Leaky fuel tank at sender..

Had the same problem, here's what I did. The small tanks on the tank are usually ben ourwards. Take some time to gently tape them back into place. The next thing I did was to use brake fluid on the gasket. Does two things. lubes then rubber seal to ease installing the ring and after some time the rubber will swell from the brake fluid. Just an FYI. There was a member here that was selling NOS gas snder rings. Bought two for myself. He may have some more.
