    Leaking float

    Hiya folks,

    Is there any way to fix a leaking float? I have one float that continues to fill up with gas when it sits overnight. I tried to use a commercial fuel tank repair kit epoxy but even after it cured 24 hours, it melted (best way I can describe it) after being in fuel for a couple days, causing my float to sink... AGAIN. Can this be soldered, brazed, duct-taped, bubble-gummed??? Thank you so much.

    only sure way to fix it is to buy a new float really, or source a good second hand one
    1978 GS1085.

    Just remember, an opinion without 3.14 is just an onion!

      Is it a plastic or a metal float? if it is plastic then in theory once all epoxy is cleaned off, you could try and use a product like plastex to reseal it. If it is made from metal (likely steel or tin) then you should be able to solder/braze it to fix it up.

      Just remember to make sure all the residue of the epoxy is gone, lest it catch up in the plumbing and royally make a mess, especially if it manages to cure in there.

        Hi,

        If all else fails, partsnmore.com may have a float that's not too unreasonably priced.

        Thank you for your indulgence,

            I have three or four brass floats floating around (no pun intended). Do me a favor and measure the length of the pin runner (the tube the float pin goes through on the float) so I can be sure these will work for you.

            If they will, $10 shipped each to whomever needs em for as long as I have em.
