Is this normal?
When I first start the truck and drive, my fuel pressure will stay between 15-17 psi during normal driving. That is exactly what my pressure is supposed to be at.
After about 20-30 minutes my fuel pressure will drop to 14-16 psi while normal driving.
After about 1 hour or so of straight driving I was seeing 12 psi during normal driving.
When I shut the truck off and let it sit for awhile, then drive again, my fuel pressure is back up to normal.
Fuel tank is always full(close to it) when this happens...sensor is right before the CP3.
I'm lost...is my second Airdog going bad? Or could it be the fuel pressure gauge?
