    Finally got around to installing my fuel pressure gauge. With KOEO I'm seeing about 41 at the prime. With the car running it seems to sit around the same. It will spike to about 47 with a punch of the gas. Haven't driven it yet so no idea what cruising or WOT looks like.

    Does this sound about right for a stock 2000 GT? I know I need to change the fuel filter again and as far as I know the FPR is original to the motor. There is no gas leak or smell when I removed the vac line to check the FPR. This is also on a relatively new stock Delco fuel pump if it matters.

    Yeah, that's right.

    They are a 3 bar fuel system that run around 41-44psi or so. If you floor it, it's likely to come up a little because of the vacuum line regulator.
