Stuff like this is why i just can't let go of my ol 7.3. I love the look of the new f-250's. mine hasn't even rolled 200k yet and it's an 03. I get the itch every now and again to go look at new ones and then i see a post like this one. Suddenly, that itch disappears.

7.3 is a good engine.

I haven't seen the 6.7 have any significant issues, on a large scale.
It is extremely quiet and fuel efficient. There is a ton of misinformation on the web and this thread is a prime example (exclusive of Downshift's posts).

Googling 6.7 problems shows some results, but nearly all the issues are on higher mileage examples with questionable maintenace practices.

That said, when they break, they will break you.

It's a lame excuse. No other engines are having rampant fuel pump failures due to ULSD being watered down.

And don't play the low lubricity card either. Old engines which weren't even designed with ULSD in mind are still ticking away on it.

Ford is trying to hide an issue with the design of the fuel system.

How rampant is the problem?

Honest question.


I wasn't referring to your posts. When I read stuff like the guy above me wrote, that has no basis in fact, it makes me .

Not very. I know several people with them and those are the only two I know of that grenaded personally.

That guy does run a fleet of them though and he's selling them all because somebody he knows had a few go out for the same issue. Ford claimed water in fuel on all of them.

Both of my buddies had to get entire new fuel systems. Both pumps, rails, injectors, etc because of corrosion and exploded stuff.

I think there is definitely a problem with the fuel system on those motors. Particularly the high pressure fuel pump.

Eta: or the fuel water separator. They might really be sucking up water.

Only telling you what the for dealer told me

I had 2 6.0's that blew up

I have a 2014 6.7
When I purchased it the only thing I knew about was some fuel problems

If I am wrong I apologize and stand corrected

I had a 2011. At 130k miles my high pressure fuel pump blew. $8500 repair. The more I searched for 6.7 fuel pump problems the more I found. It's starting to happen more frequently.

Mine did that. I had gone too far between oil changes (dealership said that anyway). I've got my doubts whether that was the case.

You were partially correct. One of my buddies burnt up ones did have severe corrosion on the PCV and VCV valves. I'm not entirely sure how ford arrives at the conclusion of water in fuel causing that, but whatever. I don't know that much about how that maze of an engine is put together.

Regardless of ford's logic, I've never heard of any diesel before the 6.7 blasting fuel pumps for water in fuel. Diesels have water separator and WIF sensors for a reason. Ford clearly has an issue somewhere between the tank and the injectors IMO.

This is my concern. As the trucks get higher mileage, we may see more problems crop up.

There is no basis in fact to say it is a rampant problem. I've seen a few threads, but nothing to indicate that has affected even 1% of the trucks sold.

The fuel filter should be changed every 22,500 or when you hear a noise behind the cab. That is key, and luckily it very easy to do.

I personally would change fuel filters every oil change.

You cannot be paranoid enough about fuel with an engine that runs 30,000+ psi injection pressure.

Probably not a bad idea and since oil change intervals are so long, it's not that big of a deal.

I'm still curious as to what maintenace is performed on some of these vehicles.

I went back and was trying to figure where I heard about the water in ULSD after earlier post
Then I recalled when I was looking at 6.7 I looked on powerstroke.org and saw most of that and dealer confirmed it about the 2011-2013 fuel system problems
They have a lot of people saying same thing on there
It may likely be Ford's way of getting out of warranty
Personally, if I didn't have to have the damn truck to pull, I would prefer a 150 with a gas engine
The two 6.0's I had ate a hole in my arse
And I am meticulous about maintenance

6.0 was a sorry motor.


If you are meticulous about maintenance, I doubt you'll have an issue with the 6.7.
Considering there are 500,000 6.7s installed, the odds are in your favor.

It definitely sounds like ford is using it as an excuse to not pay warranty claims.

They might not be though. There could be water in the fuel from a poor tank design allowing excessive condensation or something. It could be absolutely anything.

Be happy you never got sucked into a 6.4. As bad as the 6.0 was, the 6.4 was worse.
