There is a stock sensor on the driver side fuel rail. You can also monitor the fuel psi with SCT using a laptop and SCT Data Link software. My fuel pressure averages 40 psi at idle.

Yeah I figured it can be done by datalogging, just wasnt sure. I tried doing it to my car last night but it said it couldnt recognize the sct device. I redownloaded the program and going to try it again today
