Do I need a fuel pressure regulator?



Hi, guys.

We have my son's 64 Dodge 880 running like a top, what with a carb rebuild, MSD ignition, and new fuel pump. One of the things we wanted to investigate was just what fuel pressure looks like. We installed a brass tee with gauge between the pump and the carb and were surprised to see higher pressures than we were led to believe would normally be the case. At idle we're seeing 12-13psi. Rev'ing the engine to 3,000 rpm or so we see a stable 8 psi.

Aren't these pressures quite a bit higher than what the carb likes to see? I believe the specs for the Carter BBD are 5-9psi, but I may be wrong. It's probably the higher pressure at idle that worries me. So the question is, should we install a pressure regulator in the line and set it to something like 7psi?
