Answer
If I was doing the job I would locate the fuel gage feed wire near the fuel tank. In this car there is no electric fuel pump so there will be one or two wires going over the top of the tank. One will be feed and if there is a second wire it should be ground and colored black. Cut the feed wire. With the key on and a volt meter connected to the wire coming from the front of the vehicle there should be between 5 and 12 volts present. No voltage with the key off. Now with the key off ground the wire coming from the front with a jumper wire. Turn the key on and the fuel gage should start to climb towards full. If it does the front part of the system is ok the problem is in the rear, a bad sender or a bad ground.
