electric fuel pump
Best of all, soon I will put an electric pump to my corvette, and I want to give me opinions about where to put, or where people usually put .. well if you think you should put a fuel return line ...
The bomb is going to get sold at summit holley and that brings a fuel regulator.

Um ok.
Anyway, I have a Holley red pump on mine. It is mounted on the rear frame by the gas tank with an inline filter before the pump. Power was run from the starter lug through a relay that is closed by the ignition and an oil pressure switch. The return line is not needed.

I think installing an electric pump on a rarely driven older carburated car is a good idea. Haven't done a C3 Vette, but have a Mallory 140 rear frame mounted set up in an Oldsmobile. Filter is at the tank, with regulator/gauge bolted to the engine. Since the car already had a return line, put an orfice fitting on the regulator and used it. Also wired mine to the ignition, but put another switch in the car so I can stall the engine on an empty carb bowl when I park it. Nicest thing about electric, is the ability to fill the bowl before cranking and usually fire's right up.

stick with the factory set up or maybe up grade the mechanical is the best choice....

Stick with a good mechanical pump. A good one will feed 600HP easily. Why go to an electric pump. I ran a mechancal pump for years and never had an issue. I'd still be running one if I did not convert to fuel injection. There is no need for an electric pump.

Keep your mechanical pump. I have an electric, but I don't have a choice. The early 502 blocks didn't have the provision to mount a mechanical pump. Last year my electric pump died on me. Luckily I was still in my driveway, but it could've happened anywhere.

I think you get better fuel flow with a rear mounted electric pump. I "pushes" the fuel to the front and the fuel pressure overcomes the resistance of the 3/8 fuel line.
I have an Aeromotive Street and Strip electric pump. It's used in conjunction with an Aeromotive speed controller. The speed controller senses engine speed and runs the pump at low rpm at engine idle. It proportionally applies more voltage to the pump as engine rpm increases until at about 2500 rpm the controller applies full dc voltage to the pump. The speed controller cuts down on electric pump noise and pump wear and tear. That Holley shown in the Summit catalog is really noisy.
I installed my pump on a bracket that attaches to the frame where the rear anti-sway bar used to attach to. (I decided not to use a rear anti-sway bar.) Also mounted a large Aeromotive fuel filter on the bracket. The fuel regulator (a traditional Holley regulator) is mounted up by the carb.

Thanks for the opinions, there is something for everyone, the reason for changing the pump is that it was broke and I was giving a lot of pressure ... so that the carburetor is overflowing ...
So for now that pump is not eligible, whether electrical or mechanical
