Unless I missed Something .....What did you find on the old Tank? While the Job Klas233 did was Outstanding I'm not sure I like the idea of the tank being Supported by just the wood frame? The SS was a good Idea ...With Some of the Pounding my 311 takes I would want all the support I can get. Also the Original settup did last 28 years ......m

You can not use stainless steel for gas tanks. Have to use either allum., poly, or bladder.
That's not quite true - where I live insurance companies explicitly recommend using stainless steel over aluminum for gas tanks (and some even require it I believe).
