I knew people would question what I posted...heck I rarely trust data that's not sourced! So I get what you're saying, and unfortunately I can't get any more specific on a public forum.

All I can say is that this came from a source whom is both trustworthy and in a better position to know these facts than any of us. And yes, GM has had HPFP failures on their new Duramax trucks.

Sorry I can't provide a source!

 

Does anyone know if the Edge CTS monitors anything that could indicate an impending failure of this pump?

 

Unfortunately there is no way to tell if the pump is on its way out

 

So it looks like every one of us is playing a game of Russian Roulette with these pumps!

 

I said it once and i'll say it again for argument sake . The 6.7 motor was designed and tested in Ford's Germany diesel facility. The truck itself was tested in Europe and in the Middle East before it was introduced to the U.S.

Both countries have premium Diesel fuel the U.S. does not. Bosch is German company which provides fuel systems for many diesel cars and trucks worldwide. Their HPFP pumps are tested using European grade premium diesel ,so any of the test numbers posted here you can basicaly cut in half the service life using U.S. grade diesel without additives. Any one can search any car , truck ,or suv , forum that is ran by a diesel motor , post 2007 ( which was when USLD was introduced to the U.S) and can start to see all the fuel system related problems in every different make.You can start to connect the dots.

Ford is a global corporation , so is Bosch , We are in a global economy now. They are not going to change a part which goes into millions of trucks and cars just because one country has bad fuel quality , its all about the bottom line . All the car manufactures have to do in the U.S. is tell you to use an additive in their manual and it covers their butt .

Its only going to be a matter of time before you start seeing posts about peoples exhaust systems getting clogged and tech's blaming poor fuel quality .
Me personally , I wonder if Ford actually built in the cost of a fuel system - $9500.00 , and a exhaust system when it gets clogged -$3500 into the price of the truck , If so i wonder if Ford would let me cancel my full warranty in return write me a check back for $13000.00 and i'll never visit Ford dealer again and fix my truck myself when it breaks? I know that would never happen ,just wishful thinking.

Here is another link http://www.chevron.com/products/prod...ech_Review.pdf

This should answer alot of peoples questions and its a wealth of knowledge about diesel fuel.

Here's another one ,again this is in Europe not in the U.S. Speed | Know your fuels
On the home page click on the left side menu , High Speed Diesel.

 

I don't think so, not if you find and regularly use an additive which will give sufficient lubricity to the fuel you use. Do that and you'll likely find the pump will give many years of service.
The question is, what additive is safest and provides good lubricity?
Another question is why do we in the U.S. have inferior quality fuel relative to Canada and Europe?
My final question is, why did an engine with the CP4.2 get released into the U.S. market when Bosch clearly specs HFRR < 460? Perhaps I'm jaded and cynical, but my chips are on Marketing.

 

What document are you referring to. I don't recall this but may have overlooked it?

 

Great information, the diesel review document is great, thanks! Rep given!!

 

Hey ,Thanks . What really scares me about the review document link is the topic in chapter 2 on the bottom of page 6 , if those findings are correct on the filter and micron sizes ,then the filtering system on our trucks is not sufficient enough to protect the HPFP.

 

I believe the secondary filter is 4 micron so should be fine on that count.

 

Now I don't know about the rest of the post, but this is completely incorrect. This engine was designed in Detroit, not Germany. Adam Gryglak was the chief engineer, and he came on here and answered some questions a year and a half ago near the launch date for the truck.

Check it out:

From HERE.

They did use things learned from other nations though:

From HERE.

To my knowledge the Super Duty isn't available anywhere other than North America with the exception for some export models sold without warranty. This is not a global platform.

On edit:


Correct, the engine-mounted filter is 4-micron.

 

Yes the 6.7 is designed and built by Ford with the help of a Austrian company called AVL . Ford 6.7L Powerstroke Diesel Engine - EGR Valve - Diesel Power Magazine

and it states it here to, AVL (engineering company) - Wikipedia, the free encyclopedia

 

That's exactly right.

But there's a HUGE difference between

and

It's one thing to have an Austrian(NOT German) company help with the initial design, and a completely other to have them design, test, and build the whole truck and then sell it over here.

Ford did take experience from everywhere when they designed this engine, and I believe that's why it's been as successful as it has.

After looking at it again, there are a few other items on it as well.

 

Although it is stated that fuel quality is critical, it mentions that you "can" add the additive. They don't state it is absolutely necessary. Not that you shouldn't use it... No one ever mentions specifically from Ford that you HAVE to like DEF.
