The fuel sender unit is under the first aid box in the rear panel. Open the box, remove the kit and then remove the screws that hold the box in the rear deck and lift the box out. Once that is out you will see the top of the unit going down into the fuel tank. Disconnect the wiring plug and unscrew the big nut. You will need either a large socket or a large slip joint wrench that opens pretty wide. Remove the nut and pull the unit out.
