Spectra Fuel Tanks....

[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?

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.

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.

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

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.

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

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

Rockauto.

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.

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.

I'll be mini-tubbing the car, but only running a 19x10" wheel for now, will this tank work???

The Tank



The pump/sending unit:

The pump says:

SFP003
V:179

Owned!

Now if they would just make FI tanks for X body cars...

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?

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

It was over $450.. I think $480something..

Look around someone is offering X body for less than a grand. I swear I've seen them on here. I have an x body so I noticed.

Could this be the pump?

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...

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

[Steve1968LS2]

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?

[BonzoHansen]

Hey, related question someone just asked on NastyZ, I thought one of you guys might be able to chime in here or there...

Can anyone post up wiring info/diagram for this setup?

thanks-
