Thread: ?? on mallory fuel regulator

  1. #1
    here's my plan gonna run two mallory comp 140's with a 150hp nos the pumps came with regulators,two outlets and one inlet does any one know if i need a fuel return line on the part# 4207 regulator? i have check valves and plan on running a pump on each tank will the regulators back flow without the checks in front

    the 4207 is a dead head regulator. there is no prevission for a return line on them. if you want a return line you will need to get a differant regulator for the fuel supply. but i think the 4207 is fine for the NOS where i believe there is no need for a return line. i use the aeromotive 13207 bypass regulator and like it very much. it allways holds a setting even when the temps change.
