I have always found that most small engine shops have a graveyard full of spare parts from models that were deemed not worth fixing, the last time I needed a metal gas tank for a generator that is where I found mine when a new one couldn't be found.I am looking for a B and S Fuel Tank, OEM part #297257. I am even open to good used. This is an old 70's engine, but runs great. Gas Tank rusted through.
