Thinking of getting the Carter electric pump that states has a "internal" regulating valve. Do the people who run them, run them without a pressure regulator?

what's the outlet pressure

what's the outlet pressure


6 psi

6 psi


no need for a regulator then

Just be careful about running only a low pressure electric by itself. 6 PSI at the pump doesn't mean it's going to be anywhere near 6 PSI at the carb during a hard launch.

There's a reason why most setups have a pump at the rear running at a higher pressure (~15 PSI) with a regulator up near the carb to knock it down to final (lower, ~6 PSI) pressure.

I run a low pressure electric like that in my Malibu but IN COMBINATION WITH A BLOCK MOUNTED MECHANICAL PUMP. The combination of the two can fill a bucket in no time and pressure holds at 6 PSI like a pit bull under all conditions.

I ran a carter pump with the larger inlet and outlets and that pump had a lot of pressure creep and did not stay very steady, then last year it burned out, it was 15 years old. I bought a mallory that needs no regulator and that one is steady as a rock at 5.5

I'm using a Carter electric mounted next to the gas tank and the pressure at the carb is 5.5-6 psi. (hooked up a mech. gauge 6 inches from the carb to test)
