Default Fuel gauge problem

I have a 30 gal Moeller fuel tank on my pontoon. When I got the toon out of storage the fuel gauge was pegged past full with no power on. I could not get the gauge to move no matter what I did. The resistance on the sending unit read .5 ohms empty and only1.5 ohms with the arm raised to the full position. the gauge remained pegged past full with the gauge out of the tank and disconnected. Could I have a bad gauge and sending unit?

Average reading range for a fuel sender is 40 to 240 ohms. With minimal reading you peg the gauge. Your sender is shorted. Replace it. If you gauge stays pegged with power of, it's defective.
