Fuel Pump

[Prospeeder]

Hey i work at napa now, and i get a big discount on parts, well, I am lookin for a fuel pump, and i put in that its the vin V and turbo and all that, and the pumps it list cross over to every freakin gm you can think of, including the corvette, well is this the correct one? I can find out every pump avalibles flow rates and what not, what is our stock pumps output?

[TGP Nick]

IIRC, it uses the same fuel pump as the corvette.  Part # EP375.

ya the Vette one works, walbro 255 or somethin like that I believe it is.

I've got the vette on in my TGP, works fine, not sure what the flow rate is though.  WIll be putting the Walbro 255 in the TSTE when I get back home its the best out there for fuel pumps (for our application) see the write up Kenny did on this mod:

If you put that 255 in there you might want to have the car tuned, it will run but it is going to make things rich especially under WOT....Just and FYI

alright, thanks, it has a few listed, one says its rated 28psi, the other 65, so im guessin its the 65. Also whats our wiring setup, WEK, WEE, or WEA or what the hell ever they are, lol. Im able to get with my napa discount, the pump, sending unit assembly, pulsator, both front hub assembleys (premium brand) anda  filter for like 230$, and if it comes down to it, a brand new tank for 80$, my tanks on empty and i dont have to money, nor do i want to fill up a car with a bad pump, and its over 100 miles away. But my parents are gonna put it in the garage, so moisture should be a minimum. I Know my pumps bad, it went from Wirrrrr quick, to blub bleh blub blub all slow, to now not even making noise, and taking a good 5-6 tries before it suddenly jumps to life, lol.

Dont know what you are asking about the wiring, However has anyone tries rewiring the pump like this -

The wiring probably varies from some cars to the others. I believe there's a tag on the fuel pump harness somewhere that has one of those three letter codes listed.

I don't think anyone with a TGP has tried that yet. It might help some. I can't remember what size our stock wiring is. If the 2nd gen cars have small wiring, ours more than likely have the same size.

When I did my 255 walboro I just took the stock pump harness and cut off the pump connector and soldered in some blade connectors, heat shrinked the wires and zip tied them in place on the steel lines above the pump......the walboro I bought cost 100 bucks but it did not come with a screen or wiring harness so I had to make it work.....Not sure what the  "correct" answer is but that is what I did .

My fuel pump went out coming back from Texas, and they wanted to replace the wiring also.  Just got the pump replaced with a stock one, Have never gotten around to rewiring it with the thicker wire.  It does have small wires. 

I did this wiring mod on my 1997 and saw a small increase in Fuel Pressure.
