A couple of days ago I noticed that my truck was idling rougher than normal. I checked my aremotive fuel pressure regulator and the pressure was up around 100 psi! (Normally its 64 psi). Then I shut the truck down and the pressure stayed at about 40, and did not bleed down like it should. I then started it again and tried to adjust it back down from 100 and 70 psi was as low as it would go. Any ideas??
After making a couple of phone calls and a little more trial and error (removing fuel line from reg. after power is off and pressure stayed the same)I figured out that I just had a bad pressure guage. The reg. is just fine!!
