I finally got a fuel pressure guage, one that mounts on the fuel filter. After turning the ignition on(but not starting the car) the guage was reading 38 psi. I have a 255lph fuel pump btw. Just wondering if anyone knew what psi they put out because I was under the impression it was higher than that. Maybe im not understanding something right so let me know. Thanks.

well I believe you need to have your car running for an accurate reading..
x2, it will jump up when you turn on the ign when the fuel pump comes on.
