Just wondering for those of you with a fuel pressure gauge on your car, what are you running for a baseline idle fuel pressure and at what rpm? At close to 1500 rpms my fp is about 45psi. I'm reading this off of a B&M FP gauge that I got off a parts car and it is attatched just after the fuel filter (common sense says the fuel rail would give a more accurate reading but it's a direct bolt on to the fuel filter). Anyhow, I'm just wanting to get a general consensus of what fuel pressure should be.

I have my regulator set at 41 baseline with the vaccum hose off. 38 with it on. No way to tell what it is under power cause its under the hood.

My guess is that it's somewhere near your 38 when it settles down to idle. My problem is that I can't let the motor get warm enough to where it settles down below 1000 rpms idle cuz my radiator fans went kaput on me and I really don't want to melt a new motor by accident.
