FUEL SUPPLY SYSTEM
Horizontal Fuel Conditioning Module
(HFCM)
• The HFCM is chassis mounted on CF500
and CF600 trucks. The module is mounted
on the inside of the left frame rail behind
the cab. The module is mounted with the
cover/mount facing the rail. The module
contains the fuel pump, fuel filter, WIF
sensor, heater and the recirculation control
valve. The water drain valve and all fuel
connections are mounted on the module
cover. The lower connection on the pump
end of the module is the suction side to the
tank and the lower connection on the filter
side is pressure to the engine-mounted
filter. The drain valve is accessible through
a hole in the frame rail.
Primary Fuel Filter and Fuel Heater
• The HFCM contains a 10-micron primary
fuel filter. The replaceable filter element
opens a fuel passage in the end of the
pump when the filter is inserted into the
housing. Without the filter in place,
sufficient fuel will not pass through the
system for correct engine operation.
• Fuel from the tank is exposed to the
electric fuel heater as it enters the HFCM
module. The heater is controlled by the key
switch start/run circuit and is self-
regulating. The heater comes on when fuel
temperature is below 50°F (10°C) and
goes off at 80°F (27°C). Return fuel from
the engine is recirculated to the suction
side of the filter until the fuel temperature
is sufficient to cause the recirculation valve
to close. After the valve closes, all returned
fuel is directed back to the tank.
