Question for others out there. Just had my 08 F350 Diesel (73052 miles) serviced by my Ford dealer and they had to replace fuel pump and it was not covered by my warranty. They said that the cause was from bad fuel and Ford would not cover. So I call Ford customer service and they confirmed not covered. My dealer says it's a common problem in our area. I usually always buy my fuel at the same Chevron station that has a truck stop with it.

Want to know how often this is happening to others. I would think that Ford should have some kind of filter on the truck to prevent this problem. The repar cost $3,090--Ouch!!!

 

There are two filters on the truck. One down by the drivers side under the frame rail. A fuel water separator

The other on the engine.

If you don't know about this and the draining of the filters monthly then I suspect the issue really lies in lack of maintance with the possiblily of bad fuel.

Turn in a claim with Chevron and your insurance to recoup some of the cost.

 

This happened on my 2010. Dealer covered it under warranty. I did not know the repair was so costly! I was told it happens and sent on my way. I guess the best way to make these things last is to drain them monthly? I change the filters every 10k. No wif light has ever illuminated either. Only 45k on the truck too. Do these go every 40-50k? I'd think they'd be more resilient. IDK?

 

10K fuel filter changes and drain it monthly. Watch where you buy fuel.

They will last alot longer.

I have 81K and over 2100 hours on mine.

 

Thx Senix.
I've been spending most of my time in the 6.0l forum learning and fixing my 6.0l, never thought twice about the 6.4l....until that pump failed. I guess I have a lot more reading/learning about my 6.4 now. The truck runs amazing...it truly does. The guys on the 6.0 forum have got that engine figured out hands down. Gave me confidence in owning one. They're great. It's time to turn my attention to the 6.4... I'll read on and learn more. Thanks

 

Thanks for all the replies-- I'm aware of the way to drain the water on the bottom of the truck but can you please tell me how and where to clean/drain the one on the motor?

 

open the hood. there are canister filters there. One is oil, the other is fuel.

Takes the same 36mm socket as the rail one does.

 

I have a different perspective than Scott; the only way draining the water separator would have helped is if your water separator was overwhelmed by too much water. For that to happen you would have seen a "Water in Fuel" warning on your instrument panel. If you didn't see that I think it's unlikely that failure to drain your separator caused you any harm.

Bad fuel is bad fuel, and filtration can't always help that. Your primary filter screens out water from making it to the high pressure fuel system, and it also filters out damaging contaminants. But there are lots of other things that can mix with fuel that you simply can't filter out. You got fortunate because you didn't have to replace the entire high pressure fuel system; some unlucky owners have to fork over $10K for a new fuel system!

 

Interesting post...sounds like sometimes this water-in-fuel thing can be a crapshoot. I have 146k on my '09--also use an inbed aux tank for fuel on long trips. Never any problems--yet-- with the WIF separator. I change the filters at longer-than 10k intervals, but guess I need to pay more attention to mileage.
John Pulg--when purchasing the fuel filters, they both come in same box, so if you have it done, then both should be getting changed. There is no water drain on the upper filter, just pull the filter and see what is at the bottom of the housing. Clean carefully if needed. You also may have a wax buildup in the frame filter that needs to be addressed if you are not getting any water out when you use the drain valve. Lots of info on previous posts on here.
