I have an 05 Rubicon with about 8600 miles and I am having trouble with the fuel gauge. Sometimes the fuel gauge does not work. It will be completely full and the gauge will show it being as empty. If I turn the key off and back on, it will show the correct amount. Turn the key off and back on again, it will be showing empty. A couple of times the gauge would be flashing. Would this be a problem with the unit inside the tank or something electronic?
