You could take the fuel pump connector loose, at the gas tank. In the diagram, the purple wire is voltage, gas gage, black wire is ground.
You could use a couple of different size resistors, between the purple wire and the black wire, key on, if gage reacts properly and steady to each resistor, I think the sending unit in the tank is faulty.
A 45 ohm resistor and a 90 ohm resistor should work ok. Radioshack sells resistors, they don't cost much.
