There was a request for a link to Ford's answer's to the NHTSA investigation posted on a previous thread, since closed. Here is the link:

Ford's NHTSA Answers to the 6.7 investigation

This PDF is over 20 pages long. There are some interesting statements contained in the documents. My favorite is the one where Ford says they buy the pump from Bosch as a "black box" and do no testing of the component. It is closely followed by the tantamount admission that the pump will not provide a long service life when exposed to the poor lubricity fuel found in the US. You will have to do the math using the sales versus failure tables for the US and Canadian trucks. Eye opening difference to say the least...

Too bad i traded in one of those horrible 6.4 diesels that had 100k miles with zero issues for this horrible 6.7!

Quick someone come take this thing off my hands before the fuel pump stops working!!

I'll give you 50 bucks for the 6.7. I'm tired of my 6.4, because at 30K miles, Ford contacted me and said I HAD to bring it so they could put new tires on at NO charge, because there had been reports of uneven tread wear on the Continentals when not properly inflated. Now I have to drive another 30K miles before I get to replace them myself...geesh...at this rate I won't get to shell out 700-800 bucks for another four years.

So far, not a big to do about it but dealers and owners are aware of 6.7L fuel system weaknesses.

I'd hate to have a truck go down with a bad HPFP during Harvest season. Or a bunch of them dead and down at the same dealership at the same time, if it's truly bad fuel causing the problem.

So after all this speculating does anyone really have Real Facts that show it is a major problem with the new 2011 plus ford 6.7 diesels???

Frankly not that I have seen, warranty questions aside I think the actual failure rate is what would be considered normal attrition for the amount of units in service in regards to the 6.7.

"Normal" attrition is one thing.


"Normal" attrition not covered by warranty is another thing.


Depending on batch, there is a confirmed set of cases where an entire batch had failure rates in the double digit range.

If that is normal, I hate to think whether it applies to all vehicles.

If you live and fuel in Canuckistan, your probability of failure is much, much lower, statistically.

Them stanis have it good?

If you can avoid the VAT taxes and such, I guess it's pretty good? I about pooped my pants while in British Columbia at the tax rate on everything. Then there was the price per liter on diesel fuel... ouch! Oppressive. YMMV, things could be better out east.

FWIW, the folks north of the 48th parallel rarely seem to have issues with these failures.... whether it is temperature/ lack of heat related, Canadian fuel lubricity related, low humidity, dew point and moisture in air related, remains to be determined as the root cause. If you live and fuel in Canuckistan, your probability of failure is much, much lower, statistically.

If you live in the USA, all bets are off.

Designs for the 2014 model year (the next opportunity for change) was frozen this past year.

To simultaneously achieve the EPA 2014 emission targets without the higher pressure would require a much larger tailpipe treatment system.

Maybe we should start a pool on what they do.

The alternative is an entirely different manufacturer for the fuel system, which has its own risks.

Delhpi has a market! Square shoe follower. I'd run these as clean as you can before tailpipe treatment before the redneck boys start ripping off the whole DEF /DPF exhaust systems.

Well thats good news for me anyway. I hope.

As usual Ric is right again :B CP3 in the Cummins. We've been told by some member here that Cummins "will have to change it" to the CP4 but he has been wrong before x a million:W
The Chevy ran the exact pump (CP3) up until the HP wars started in 2011. Then GM switched to the trusted CP4 to match Ford's failure rate. Just me but Bosch might have just put more than 10 lbs worth of S*** into a 1 lb bag. At least GM is covering their customers failures, err I mean sweeping the problem under the rug.

Hey, wonder if putting in a dryer inline with the tank vent system to
remove any moisture in the air that replaces consumed fuel...

Right now, the state of the art is to leave many owners hung out to dry.
