Bill, this might be been caused by a peoprene washer being used behind the gauge. I had the same thing happen, and when I pulled the fuel gauge that neoprene gasket had turned to goo. After really cleaning out all of that old gasket material, I made my own gasket out of carburetor gasket material and used permatex on both sides when I re-installed the gauge.

I had to make my own tool to tighten that fuel gauge ring while holding the starred gauge in place with a flat piece of aluminum ground on both ends so it fit into the star.

Problem solved,

Mike
