The sender is a float operated rotary potentiometer
which provides a variable resistance to ground for the
output from the gauge. When the sender float is at its
lowest point, indicating an empty fuel tank, the
resistance to earth is at its lowest. The resistance is
sensed by the gauge which positions the needle
accordingly.
Use ohm-meter to confirm that the resistance of the
fuel level sensor (Fuel Tank Unit) changes with the level
of float position.
