I received and installed a FASS 95 when I replaced my injectors (just about a year ago) FPR crapped out a week later, replaced with a genuine Bosch, no problems since. More recently, my pickup has idled *slightly* rough sometimes (not enough to move the tach needle), and when I unplug the lift pump, it seems to stop. Problem is minimal/gone on high idle. I am thinking it’s a excessive pressure issue. If so, I would like to get a lower psi spring. Research has not brought up definite part #s pertaining to lower pressure. If anyone has some spring #s available to share, it would be much appreciated. If not, I’ll call FASS and iron this out.
