Instead of producing a stainless tank to make room for insulation, etc. as well as reducing the volume of the tank, have you considered installing a fuel radiator on the return line? Summit Racing has a dual pass radiator meant for this purpose. I have thought about using this myself, but like yourself, I am up to my throat with projects. I do not think that installing this would be too difficult other than locating a place to install it. You will obviously not install it behind the water radiator, so it would be necessary to locate a place where "clean" air could be easily directed to the cooling fins. This would allow you to not mess with fabricating a new tank, reducing the volume, and screwing with insulating everything. Just a thought. Sean Howley VIN#2345
