6.0 Buildup - Your advice wanted.
#330
I just put a fuel pressure guage on it. It was reading 50 PSI at idle. This is on a cheapy Autozone guage. I swapped in the pressure regulator from my 5.3, and it's now 54 PSI at idle, and about 52 with a few RPMs. Is it normal for it to fall for a split second when you blip the throttle? Also, the needle "quivers". I'm assuming this is normal?
Probably time to change the fuel filter if nothing else. It's been a while.
