how often??
so all of the latest news on here is about the hpfp and its failures. and like everyone else im worried about being a victom of a $10k bill that ford wont step up to take care of. some of you posted pics of ur fuel filters up on here and i saw the one that had metal fragments in it. so now im just wondering how often all of you are changing ur fuel filters and draining ur water seperator. i called my dealer and they said the fuel filters are good for 20,000 miles.. but i think im willing to change them more often now.

Everyone is welcome to do whatever they feel is best. I frankly enjoy maintaining my truck and do all my service more frequently than Ford recommends. So far however there is no information saying that changing fuel filters will help prevent HPFP failure or that there really even is a reason to worry about HPFP failure. You'll need to sort through the noise of the internet to figure out what reality is. If you make a few calls to a few dealer service departments, I'm willing to bet they will mostly state that the 6.7L is an incredibly reliable engine. Time is marching...

I am with Epic on this one ...changing the fuel filters every week will not stop the failures that we have been discussing...he is also correct that we need the march of time to truly isolate the real problem, if any, with the HPFP.
This in no way changes the facts that 520 scar fuel is not within the engineering specs that Bosch requires for long HPFP pump life...think of how much longer the pump would last if it ran in it's designed envelope.
Follow the maintenance schedule, use the fuel additive, feed it a little low % Biodiesel and enjoy the truck...it is what I do...

I agree with both Rickatic and Epic, I also tend to have a more aggressive maintenance schedule,,,but it has nothing to do with the claimed failures. I have talked with two different service departments in the Dallas area and neither tech knew of any failures and were very surprised to hear about the fears expressed on this forum. What they did express was the reliability of this engine,,,,time will tell.

I also agree.
If the metal is from the HPFP then changing filters isn't going to stop the metal.
If the pump explodes, it's going to destroy everything regardless.
Now if my filter change this weekend shows all the crud my last filter had, I'm probably moving to a 10k filter change from a 15k change.

The handy thing about adding a filter to the return line is that if that filter picked up metal flakes, then it is nearly certain that the HPFP is the source of the particles.

I checked with techs at BobTomes in McKinney and North Central in Richardson

I don't believe North Central sells a huge volume of diesels, however Bob Tomes does, I don't remember seeing any SD's there which were not diesels. Since you know about two I would find it hard to believe any diesel tech worth his salt in the same market would not know about it. Kinda ticks me off if they knew about the issue and did not disclose, maybe I am just too trusting.

I agree. Thats all I've heard about, misfuels (DEF/water/gas in the fuel tank). But according to everyone on here, they all should be covered under warranty.

I'm tired of wondering the answer to this question, so I'm just going to ask it. I've only personally put about 2000 miles on my truck, but it has 35k on it. I bought it with roughly 33k miles on it. I have drained the water separator a few times. I did it immediately upon purchase, once at 34k and again at 35k. Here is my question...I turn the yellow **** and let fuels drain into a container briefly (get maybe a cup of fuel) and then close the valve. I never see any water, nor do I see any in the container. However, just for grins I put a bit of water (like several drops in the cup) and then looked at the fuel and really could tell I added any water really. So how the heck do I know if I have any water in there or not? What am I looking for really?

If u drained the separator into see thru glass cup u will see little drops of water at the bottom of the cup if there was water in it. If u don't see any, take the cup with fuel in it and go to the sink and put a couple drops of water in the cup and watch the water sink to the bottom instantly
