    Hello all. I am looking for a return-style fuel pressure regulator. I am running a pair of 1964 Carter 3705 AFB carbs on a Stage II Ramcharger cross ram. I have a 1/2" line from my pumps up to the front of the car. What size return line should I run, and what regulator do you all recommend? I want to run a separate line to each carb off the regulator. Thanks.

    1/2 inch return. You want the return as big or larger than the supply. If there is pressure restriction in the return, it will affect the regulator.
