Any recommendations/brand for an electric fuel pump. 312 4 barrel. I assuem I need a regulator, any recommendations on that.

How are you using it? Basic stock or mild to wild? I installed a standard inline pump at the tank and a Holley mechanical high performance pump for a 390 in the stock location. I only use the electric pump for all out runs with the McCullouch supercharger. Otherwise the Holley handles it. Chuck

A 300 HP engine needs about 30 GPH at carb inlet pressure - and you can get that with a mechanical pump. The 428 FE police engine pump is a bolt on  - if you don't need the vacuum pump for wipers. It is close to 80 GPH with no back pressure.

This is the published data for the Holley 80 GPH pump - with the 4.5 psi performance shown in red. Solves some problems with fitting and controlling the electric pump. And I'm sure your carb won't starve - unless the suction line is too small.

Richard,

Greenbird is right on a number of issues. An electric pump needs either a oil pressure switch or a tachometric switch fitted. It's just not safe to do so otherwise. A filter before the pump with sufficent capacity, Holley Electric fuel pumps prefer return fuel lines, you can deadhead with a carter or similar and then you need the correct regulator for that type of system.

Again on usage. A car that can generate 1g's accelaration will need in exess of 8psi to get pressure at carb pumping from the rear of the car and there are plenty of other loss or retriction issues to consider.

Noise??

There's a lot to consider with a electric pump but hard to beat for real performance use.

Cheers
