Good idea. I could probably ovalize some of the mounting holes and possibly get the tank to not rub against the exhaust. The opening of the trunk floor where the tank fits doesn't seem to allow for a lot of movement right or left though, it's a pretty tight fit. If not, break out the Big f'in hammer. I repainted my original tank and it's back in there and working great, so I probably won't revisit this for years to come if ever. Someone might get a really good deal (cheap) on a new tii gas tank at the Brisbane marina swap & show meet next year, we'll see ?
As far as paint goes. Krylon K09203007 'Rust Tough' Semi-Flat Black Rust Preventive Enamel - is a perfect match for the paint on the tank, ha ha! That's what I repainted my old tank in and also sprayed over the rub marks on the new tank. It matched perfectly.
