Well I dropped the tank and changed the fuel pump , put the fuel pressure gauge on the rail and started it up to my surprise I get about 52lbs of pressure , I think shit ,(Thats what I was getting before I changed the pump) well I take it for a drive and it runs very well , no stumbling or spuddering under a load , problem fixed I hope , later that day I also changed the fuel pressure regulater under the intake which wasnt to bad And my truck seems to start alot better know ( I did however break an injecter clip reinstalling the upper intake and where did the piece go , Yup rite doen the intake (LOL) so it made alittle noise when i started it for like 3 seconds Rattle rattle then went away thank god it was only alittle plastic piece . After all this I Dont know if my NEW fuel presure gage is bad or not >>>
