Default Pump for Fuel Injection?

Anybody had experience with what works?

In tank pump would be the neatest, but is there anything
that would fit with only minor mods?

Other than that, I suppose aftermarket inline is the only way?

Thanks !

What type of fuel injection are you planning? Multi-port injection usually takes more PSI than Throttle body?

Also, what year Vette you planning on doing this to ? 1978-82's may have a similar enough tank design to use a 1982-84 in tank fuel pump.

In line is usually the best way, and to run a filter before and after the pump is a good idea as well.

I am doing the Holley TBI fuel injection, and it comes with an in-line pump that I think is good for up to 25-30 PSI.

The Wal-Bro pumps that come with Holley EFI kits are excellent. Powerful enough for well over 500 hp and dead quiet. Mine is an inline model and I can't hear it at all.

I have a 69 with TPI. I am using an 88 Ford Truck rail mounted pump. It's made in the US by AirTec, about $100 from CarQuest. I am using the stock tank. Supply line off the sending unit to the inlet of the pump that is mounted to the top of the RH frame rail. Out of the pump using the stock line to a filter in the engine compartment. The pump says use a filter on the inlet side, I am using the strainer in the tank as that filter. The pump says it has no suction capability, but it works fine. About 5000 miles with no problems. It is not too loud, you can hear it if you listen, but not too bad. I am using the stock return line-small but it works OK. That being said, if I had this to do again I would find a 75-77 style tank and modify the sending unit to use an in-tank pump. Maybe combine a 75 and a 84-96 sender. I looked into an 82 tank, but the filler is moved in the 78-82 cars. Good luck with your project.

Just hunt down an 82 tank and use an 85-91 stock pump for an L98. You might only have to find a sending unit. I have a friend in Atlanta that has both and could tell you if you could just use the sender. Call John at 770-461-5211.

Thanks much! I figured there might be some later model w/stock efi
that would have a pump setup that would fit, never thought of the 82's
w/efi and the C4 pumps, good deal!
