Replace the gasket. Make sure both surfaces are clean and smooth. They get
old after a while. You can get gasket material at the auto parts store if
you can't find the gasket.

Have 100 gal fuel tank that was just topped off and fuel gauge sender
appears to be leaking. It appears to be the gasket and all screws are
tight. Any advise on repair would be appreciated.
