What should my Phantom aftermarket fuel pressure gauge be reading at idle..car has stock injectors and stock regulator. Right now it reads about 30 psi is that right?
Is this with or without the vacuum line hooked up at the regulator?? I'm assuming this is with the line on and yes thats about right, without the line attached, your fuel pressure will be at the max as if you were at wide open throttle and it should then read between 38 and 42#'s.
