my cars fuel pressure sits about 59 psi while fueling but goes up to 68 psi while driving. I was sitting in it watching the gauges while it was warming up and it would surge every now and then. It would flutter from 59 to 70, 80, and even spikespike to 100psi. it would never stay at that high of psi just surging that high and drop back to 59psi. Any ideas what is going on ?

What has been done to the system?? Stock,? New anything?

What pump, and what size lines? AFPR? Using a voltage booster? Without knowing anything else, it sounds like you're running too small of a return.

Sorry it took so long to reply back. It was a loose wire. It now sits and holds at 69psi. Thanks
