallons in it so there was 3 or so left.
No problems and this is the tank I bought late year.

Curious to see if my luck holds on power tour and Good-Guys Autocrosses

[Custom Muscle Cars]

Magntik, I am also running the DD VHX gauges in this customers 69. I love functionality and adjustablility of these gauges and how all the indicator lights and message centers are integrated into them. I ran this car past 10% (0% lol)at the shop before i could get to the gas station and it still ran fine. I pulled and checked mine to ensure it was wired correctly and the sending unit worked. The sending unit from Spectra was supposed to be 90 full and 0 empty, mine was around 110 full and 0 empty. DD actually shows the current measurement in ohms in the fuel gauge setup. Perhaps my fuel pumps were flukes, so hopefully yours and everyone elses will continue to work.

Has anyone has any luck lately with a tank for a 2nd gen from Spectra. I am going to replace my tank next month and wonder if its really necessary to step up to a vaporworx or someting similar? I am at about 600hp at the crank,and running EZ EFI with their pump kit. I believe the tank I want is the gm42bfi,or the gm42afi.

Done,thank you. Still interested in info on the Spectra tank or a reasonable facsimile

Just seeing if anyone has anything to add?

[k7king]

200 mils and my fuel pump went out at the Columbus goodguys car show.I never had the tank under 1/2 full. THANKS TO RICKS TANKS for giving me a pump for a tank I didn't buy from them. Guess what I'm doing now......ripping this POS tank out and ordering a Ricks. Don't waste your money on a Spectra

[rossmacd]

I don't see anything listed for Fords... any chance there's a secret part number for a 67 mustang? I'd love a rick's but can't bring myself to spend 1200 on a tank when I don't make enough power to command that kind of $$$.

[CarlC]

It's not power that commands the need, it's fuel slosh control. Any EFI engine, wether it's 100 or 1000hp, will suffer from fuel starvation unless precautions are made to control fuel slosh.

Ibelive that Rick's uses better pumps designed for higher hp applications, and that is where some of the added cost comes from. At least gnats what I'm assuming. I'm sure the stainless steel is a part t too. My engine has been doing just fine with its stock tank and external pump for for years now, but I'm still thinking about upgrading.

Mine seems fine with the EZ supplied pump so far,so I am leaning towards a more cost effective fix. What have you done to control slosh? I am in trouble at anything below about 1/2 tank.

I have no slosh control; it's simply a stock tank with an external pump. Once I get below a quarter tank, the pump starts to make a bit of noise. It was really loud with the a1000!

[rohrt]

Wow I see they are priced at $360 on Amazon. Out of stock of course :(

Shoot. At that price I'll stick a camaro trunk floor in my mustang.

Carl,
Has anyone thought about using a pressurized bladder to always keep the pick up submerged? I picture a bladder surrounding the fuel with a certain amount of pressure in it so that as you use up fuel, the bladder takes up the air space(eliminating the air pocket) and the fuel pickup would always have fuel surrounding it no matter the level in the tank. I was thinking about this the other day...thinking about a cold water storage tank for a house that has a gas charged bladder...or is that a dumb idea?

[CarlC]

The problem with any type of fuel bladder is that it needs to be periodically replaced, especially if it's collapsible (lots of sharp bends.) By the time you get done making something like that, you might as well get it done with a fuel module and not have to deal with associated bladder problems, labor, etc.

Water, that's a whole different gig.

^^makes sense...just a passing thought. LOL
