I found the above bulletins for the fuel gage. Also, 40 ohms resistance, the gage should show full. 250 ohms resistance, the gage should show empty. If you use resistor on the proper terminals at the fuel pump connector, the gage should react accordingly, if it does, the problem is the tank sending unit.
