Discovered yesterday that the base of my fuel tank around the seam has started to leak. This carry-on can is for my 57 Evinrude(origional) so I guess I can't complain to much however I was hoping that I could use a sealant like they use on car gas tanks. Has anyone had success with this approach? I would also like to replace the duel line fuel line but was told this line was hard to find.Any info.. would be appreciated.
