Brought my f250 in to get some maintenance. Tranny fluid change, radiator fluid change and fuel filter change. The fuel filter was the one piece. So the top is attached to the filter. When I got home I looked under the hood and the top on the fuel filter was all dusty. Don't know how all the dust would be on there if it was just replaced. I called and they insisted they replaced. Hopefully the other services were done. Who knows. They seemed nice enough. But I can't be sure anything was done.
