Then the green wire(s). One coming from back and one going out. I have to trace these tomorrow, but am I correct in assuming that one heads to the engine or battery, the other to the fuel cap bracket? I have to open it up tomorrow... but I'm pretty sure the green one does NOT go to a neg terminal on a battery. Not sure about the ground on fuel cap bracket.
Its driving me nuts!!!

You need to ground the tank to the neg bus.
Test by jumping a wire from the tank to neg. Your gauge will probably work.
I just chased this down on my boat the ground of the tanks were off and fallen down and hidden.
