bad news! i went to inlarge the bottom nipple of the fuel tank. i heated up a allen wrench and when i put it in, the nipple melted! so i just grinded and used a razor blade to remove it and make it smooth. i took off the metal nipple on top of the tank and screwed it in the bottom to see if it worked. it does from the looks of it. now i need another metal nipple for the top breather hole. i looked on ebay and they dont sell them individual. they only come with the tank. if anyone has a old fuel tank there not using, i need the metal nipple fitting. you could just put it in a envelope and mail it to me. i will pay you the $.42 for the stamp if you want. so please, if anyone has a metal nipple off a fuel tank, please let me know asap! thank you.
