    Does anyone know if the regulator that goes with the holley blue 14PSI fuel pumps need a return line? How do they regulate the pressure?

    From what I remember it is only a dual port regulator, one in and one out. It internally regulates without a bypass port. On the project I'm working on we are ordering the Holley 12-803BP regulator. It is a 3 port with return and are going to regulate the pressure after the carb.

    i run a holley blue on my truck. but the old guy told me to throw away that regulator that came with it. i have a BG regulator, after the carb as well. this guy has raced for years so i guess he knows what he's talking about

    What do you mean a regulator after the carb?

    +1... This is what I had on my old K10 and worked flawlessly.

    The part is a BG "bypass" regulator. :wink1:

    the reg goes on the out flow side of the carb supply line (behind the carb by the firewall)
