I am running a 355 with Brodix Spec heads on gas. Will turn around 7800 rpm. Looking at the Pro/cam fuel pumps. On gas do you need to run a regulator or can you just run Pro/cam's 7.5 psi pump and no reg.? I always thought if you run a regulator, you need to have a return line to cell. I see some cars that run one and do not have a return line. Any help is appreciated.
