Now this may seem like a stupid question but.......
You can buy XU-1 petrol tanks new, why not standard 10-gallon flat top fuel tanks? Not everybody wants the larger tank especially if your restoring a standard model.
Mine is rusted out on the top as most are, my other option is cut the top off and make a new top and weld it back together.
Does anyone know if someone out there is making new standard tanks?
