Your sending unit has gone bad. Take it to a local repair shop or a dealership and they can replace it.

You can buy the sending unit by itself or you can buy it with a fuel pump as an assembly(means both come together). If you buy the assembly then it should fix any problems you have with the gas gauge.

Hope this helps!!
