I bought the truck new, 2008 F350 diesel, the water in fuel light would come on all the time, I would keep draining it and when I took it in to have it checked they found no problems, I kept in serviced and changed out the fuel filters. The last time I changed the fuel filter the light quit coming on, with 8000 miles on the fuel filter the truck quit... Now they say it needs a new fuel system over$8000. and they will not fix it because it has to much water in the fuel and that is maintenance. What can we do????
