mechanical gauge located after fuel filter, FPR located before return line. I think I'm going to disconnect the FPR and leave the gauge hooked up and see what it reads then.
Its an old filter, I wonder if a clogged filter would give me that high of a pressure?
Fuel setup
Supra fuel pump
550 primes, 1600 seconds
autometer ultralight mech gauge
FPR is unknown, ima post a pic of it and see if someone knows who makes it.
