Loss of Power, Possible IP/Injector Issue
It feels like the engine used to "grab" more if downshifting to reduce speed with the brake. At this point, I scheduled a compression test for this upcoming Tuesday. After a closer review of the maintenance records (Which seem fairly complete back to 86), it looks like only 1 injector was...- Msch3390

Final update! It holds prime now. It was the Mechanical fuel pump. I really don’t regret replacing the rest of it, there was air getting in and fuel getting out of some of those other spots. Thanks for the input everyone!- Msch3390

6.9 IDI Hard Start/Air Intrusion
Update #2 I found this guy, runs from the hardline coming from the tanks, to the hardline going to the mech fuel pump. It’s sucking air. My question is should I be installing a 1 way valve or check valve on this line?- Msch3390

6.9 IDI Hard Start/Air Intrusion
Update: I have replaced one fuel cap that looked like fuel was getting around, and the bowl to the fuel water separator with a plastic see through one. The truck is still doing the exact same thing.- Msch3390

Hello all, Working with an 86 6.9 IDI in an F250. truck suddenly began losing prime about a week ago.
