The truck isnt mine. Its a guy I work with. He has a clean 2008 F-250 King Ranch 118,000miles. He said its been lacking power under load and took it to 4x4 Specialists and they told him its showing High diferential psi on the fuel rail. they seem to think its a sensor but dont know excatly where its at. He knows this can get expensive if they have to search for it.

This truck has never had a tuner or anything on it. This guys keeps his immaculate. He's so pissed right now he's talking GM products. I told him to hold that thought i have alot of faith on you guys in here...

PLEASE HELP US OUT:shrug: i'm stumped on this one

Lets keep this guy in a :icon_ford: :wink[3]:

There is a fuel rail pressure sensor under the passenger side valve cover. It's like 40 bucks. If thats the problem.

Changing the hpp is a big job if nothing is wrong with it. I think you're buddy needs to find a diesel mechanic. It's gonna save him money for sure.

Shouldn't cost more than 3k at the dealership to
replace hpfp.
