Up here in the salt belt we regularly rust the tank lines on the top of our American Holden Utes (that's a Chevy pickup truck) the guy at the local parts store sells a kit that has a tube that works like an electrical shrink wrap. I don't know if you have any fittings in the way but you can just slip the plastic tube over the metal and shrink it to fit with low heat. If that's an option let me know.
