anyone ever made a new fuel tank for their M? i dropped mine(tank) to put in a new sender and there is a hole in the top of the tank from rust. the bottom of the tank is a bit beat up too. I work at a fab/ machine shop and can tig. i figured i would fix the hole in the stock tank for short term but take some dims and make up a stainless tank. maybe with extra capacity. bigger pickup line, and whatever bells and whistles i come up with. i happen to have plenty of ss sheet here on hand plus whatever i need from work. good idea?
