[QUOTE="Powerstroke Man 6.4, post: 1402427, member: 4573"] I actually haven't gone to see the truck, yet. i'm just going by what they are saying via phone. He says (the guy that's working on the truck) that LPFP connections are tight with no leaks and everything that need to be torqued down to spec was torqued to ford specs. (rail tubes, etc) He said tested LPFP pressure and its holding 15 psi at the AD. (he didn't mention pressure at the fuel cooler). He also said he gets constant supply to the upper fuel bowl with no air bubbles KOEO. There is very little info on this P0090 code, I read if fuse 74 is blown that this mean the HPFP harness is to at fault is this true? Thanks for responding I appreciate it. [/QUOTE]
