Fuel sender could have gone bad. It's in the tank.

Your low fuel light will normally come on with 2.1-2.6 gallons of fuel stillin the tank. Is it just on all the time??

You need to pull the tank to get to the sending unit. The sending unit is inside the gas tank.

Fuel pump sends gas to the engine. The sending unit tells the gauge how much gas you have. You may be able to access the sending unit from under the rear seat. (Not sure though, but most tanks do have the sender on the top.)
