If I am understanding you correctly and the gauge works when you probe the yellow wire of the guage and ground it, then you are not getting a good ground on your gauge, a common problem with older cars because of the corrosion.

Do the same at the fuel tank, if results are the same it's a bad sender (use the test light clip grounded to the tank)

If the result isn't the same move the test light ground to the chassis, if results are same this would condemm the tank ground.

If the result isn't the same check the wire from the gauge to the tank for continunity.
