Specifically, how does water in your fuel destroy the injection pump and the injectors? They're both fluids, so how does it happen?
18,000 sounds like they were gouging you and your insurance company. This happened to another member here also. The dealerquoted him around 12,000 bucks (which is extremely high also). I believe he repaired it for a lot less somehow.I got water in my fuel tank through the vents on top that didn't have hoses on them like they were supposed to and the truck completly laid down on me. Dealer pulled a gallon sample of fuel and got about 1 inch of water in the bottom. Found out that water was coming from the gooseneck pocket in the flatbed. Anyways got the insurance company to pay for it and they about s#$% when the bill was $18,000 to replace all injectors, injection pump and everything else that fuel touches. I asked about getting a new engine as it would be cheaper and would be happy to settle with a 5.9 but they didn't got for it. :CRY: No problems since just not happy with the truck at all.
