Hello to all. Mine had a hole worn through the underneath of that small part which jets out, over the pulley. This is/was common as the rear housing could not support the weight of passengers sitting on the rear rack. No amount of gas tank putty would fix it. Took the original tank to a local fabricator whom specializes in restaurant kitchen equipment. They made me a really nice unit out of thick stainless steel, without that small section to rub on the rear pulley. If I was to do it again, I would have had them weld an appropriate nipple on the bottom, instead of a plain tube. This way, a motorcycle petcock could be utilized to control the fuel supply. The entire cost for fabrication was less than $200 at that time. Good Luck!
