you can loosen the plug where it goes to the fuel pump and take a test light to find out which one is the hot and ground for the pump,and the other one will be for the sending unit have some one set inside the vehicle and touch the wire to the wire then ground the other end of it out,if the hand is working right it will rise,and this will mean you need a sending unit,if not you have an open circuit between that part of the wiring and where it goes to the gage,it can take a while to find this if its not the sending unit,if you touch the right wire the gage will rise if its working right,good luck on it.

All you have to do is unplug the connector to the tank unit and turn the ignition on. The fuel gauge should go way over full. Now ground the pink wire to the connector on the side that leads to the forward of the truck. With the ignition still on the fuel gauge should go right to empty. These were famous for having poor sending units in the tank. Big job to do.

The sending unit is contained in the tank and confident you may could drop the tank to get at it. greater valuable nonetheless do not permit the tank get decrease than one million/4. as quickly as the gas point gets that low you danger choosing up sediment from the backside of the tank, and in case you reside in a cold climate you furthermore mght danger getting condensation contained in the tank that may freeze and block gas lines.
