6.4 High Pressure Fuel Pump (truck still sitting outside dealership) 1 month now

To clearify, Ford sampled the fuel in my buddies truck...
Ford in san antonio took the "sample", and then flushed / refilled the fuel system. Fuel pressure is only around 5k at idle, and that's why it must have stutered causing my buddy to bring it in the first place.
Since it wasn't sampled correctly, how can they prove bad fuel? The insurance analysis was only done against fuel from the seperator, which is to be expected. Sounds to me like ford is tired of paying out on these delicate little flower of a fuel system going bad.
This is the same ford that's producing mustangs that are dropping trannys. EDITED BY CRAZY You know, with asian manufactured getrag designed trannys.
Do I need to get an airdog or the like if i want to keep my 08 going long? I can't afford 10k on this thing... And I just bought my wife the new limited explorer. I used to love ford, but they are inovating too quickly, and quality isn't quite job 1. That would be okay if they would cover the fixes under PUBLISHED WARRANTIES!

Thats a junk design, slice it any way you want. As for the engineers, if any of those overpaid virgins took a glimpse of daylight, and actually looked around at how these trucks get used, they'd realise that the fuel system is a liability to the truck. The fuel filtration needed to be able to accomodate the fuel quality commonly supplied to the truck, not their ideal conditions wishful thinking.

first off I did list the correct way to do a sample from the wif. If the tech took a sample, then an inspector took a sample it was done both correctly and fairly.
second 5k psi at idle is spec and also what it need to light off. so your information is off again.
base fuel pressure is not an issue, the pump has a 6-10psi output. thats all.
what you can do is drain the wif on a normal interval, replace the filter when they should be and avoid fuel station that have had fuel droped on the same day as well as fuel dealers with a slow turnover rate.
so far as the mustang trans issue goes. us tech new about that long before it happened. No idea what they were thinkin gon that one. but yet again it has little to with design flaws in the unit so please if your going to bash do it correctly and state fact not opinions. the issue is the trans was not ment to support the hp/tq the enigne puts out.

Just to give folks an idea of what 50 parts per million water contamination in fuel equals. 50 drops from a eye dropper in 50 liters of fuel (13.2 gallon) would be 50 ppm contamination. 150 drops in a full 40 gallon tank would also be 50 ppm somewhere around a tablespoon worth.

There are some that have, and the amount it happens may not be too great, but the cost is a killer.
I remember when lots of 6.5 chev diesel burned pumps, and 1600$ seemed crazy, now the 6.4 with a 8-12k$ repair for the fuel system?
for how much the parts are worth, they should have been protected better.
Like I said, it seems they were designed without real world operation in mind.

Remember where your HPOP was on your 7.3L truck? That's where I think they should have put these pumps, as it likely would have been possible to replace without removing the cab or paying for so much labor. If they had been designed for easier replacement the cost of such a failure would be drastically lower.
Not that I think it's a bad design, just an expensive one to service when things go wrong. Navistar designed the engines for not just Ford pickups, but their own medium duty units as well, so there's only so much that can be done to engineer the engine around the platform. So I don't blame Ford for that, this is a Navistar problem!
Cheezit, how many hours labor to replace a HPFP on a 6.7L?
