I have purchased a VR-4 super charger. I am going to run it on a 331 motor power elbow intake and lower matched one. 75mm throttle body & mass air. i also got a larger set of fuel rails for the kit. What size fuel pump do i need? I am haveing a hard time with the whole build. Too many cooks if you know what i mean. I just want to know what you people say about it. is a 255lph pump big enough. or do i have to step up to a 310 or some thing.
