Hello Herb. My name is***** rust can come from wherever you get your fuel from, the fuel sending unit will rust and drop into the bottom of tank.Then some old boats used galvanized fuel tanks. The galvanizing has long worn off and the tank is rusting internally. These are the ways rust gets in the fuel tank. Since you have allot we can eliminate the fuel sender. The place you purchase fuel can be eliminated if they have fiberglass or plastic tanks. Then finally the fuel tank is it metal? Are you sure it is rust and not algae? Post back with questions.
