G11310637

The Fuel Fired Booster Heater (FFBH) fuel pump is installed in a rubber mounting. The pump is a self-priming solenoid operated plunger pump. The FFBHCM outputs a Pulse Width Modulation (PWM) 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.
