If you want to win at an EFI conversion and have it be reliable, no matter what, you need an IN-TANK fuel pump with a return system where the regulator is AFTER the fuel rails. Your fuel will not boil off, you won't have fuel pressure issues,
Given I know nothing about the aftermarket systems and set up, pit falls & nuance’s, why is a regulator after everything in the return line?
*I Thought* the regulator was before throttle body. And the return line was free flowing into the fuel tank.
