Fuel Fired Booster Heater Fuel Pump

G11701570

The Fuel Fired Booster Heater (FFBH) fuel pump is installed in a rubber mounting attached to a cross-member under the rear floor, above the fuel tank. The pump is a self priming, solenoid operated plunger pump. The Fuel Fired Booster Heater Control Module (FFBHCM) in the FFBH outputs a PWM (Pulse Width Modulation) signal to control the operation of the pump. When the pump is de-energized, it provides a positive shut-off of the fuel supply to the FFBH.
