Gas gauge indicator on 2003 Mitsubishi Montero

My gas gauge indicator is stuck on 1/4. I am not sure if I need to change the fuel sending unit or a fuse. If the fuel sending unit, do I need to drop the gas tank or is there an eccess panel? Any insight would be great.

PULL OUT THE BACK SEAT AND THERE IS AN EASY ACCESS THERE. AND YES YOU NEED TO CHANGE THE SENSING UNIT.
