Spectra Fuel Tanks....

[ProSwede]

Rockauto have a another part number for this tank now...#GM32BFI instead of #GM32AFI....I wondered if this meant that the new design has been released to the market so I mailed Spectra about this and got this answer:

(My question)
Hello, I wonder if your updated version of your fuel injection fuel tank for 1969 Chevrolet Camaro is yet released? If not, when will it be released to the market?

Regards, Andreas



(Their answer)
Hello Andreas

Yes the GM32BFI is now available

that doesn't make sence....the #GM32BFI is for 69 Camaro, with tube...and the #GM32AFI is for 67-68 Camaro. part numbers where always there. nothing new?

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.

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.

I'm interested, whats the overall length/height? post or pm me any other details if you'd like please! thanks

I just measured a spare 4th gen unit I have. It's spring loaded, to rest on the bottom. 10.5" maximum height (in tank). Minimum compressed installed height is 9.25". 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.

[b25]

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]

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

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
