In-Tank Fuel Pump advice
I'm going to be installing a FAST EZ-EFI system into my '91 Camaro for my 383 Stroker. I'm looking for a good quality in-tank pump to replace my factory pump. I want something that's going to get the job done for the 500hp but also isn't going to whine and scream like i've got a jumbo jet living in my gas tank. Does anyone have any suggestions on what to use?

Re: In-Tank Fuel Pump advice
you may want to look at the walbro 340 or comparable aeromotive pump. they'll flow what you need for those demands and then some.

Re: In-Tank Fuel Pump advice
Does anybody know is this Aeromotive Stealth fuel pump 11140 suitable in tank assembly to my car Pontiac Firebird Trans Am GTA 1987? What is difference about this Aeromotive 11141 fuel pump exactly?
How much this aeromotive Stealt Pump could produce horse power?
Now I have Holley HLY-12-903 fuel pump in tank and it doesn't flow enough, that seems to be like almost WallBro fuel pump.
Now I have 520HP on rear wheel. My car is Paxton supercharged with 13PSI boost.
Does anyone have this Aeromotive fuel pump? Is this OK?
Thank You!

Re: In-Tank Fuel Pump advice
I used the 11140 pump, but the 11142 one would have worked out a little better I think.
I can't say whether it would be enough fuel for you or not since I'm making much less power.

Re: In-Tank Fuel Pump advice
But this 11140 (in tank version) seems to give 30% more flow than Holley HLY-12-903 fuel pump.
If this fit in tank then this could be the solution.

Re: In-Tank Fuel Pump advice
I use a pump from a turbo Toyota Supra. It's not a direct bolt in, but can go in a third gen tank with a little fab work. It has proven to be a very reliable & super quiet pump. I had a 255 Walbro, and it couldn't keep up on the dyno. The engine would go lean at about 5000 rpm. The Toyota pump would supply enough to go to 6600 rpm, never ran it any higher than that. The engine is a LS1 that made 420 RWHP. Rock Auto has the pump, part #9500155.

Re: In-Tank Fuel Pump advice
As already mentioned, the Toyota Supra pump is a good choice. I tossed a Walbro in the trash and installed the Supra Turbo pump in my 87 GN. No problem with fuel delivery volume or pressure. A near drop in. Will just fit in the hole, and have a non stock sock filter set up. Not rocket science. Get a hot wire kit, as the factory wiring is too light to power the big pump! Racetronix has it. Thanks, Oldtimer.

Take care.

Re: In-Tank Fuel Pump advice
I've never understood those $100+ boost a pump wiring kits either. I mean, I know there's some voltage drop from the relay to the pump, and I know some of them actually up the voltage to the pump, but it still seems like a band aid to me. I'll be using a Bosch relay and some 12ga wire when I relocate the battery to the back though. As I said before, I'm happy with my aeromotive 340.

Re: In-Tank Fuel Pump advice
The Racetronix set up replaces the wiring to the pump, including the bulkhead connector. Not a splice job down to 16 guage wiring. My experience with the Buick GN set up wasn't bad. On those cars, some folks were having problems with the big pumps overheating and burning the stock wiring. Poke your head in at the TurboBuick.com site and check it out. Tons of info, and debate, on the fuel pump issue. Oldtimer.
