The VW pumps in question for the most part are 1 piston variations of the 2 piston pump on the 6.7 and Duramax. There are VW models that use the 2 piston pump, but their failures appear to be much less common than their single piston cousin. Either way be it single or double piston they are in the same family and of the same basic design.
To be clear, these are not VW pumps, they are Bosch pumps, and they are CP4's, the 4 designating the 4th generation of common rail designed pumps by Bosch. Any vehicle company can use them, just contact Bosch, and they will custom engineer a fueling solution tailored to your needs on your diesel.
I have read that Mercedes uses these pumps with no problems. But that they spec'd stainless steel cylinders instead of aluminum because of the poor lubricity on american diesel.
Don't know if that is true. If it is, it sounds like a good idea. And perhaps GMs claim of fuel system hardening entails this spec as well.
Well after reading endless posts on this subject I know that if an after market solution becomes available, that won't affect the rest of my warranty, I'll be on it like snot on a rag. I will spend the dollars to insure the soundness of this fueling system and the peace of mind it will buy me. I hope that the fuel up here in Canada, plus the additon of FORD additives will keep me issue free. I have no plans of giving up on this truck since it is definitely the best truck I have ever owned. I too don't see a "sky is falling" scenario, but if the after market comes up with something before this whole issue is resolved, and it meets my criteria, I'll spend the bucks.
How does anyone know if a future aftermarket HPFP will be any better?
What about the warranty with the future aftermarket company?
I’m not being combative, simply asking.
Valid question. Given the history of the aftermarket it's a bit of a crap shoot too, but from my own experience if you are willing to spend the dollars you can usually get a superior product going this route. The old adage of "Get what you pay for" generally rings true. Afterall, do you think Ford might be getting what it paid for with this pump? I certainly didn't spend $78K after tax, to have to worry about my fuel system. Yes Taxes up here in Canada beat the crap out of you. Possibly an after market pump won't be the resolving issue. It might be a combination of things between fuel filtration, water seperaters, etc that bullet proof this fuel system. With the dollars we spend to purchase these trucks we shouldn't have to spend the dollars to make them bullet proof, but to protect these kinds of investments I would rather spend $5K making it bullet proof than $9-11K after the fact and having the same product. Some people tune, I'd rather bullet proof. Hopefully I won't have to.
Continue to buy your fuel from high volume stations. Those VW's and Audi owners are city folks that go to their local station in the city or town and buy their fuel. They take at most 15 gallons to fill up. The Fuel in the ground sits and deteriorates till it is sold.
NinerBikes is right in his sounding the alarm I feel. The Same Pump will do the Same thing in our trucks if it is fed the Same bad fuel as a VW or Audi.
Rick did no wrong. Ford has not experienced the same issue Because as owners WE Know where to Buy Fuel and Why we don't buy from low volume stations.
The Sky is not falling and I will still tell anyone that asks to drive one is to own one in a day or so. I will also tell them where to buy Quality fuel here in my neck of the woods and what to look for when on the road.

...then explain my failure...I know where to buy fuel...if it happened to me, no one is immune...you are right though...to drive one is to own one
Rick's situation is the most alarming of all I've ever read. His situation rules out owner neglect in my eye which is always something I question when I read people's stories. To read a guy having problems when he takes as good of care of his truck as I do of mine really puts a shiver down my spine.
Of course my truck is not going anywhere, but I am disappointed in Ford. It really makes me think twice about the risk of being a diesel owner today. I thought I was avoiding all of this when I upgraded from my 6.4.
Rick
I understand that you know where to buy at your Local High Volume Dealer.
Stuff does slip by and Stuff happens.
As a group we do buy our fuel at the High Volume Dealers for both the Quality of the fuel and the Price Break we get.
What Niner is saying is that there is a problem with the pump and bad fuel. What the investigation is looking for is the trends to see if they connect. You got Bad Fuel and it did the same damage to the pump as VW and Audi have experienced. As time and the number of truck fueling incidents compile up more will come to light and You will be compensated for your repair to your truck.
Bean Counters and price points drive the industry. Remember the Ford Pinto and It's Fuel Tank exploding on a rear end impact. Ford denied responsibility for awhile till the numbers provided the proof. 6.0 and the 6.4L engines are another issue that Ford denied initially then finally owned up to. They the engineers Spec something and then it is tweeked to get the cost down.
Does it perform as well?
Will it last as long?
The investigation will take time.
Once it is fixed rekindle the Love you once had for your old truck. It was not her fault that she got Used, Abused and Tattooed.

The problem with this comment is that it was never proven that Rick got bad fuel.
It was only assumed and reported that way.

...thank you...someone got it right. I found out a lot today when I picked up my truck...and several boxes of parts

Exactly.
But to wait for proof or conclusive evidence and to think & speak rationally until then wouldn't allow the spreading of hysteria & creation of hype.
This whole thing reminds me of a movie in the 1980s called The Blue Lagoon with Brooke Shields.
Two young children become shipwrecked on a deserted island and grow up there all alone, without any continued education or additional learning from the real world.
With nobody to correct them and teach them, their sense of the world is only what they know in their minds.
It's the same thing here... basically, a small collection of people on the Internet telling their notions of what happened to them and/or what they (think they) know, and others make assumptions & suppositions and draw conclusions and make inferences.
And, spread fear & hype.
All based on incomplete and potentially inaccurate information.
Statistically, engines & fuel pumps belonging to members of this lone group of Internet users would be an invalid sample as it (the sample) is not random enough.
