My 76 fuel gauge pegs to the full mark. The low fuel light works. New sender in the tank. The diagrams I found show the solid green wire to the spade terminal marked G. the other terminal is marked +. the diagram show a double ground. Any link to a different diagram or drawing would be great.

I don't exactly know how I fixed it but it now works! When I disconnected the ground wire from the brake warning light that also made the buzzer buzz continuously the fuel gauge started to work. Go figure.

The G stands for "Gauge" as in the signal wire from the tank sender. + is 12V switched power, and the brown wires are always negative to ground.

Sounds like you may have had a sender float stuck if the full position or the empty position and it got freed up. The good news is that it now works. I spent a few weeks without a fuel gauge and used an aluminum dipstick that I bead blasted so I could see the level in the tank / only ran out of gas once....... A good working gauge is much better..........

My gas gauge works (kinda). I re-set my odometer to zero whenever I fill up. When it gets close to 250 miles, I start thinking about filling up again. When it reads 300 miles I start to "seriously" think about filling up again.

Well that was short lived. It's back to full right peg. I must have a wire going to ground. No one said this restoration hobby would be easy.

I don't understand the issue. Sounds to me like you've got a full tank all the time.

Double brown should go to the terminal with the tiny nut (left terminal in the pic). Double red wire goes to the bottom terminal. Green wire goes to the top terminal.
