carter electric fuel pump
Is anyone running carter electric fuel pump and if so how do they preform I order p4600hp 100gph 6-8psi to run behind a 454 with no regulator or return line. I was told if i run a return regulator it will last longer and I was also told it would lose psi. what kind of psi do you have? I think i should have just have just went with the 15-19psi version and ran a return regulator.

To really run a good quality fuel system, you need a regulator/return. The regulator cuts the pressure at the point it is set for and returns the "extra" fuel to the tank. If you have a pump that puts out 100 gal per hour, and you are using 5 gal per hour - guess what happens. The pump is basically deadheaded and heats the fuel. The hot fuel is not good for the pump or your engine.

No need to go with electric fuel pump, I have been using the same Carter Street Super Fuel Pump for many years on 400 - 600+hp engines in my Corvette. They flow 120gph and good for 600HP @ 7000 RPM

73 corvette I went ahead and order p4601hp pump 9-15psi 100gph and holley bypass regulator. I read a few people could only get 5psi from the 4600 pump and i didnt want to under fuel the holley.
i did order a cheap summit fuel filter. i have holley inline filter and cheap clear filter to see that its getting fuel. I was thinking put the summit filter first, pump, holley filter and then the regulator. Im thinking i might ditch the clear filter.
I also order a vod fuel gauge that is not fluid filled.

I'm running a Carter electric fuel pump and it works perfectly on a 1970 Corvette L-46.
I believe this is the pump I'm running:

The Carter fuel pump was on the car when I bought it, originally I was going to replace it with a stock setup, but the system is trouble free and the car starts instantly, even after setting for 6 months in storage, so now I've decided why mess with a good thing. The electric fuel pump is staying.
FWIW: when you turn the key to the ON position you hear a mild hum, once the engine fires the sound is no longer noticeable. I only mention this because some don't like the hum of an electric fuel pump. Personally I find it comforting in that I know the engine is getting fuel.
