I spent over a quarter century as the equivalent of an "area rep" in the avionics business, and I can assure you that when I went out to look at a problem, my attitude NEVER was to initially find a way to first blame the operator/pilot.
Times must have changed in America.
Integrity, maybe......

The POINT is NO ONE should not purchase or fear their NEW 6.7 Ford engine because of an ISOLATED incident. Or was treated unfairly by a dealership!!
THESE trucks are a HOMERUN built by FORD!!
SOLID great diesel Engines!!!!!!
Until more facts come to show otherwise....everyone needs to relax and enjoy the ride!!!
I do everyday.
Go FORD!!!!!
I would buy them again and again without a hesitation.

That changes things, just a little bit.
It does for me if it's indicative of how they handle problems, however isolated.....

Well, there are tooo many factors for me to throw the baby out with the bathwater.
NOTHING,,,I repeat,,,NOTHING is VERIFIED. On either side, before the denial of warranty repair.

I believe the only way any of us could fairly pass judgement on anyone in this incident would be to see all of the documentation from the initial servicing dealer where the truck was towed, Rick's dealer (I think it was Shepards?), and all of the documentation from Ford detailing and documenting the entire process and reason for denial.
Until then, we're only hearing one side of the story. I feel for Rick but know that there are always at least two sides to every story.

Guys
I believe this is the last I will write about this subject. I am now convinced after reading the above post that somebody is intentionally trying to instill fear about our trucks and the HPFP that resides in it. Anybody who would compare a valve train in what appears to be a motorcycle motor(14,000rpm) to a positive displacement pump that might be operating at 250 to 350rpm is insane. First off the valve in this video is in an open environment with no resistance put apon it except for the downward force from the cam and the energy store in the spring itself. Yes at some point the rpm of the motor will out run the springs ability to open fast enough to keep from floating. The positive displacement pump is an entirely different animal. The PD pump spring is not in an open environment, it's surrounded by the product it's pumping remember up to 30,000psi. After going back and seeing the 3D animation of this style pump you can plainly see the piston operates in a close tolerance bore both at the top and its larger base. This is pretty standard in the pump industry and is what keeps the piston running true and perpendicular. There is no need for bearings because the pump is hydraulically balanced. Every pomponent in this pump relys on the product and it correct viscosity to maintain the proper clearences within it. As for the spring it appears to be in a retainer at the base of the piston and shouldered at the other end where the piston steps down to a smaller diameter. Once again
standard and it works.

I if what you say is true and they found no contamination then I think you got a bad pump that could have had a flaw that was not detected during assembly. Ford should have replaced it it in doubt.
I will sleep peacefully tonight with what I know. Protect yourself and use the additives that you feel comfortable but us something because anything can happen to the fuel from the time it leaves the refinery until it gets in your tank.

Thank you ,thank you and thank you again for pointing this out and being another voice of reason on this subject.

I keep saying one person on this board has had a problem, the engines have been out for 18 mos now. if the problem was that bad I think we would see more issues.
