The float sending unit is messed up and don't know now much gas is in the tank. The float may be stuck in a higher position showing more gas, in reality the gas level is way below. Try using a rubber mallet and tap on the gas tank near the fuel pump. It may help free up the float.
What you might have to do is check the gauges with a scanner.Not all scanners have this ability.The dealerships scanner can go into your body control module and work the gauges and if they work with the scanner then you can eliminate the gauge itself.The usual problem is with the fuel sending unit which incorporates the level sensor,pressure regulator,and the pump itself.So these are some of your options.Good luck.
i suspect a broken wire between guage and sender unit in tank, but the sending unit could be bad,find the wire to the float guage in the tank and disconnect it, if fuel level does not change then then touch the wire to a ground, if the guage changes then the wire is ok and the unit is bad, if it does not change check wiring and guage for faults.
You will need to locate the wire to the fuel sending unit at the fuel tank.
Once you locate the wire, disconnect it and see if the guage goes to 'E". If the guage goes to "E", you probably have a bad sending unit.
To double check, ground the same wire to clean metal on the frame with the key in the "on" position (not running). If the guage does not move, the guage is bad. If the guage moves from E to F, the sending unit needs to be replaced.
check the cable for the speedometer at the interconect. the cable is loose somewhere along the length of the cable. one back of he meter, 2, interconnect. 3, transmission case.
make sure the inner cable is square not rounded. if os, you need a new cable.
