Youre gauge is controlled by a plunger in the fuel tank which is attached to the sensor and the fuel gauge. it sounds like when the plunger goes down half way its either getting stuck down lower then it should. Needs replacing. Any mechanic can do this install for you.

Tips for a great answer:
Instrument cluster indicator control
Fuel gauge control
Temperature gauge control
A/C compressor request
A/C cooling fan
Exterior and interior lighting control for the following lamps:
Daytime Running Lights (DRL)
Automatic lighting control
The Body Control Module (BCM) receives Class 2 serial data messages from the Powertrain Control Module (PCM) to determine the following gauge information:
Engine coolant temperature
Fuel level sensing
Your best bet is to take your vehicle to a qualified repair shop !
