Hi there,

I am looking at purchasing a 2008 6.4 diesel that has a problem because of water in the fuel.

Currently the vehicle does not run, worse case scenario, what am I looking at as far as repair cost? If I ran the diagnostic codes what codes would show up?

Thanks! Any reply is much appreciated.

water in the fuel and there selling it like that means they got a quote for a complete new system, probably $8000.

 

thanks. But cost aside specifically what problems will need to be fixed. Aside from the fuel line and fuel tank being flushed am I looking at a new fuel pump, injectors. Or would the damage have gone as far as pistons and cylinders?

Wouldn't at some point in time the computer have shut the truck down, sensing water in the fuel system.

What diagnostic codes am I looking for?

They got their insurance money and never had a specific diagnosis done.

 

The cost to the fuel system is basically everything, lines, injectors, pumps, tank should be OK. It should have gone into the limp mode, I would think the motor should be fine one never knows.

 

Pump, injectors, various lines, gaskets, fuel cooler, and probably some I'm missing. If the HPFP did in fact grenade, and you do the job per Ford guide lines, which is to pretty much replace the entire fuel system from the tank to the injectors you'd be looking at around 15K.

If the pump hasn't actually shredded itself you might get off quite a bit cheaper. The problem with a shredded pump is it sends metal particles down stream and makes everything "infected" either broken, or a ticking time bomb to brokesville.

If the factory water detector worked, it would have never gotten to the point it is. As far as I can tell it's a pretty much useless piece of tech that rarely works, mostly because the poor excuse for a water separator gets gunked up, passes water anyway, and the user never gets any indication.


Mine gave no indication of failure. Started it in my drive, got out to get some trash out of the garage, and within 30 seconds it had gone from smooth idle, to an engine that sounded like it was eating itself (starving injectors), to dead as a door nail.

I didn't even call Ford. I might have gotten it all covered under warranty, but had no interest in having them turn their wrench monkeys loose on my truck. I bit the bullet, hauled it down to Bulletproof Diesel in GA, and just under $7k later was a happy camper again. Them I have confidence in, Ford service garages I do not. They have proven too many times to not be worth the price of admission.
