fuel gauge flickering

my 96 town and country keeps losing its fuel reading. Driving down the road it will say 1/2 then drop to empty and the light comes on then goes back to 1/2. Any common wiring problems or just a bad sending unit?

Could be the sending unit or the wiring going to it. Could also be a bad ground. You can try grounding the tank with a jumper wire. Check the wiring going to the unit as well. You may even have to drop the tank to be able to check the wiring connector. Good luck
