Agreed. But it turns out the pump wasn't the problem.

 

So, since it wasn't infant mortality, it is probably safe to assume that it didn't come from the factory with that corrosion.

That pretty much leaves fuel as the culprit. How can water get through the separator? The only way I can see, assuming that the filter element was in place, is that emulsified or "solubilized" water made it through.

I'm all eyes for other theories.

Apparently I should have continued to page 4 before commenting...lol.

 

From what we have been told, there were no signs of water damage downstream of the filter.

I'm still not 100% convinced that they use the excact same pump.
Both Ford and GM are big enough customers that suppliers will custom spec one of their standard components for them.

Not sure how to find out 100%

 

If there were no signs of water downstream of the filter, then I really don't understand at all how there could be a denial of warranty. Some signs of water in the filter would be the filter performing as designed. Draining water from the filter housing is considered normal maintenance.

I'd be surprised if the two pumps were absolutely identical, probably just same family, but I could be wrong. Even if identical externally, there could be internal changes.
I'm guessing we'll find out in time, rebuilt pumps should start showing up in maybe a couple of years??

Fortunately, this failure seems to be more of a fluke, at least at this time. Maybe more will show up as time goes on. What is so disconcerting about this is the way Ford is handling it. If the system is set up so that a single (perhaps incompetent) tech can flag a problem as non-warranthy, particularly such an expensive repair, the system is broken. We don't get very much choice where to break down, you might be close to home and a good dealer with a competant tech, or you might not be. How are you supposed to find a good tech when you're hundreds or maybe thousands of miles from home? It's a crap shoot, maybe a very expensive one.

 

A post from the linked D-Max Forum, from a D-Max Technician:

If you think the techs are under trained or lazy in their diagnostics, you ought to talk to the morons they have working at the GM tech assist. Talk about idiots. 9 of 10 times I end up fixing the truck without their help while waiting on a call back from them.<!-- google_ad_section_end -->

Seems that GM and Ford have similar service and Tech Line issues. It's too bad that a service department cannot be trusted, unless you've already had experience with them or have been given a reliable referral.

The following seems to be good advice for 6.7 owners:

• It is worth the expense to have a disabled truck towed to a known dealer.
• Getting fuel at the same hi-volume fuel station, and/or limiting the number of fuel stations used, is important in case of an issue.
• Using an additive with an emulsifier appears to be a bad choice.

Also retain all your fuel recipes in case of a fill up with contaminated fuel.

 

Congrats on the new truck. Since you have both the Duramax and the 6.7 maybe you can give us a real world comparison?

In a separate thread of course........

**Update**

Just read of the issue you are having with the 6.7, disregard the request above.............


It appears that Ford is beginning to take the same stance with some HPFP failures on the 6.7 as they have with the 6.4, that is to start voiding warranties based off of water in fuel issues even though the WIF indicator has not come on.

 

Would you mind posting that pic on here? I'd like to see it and that forum won't let me unless I sign up.

 

Here ya go, Ian. I registered and retrieved it for you!

 

Thanks Tom, reps to you. Surprisingly the pump is not as complicated as I expected.

 

My HPFP was replaced at around 3,500 miles, first they replaced a fuel pressure sensor. 2011 F250.

 

Warranty work? How many days were you without your truck?

 

Yes, two visits to get it taken cared of, about 10 days total out of service. I was also getting a jarringly hard downshift, they replaced the torque converter.

I had a persistent CEL leading to the fuel pressure sensor and then HPFP being replaced. It's run very well since. I opened a case with Ford, my dealership said that was a good move.

 

Explain please.

Is this a case through the Ford Customer Contact Center or your servicing dealer up through to Ford's warranty claims?
