I have a Weldon electric pump and a Weldon bypass regulator. The regulator is connected directly to the pump, and they are both located behind the driver's rear tire, behind a shield. The bypass regulator sends excess back to the tank, and knocks the pressure down to 12 PSI. I have a non-bypass regulator (Aeromotive) at the front of the car that knocks the pressure down to 6.5 PSI and feeds the carb. All of my plumbing is AN 8 except from the front regulator to the carb, which is 2x AN 6. This is what Weldon recommended, and it works.
Tank > Large filter > Weldon pump > Weldon bypass regulator > Large filter (at front of car) > Aeromotive non-bypass regulator > Carb
