Re: 2000 6.0L runs rough and stumbles
that is correct. it is on the drivers side fuel rail. check and see if it is good is by running the truck or cycle the fuel pump with the key, shut it off then up plug the vac line from it. If gas comes out of the port then it is no good. A nother sure way to tell is if your truck starts hard ie cranks over for a little bit before firing up. the pressure reg is a dealer only item and is just over a $100 bucks.
a broken valve sring wouldnt trip the check light.
