aeromotive regulator problems

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??

Weird. fuel filter ok? Check valves in the heads clogged? Pump running rampant? It sounds like the check ball in the regulator is jammed into the seat, but I don't know how it could be.

It sounds like your return like might be kinked or plugged...
