What kind of problems are you having? If you are in need of a fuel tank (and are near Harrisburg, Pennsylvania) I know of at least 7 RC's in local salvage yards. May be able to locate one for you.
Mike the problems i am having is the straps are rusted out the whole assembly on top of the tank is rusted out and needs replacing if i have to i will replace the whole tank assembly and tank if can`t find parts if you see one that compatible. thanks again.
