You might have a poor ground path. The gauge reads empty at around 70 Ohm and full at around 15 Ohm. If you take off and short the sender wire for a couple of seconds you should see the gage rocket up.
If you have an open circuit you will see empty.
- poor ground - add a secondary ground from sensor to frame or preferbly to a black ground wire that is continuous to the back of the instrument cluster.
- duff sensor or one with the float full of petrol or sunk - best way to tell is to get a multimeter and measure the resistance at the sender.
