AUXILIARY FUEL PUMP
The auxiliary fuel pump regulates the fuel supply to the FFBH. The pump is installed in a rubber mounting attached to the
chassis, below the RH front seat. The pump is a self priming, solenoid operated plunger pump, controlled by a Pulse
Width Modulated (PWM) signal from the control module in the FFBH. When the pump is de-energized, it provides a
positive shut-off of the fuel supply.
