I have a 2003 f-350 with the 6.0. Just recently purchased this truck, and when I changed the fuel filter, I cracked the fuel filter cap. Truck ran for a while, then lost power. I checked under the hood, and saw fuel coming from the top of the cap. I purchased a new cap, installed it, and the truck won't start at all. It acts as though it is trying to, but won't fire. Any ideas would be greatly appreciated!
