Ford F350 Dump Truck and Plow

This is a 1989 Ford Dump Truck with 8’ Hiniker plow. Overall the truck runs and drives great. New: radiator, hydraulic over electric power unit, front brake pads, rear brake lines, glow plugs, injector pump, batteries, engine block heater. I bought the truck with the plow but I have never had it on. It has all the attachments and electrical in the truck, but I cannot say that I used it. The guy I bought it from said it worked! The dump works great and the deck is in really good condition, (wood). Here is what it needs: Plastic fuel tank leaks, it leaked when I bought it and I tried to patch it but it started leaking about two months ago. Currently I put a pail under the tank and it drips about a gallon in about a week. The body is a wreck, seems every tine I use it more rust falls off. These old Ford Diesels had a problem with the oil pans rusting out. This one had a pin hole when I bought it and I patched it the last time I changed oil, leaks a little but not enough to be concerned. I still use the truck and just recently hauled six 3 ton loads of gravel and it drove and dumped perfect.
