    Fuel Tank Don’ts

    I just wanted to share a bad experience I just had. While restoring my 1980 GS850GL I was working a rust inside the take. Now I think it’s important to know that the tank itself was in excellent shape; no leaks, no dents and no dings. Just needed the minor rust cleaned out of the inside and a fresh coat of paint. My plan was to soak the entire tank in a mild water/acid solution (25 to 1) and leave it for a day or two. Well, up popped an unexpected business trip and I’ll fast forward 3 WEEKS! After I returned and removed the tank from the solution, all the seams were eaten through with holes everywhere rendering the tank useless and unrepairable. Really makes me mad as I knew better.

    So, if anyone has a line on a decent fuel tank for a 1980 GS850 GLT, please contact me.

    What kind of acid were you using?

    I've used dilute phosphoric acid with good results. It attacks rust and leaves the base metal intact. Perhaps your tank was rusty inside on the seams and the acid removed enough of the rust so it started to leak.

    Some acids like HCL will cause metal to rust. Even the vapor can cause flash rusting if exposed to clean metal.

      I have a tank which I believe is from an 850L. Send a PM if you want it.


      Life is too short to ride an L.

        I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.
