My modified fuel pressure varies when I am trying to set it at 6 - 7 PSI. It swings real fast between about 3 and 9 psi. I tried another gauge and it did the same thing. Someone said it might be air in the line. I pressurized the fuel system and only found a little leak in the return line. I don't think that was the problem.
Could the return line aerate the fuel since ot only dumps to the top of the fuel tank. I wonder if I should have a tube down into the fuel on the return?
Any thought on why the fuel pressure should bounce so much?
