I'm mapping out my fuel system so I can figure out what fittings and how much line I need. I am running two holley black fuel pumps and I'd like to run a return line instead of dead heading the system. When running a return line do you put the regulator after the carb to hold the fuel back? If you put the regulator in front of the carb the fuel will just flow right by the carb back to the cell right? I've always used a holley blue and dead headed, so I'm new to the return line set up Thanks for the help

Call Holley Tech and ask them the proper way to run one on thier regulator. I use Magnflow pumps with BG regulators now and the return line is from the pump to the cell, not from the front of the car I called Product Engineering on their regulator and they said to plug it(the return port) off if I wanted to use the Magnaflow pump

I use a mallory 250 pump and RobbMc return style regulator. With this system, the return line goes from the regulator back to the tank.
