I replaced my fuel gauge sending unit with the Taiwan made aftermarket unit a few years back. Last year it stopped working and when I pulled it out I found that the float was full of gasoline. I emptied it and tried repairing it with JBWeld but a year later it is showing symptoms of the same problem.

According to cleanflametrap.com, this is a common problem but I haven't seen any recommendations for fixing it. I wish I would have kept my original sending unit as I would have just used the ball from it. The local junkyard doesn't have any sending units since the strip and crush all the gas tanks from the cars before putting them on the lot.

I saw a gas tank sealer product on the web from Caswell Inc. Anyone try using it to reseal a float?
