So I unscrewed and tilted the CC off the coffin cover over the fuel tank. Thankfully the last idiot (you'll find out why I call him that further in this reply) didn't 5200 down the cover, although he used a mixture of polyester resin and silicone. Apparently he was too lazy to clean and prep the surfaces which was good for me because it broke loose without too much swearing. The fuel sending unit, what was left of it, was installed exactly in the center on the top of the 40 gal. tank. The top plate of the sending unit was nothing but a pile of rust and there was a 1"hole. I was able to fish out the rest of the sending unit rheostat/ float assy. which turned out to be a Bosch automotive unit, not marine...AND it still worked when I tested it. There were exposed corroded wires where the leaking gas had dissolved the jackets of the non-marine thhn wires, 10 ga!) used to connect the ground and gauge. The leaking gas had also dissolved the jacket of the fuel hose down to the braid.
But I am ecstatic. Had it not been for the fuel gauge not working, I would not have discovered these until some catastrophic break down far from shore. The guy who sold me this boat obviously knew there was a leak but didn't tell me.
