FuelSender
Purpose
HowItWorks
Testing
The fuel sender uses an ultrasonic device that measures
the level of fuel in the fuel tank.
The sender measures the time it takes for and ultrasonic
signal to travel from the sender to the fuel in the fuel tank
and back to the sender to determine the fuel level (Fig.
501).
Apply 12 volts to the red lead, ground the black lead and
measure the voltage at the yellow lead.
The voltage should be between 0.5 volts (empty) and 4.5
volts (full).
Location
The fuel sender is located under the seat, on top of the
fuel tank (Fig. 500).
