Take the wire off the sending unit, and with the key in run and someone watching the fuel gauge, ground the wire. The gauge should swing full scale in one direction. Then take the wire off ground and let it touch nothing. The gauge should swing full scale the opposite direction. If this works, then the wiring and the gauge are ok, and there is something wrong with the sending unit inside the fuel tank. I believe the other poster is correct, the wire is going to be yellow/blue or blue/yellow.
