Default Fuel pressure regulator return line.
Installed my Webers. Using a Mallory fuel pressure regulator rated 3to 9 lbs. The fuel line is AN6 and the return line is AN4. Fuel pump is a Carter mechanical street pump putting out 6lbs. I can not get the pressure to adjust below 6 lbs. It should be around 3 lbs or less for Webers. Any sugestions other than tearing apart half the car to install an AN6 return line?
