Some people have had some success putting a 20 ounce bottle of the Techron Fuel System Cleaner in about an 1/8 tank of fuel in hopes of freeing/cleaning the fuel level sensor's pivot/arm.
IF you are going to bother to actually drop the tank (MAJOR pain), I would replace EVERYTHING else under there at the time (WHOLE fuel pump assembly {Delphi makes the best for OEM/stock power levels}, fuel pressure regulator, EVAP canister, etc.), not just the level sensor/float/arm.
AND flush out the tank with a plastic friendly solvent.
It is that much of a PIA.
