  • Nissan NS5B Internal Gas Tank Threads Stripped OFF!!?!!

    The tank threads are stripped and the cap won't seal. I understand this is a common problem. Anyone fixed this without buying a new tank? Can you use epoxy and the cap as a die to make new threads? Add an insert? Looking for ideas.

            The epoxy putty worked. First attempt was a failure as the epoxy wasn't hard enough. Second time I waited till the epoxy was 2/3 hardened and that did the trick. Cap seals fine.

              Should have pics of what they look like. I have a snowmobile with an oil tank and the cap would slip as if the threads were stripped. I took a copper plumbing cap (I think for 1 1/4 pipe) and cut the end off with a hacksaw. That left a copper ring about 1" tall. That ring just barely fit into the tank opening and supported the threads well enough for the cap to be put on very tightly. It has worked very well for over 5 years.
