Need help...08" 6.4 showing high pd on fuel

[StillShockedIwantaFORD]

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 i'm stumped on this one

Lets keep this guy in a

Is there any known fuel mods or anyone knows where the sensors on the fuel delivery system are?? Somebody has to have had this same problem.

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

[StillShockedIwantaFORD]

Thank you.. I just let him know. I will keep you informed.

Talked with the guy this morning. His mechanic wants to change the high psi fuel pump also. I will post the results

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.

[StillShockedIwantaFORD]

They guy at the 4x4 shop refused work on it and sent him to a diesel mechanic that works on strictly F250's. This guy is supposed to be the guru around here..

This is EXACTLY why I.decided to buy new with a extended warranty

[StillShockedIwantaFORD]

The mechanic is changing the sensors 1st. He quoted $10k for that fuel pump job. But it would be covered under a warranty he bought.

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

the supposed F-250 deisel specialist couldnt find the problem... hes bringing it to FORD
