New record !
Congrats on the new record for the shortest living thread Ric, this ONE only lasted like 9 hours shattering Andy's 12 hour record :B I might mention Ric also hold the highest non sticky post count ...

You two nailed one of my positions...that all things designed/engineered
is NOT for the good days out there, but for the worst day when Mr Murphy
crosses your path
No time to go back to the store for bigger/better/etc...nor time to
resetup
Either it is there spot on or not
A lot of thought goes into designing anything and if any potential
maiming/killing/etc, then even more along with even more rigorous
CDR's (critical design reviews)
Amazing to me, and more so because of my background in design, that
these OEMs (including Bosch) insurance and legal teams have NOT put
their foot down on the CP4 design (including system)
Sure you can NOT design out every possible scenario, but since the
CP4 is now well known to have this, that many badges have the same
to similar issues...the writing is on the wall and the first one
to experience a death via a CP4 failure will have a field day in court
Another scenario is someone crossing a rail road tracks and the CP4
decides to blow up....when a freight train, passenger train...any train
is barreling down at them at +70MPH. Average locomotive engine is
around 500,000 pounds...just the engine...then add the rail cars behind it
Learned a ton back on that CP4 thread and nothing I wanted to learn
and now think Bosch engineering isn't stellar anymore. Design/engineering
101 stuff plainly missed or ignored after the discovery thereof...
Another amazing position is that it is well known that all of the
big three diesel's use the Bosch system. That not just Ford has had
CP4 failures, even Porsche/VW/etc. But only one has NOT warrantied
or taken care of their product and customer
Blind loyalty is common...ever try to show a Tundra owner how their
own vehicle label says it is NOT a 3/4 ton?

We must admit here on the tow vehicle forum, shoot the forum in whole, that we are by far just a tiny fractional percentage of total diesel vehicles being used here in North America right now.
And yet, and seemingly against the odds due to our small numbers, we have still suffered two confirmed failures of the Ford HPFP. Most of you remember Ricatic, but there was also a Canadian poster on here who had the same problem.
I PM'd this Canadian poster. He related to me that Ford tried their trump card, water in fuel routine with his vehicle also. Unfortunately for Ford, they had also just recently changed out the fuel filters for this vehicle. Based on this evidence, within their own (Ford's) maintenance records, Ford did in fact, begrudgingly, warranty the HPFP replacement and all assorted costs associated to the replacement, on his vehicle.
So that is two, as I said, from an amazingly small sample of operators.
I want info on this. I own one of these 6.7L Ford diesels.
My biggest fear is that someone, somewhere, is going to be hurt badly or worse by the sudden failure of these pumps. As they seem to die suddenly, without any measurable warning symptoms, I can see someone, attempting to merge onto a busy interstate, having his vehicle chug and die just as he leaves the on ramp and arrives in the traffic lanes, with an 18 wheeler bearing down on him from astern.
It won't be a happy ending or a pretty picture.

You have hit the ball out of the park...but I was surprised that I had to be remembered...:B:B:B
Seeing that I am one of the owners that has experienced the dieing of a 6.7 Ford HPFP, I can assure you that your semi-doomsday scenario is very possible. When the Bosch CP4 HPFP died on my truck, it just shut down like I turned off the key...just as I made a right turn off the freeway exit ramp onto a busy highway. There is no warning...it just quits.
If this indeed happens to someone towing a trailer as they merge onto a freeway, they are toast. You lose the power steering and the power brakes. Your 18 wheeler scenario will become a nightmare...This is why the NHTSA needs to keep pressuring the manufacturers who use this delicate pump to fix the problem...we know from experience that it does not take any water to destroy the pump and a few ounces of water will take it out even quicker. The water separator/water in fuel indicator is useless. It takes 7 ounces of water in the DFCM before it reaches the WIF switch.
