7.3 fuel pressure regulator issues
Last night my truck felt like it had clogged a fuel filter. I checked my vac/boost gauge and it was fine. Temps good. Plenty of fuel. I switched back to diesel and it died. Back to WVO and it limped home. Parked for the night, I switched back to diesel and let it idle quite a while. It was still running rough, just like low fuel pressure. When I turned over the key I could hear the fuel pump working.
This morning I checked the fuel bowl without draining it and found the fuel level down equal to the pressure regulator/fuel return outlet. Hmm... that doesn't seem right. There should be no air in the fuel filter housing, right? The fuel filter looks fine.
I noticed what looks like rubber sticking out from the fuel return line where it bolts into the pressure regulator. Sure enough, those o-rings are shot.
As one who works with chemicals, I don't see anything in WVO that could cause this type disintegration. They aren't swollen like from using a solvent or anything.
Has anyone else had problems with the o-rings in the factory pressure regulator? By the way, the local dealership didn't have one in stock. Their price would have been $78 plus tax and any expedited freight bills. I ordered it from www.thepowerstrokeshop.com and their price was $58. Even with the more expensive Saturday UPS shipping it will still cost within $2 of the local dealer. Plus, they had it in stock and shipped it out today.
Hopefully that is all that's wrong with my truck. Any ideas?
Todd
