i just whent down to the parts store and looked up an electric pump with a low psi. readout....... usually a low psi pump will do anywhere from 6-12psi depending on the brand. you can go with a holley, weber, or a edelbrock pump.... they all have low psi pumps you can use. if you can, buy a spare as well
Dont use the Holley Blue with out a regulator.. those are high output psi pumps, i know becuase it wrecked 2 carbs before i figured that out.
