OK....the verdict is in............the radiator shop was able to "boil out" the tank and seal it with two coats of MAC's Antique Auto gas tank sealer. I've driven about 20 miles since the reinstall without even so much as a hick-up. The guy at the shop told me that he has been using the stuff for years without anyone reporting a problem. I'm goin to say it.......I'M OFFICIALLY BACK ON THE ROAD! Thanks for all the suggestions....another problem solved by the Stovebolters.
