•On F-Super Duty vehicles (6.4L engine),a frame-mounted
Horizontal Fuel Conditioner Module (HFCM)
•an engine-mounted secondary fuel filter
•a unit injector for each cylinder
The FCM/HFCM acts as a primary fuel filter/water separator which
removes both water and impurities from the fuel. The engine mounted
filter filters finer impurities from the diesel fuel. The engine-mounted
fuel filter and the FCM/HFCM filter should be changed at the
recommended service interval. Refer to thescheduled maintenance
informationin this supplement for more information.
F-Super Duty
E-Series
The FCM/HFCM should be drained at regular intervals or when the
WATER IN FUEL light illuminates in the instrument cluster.
The fuel injectors are located in the center of the combustion chambers
in the cylinder head between the rocker arm assemblies. The glow plug
system and fuel injection system are controlled through the Powertrain
Control Module (PCM) and Fuel Injection Control Module (FICM) (6.0L
engine only).
Fuel is drawn from the fuel tank by a frame-mounted electric fuel pump.
The fuel pump provides pressurized fuel to the engine and is
electronically controlled by the fuel pump PCM relay. The fuel pump
contains a pressure relief valve for overpressure protection in the event
of restricted flow.
Engine protection mode
Ford diesel engines are equipped with engine protection and emission
control systems. These systems monitor critical temperatures and
pressures, and modify engine operation accordingly. These features are
intended to modify engine performance characteristics. If these modified
engine performance characteristics persist for an extended period or the
service engine soon (
) or powertrain malfunction/reduced
power/electronic throttle control light (
) is illuminated, seek service
from your authorized dealer.

Glow plug pre-heat indicator:
With the key in the on position,
the
light will illuminate if glow
plug heat is necessary as a starting aid. Wait until the light goes off
before starting. Refer toCold weather startingin theDrivingchapter
of this supplement. After the engine starts, the light should turn on. The
light should always illuminate at least momentarily when the engine is
cold and the ignition is turned to on. If it does not illuminate, the glow
plug system should be checked and repaired promptly to avoid difficulty
in cold starting.
Water in fuel:
E-Series
F-Super Duty
During refueling, it is possible for water-contaminated diesel fuel to be
pumped into your tank. Your vehicle’s fuel system is equipped with a fuel
filter/water separator to remove water from the fuel. The WATER IN
FUEL light will illuminate when the ignition is turned to start (as part of
the light function check) and when the FCM/HFCM has a significant
quantity of water in it.
If the light illuminates when the engine is running, stop the vehicle as
soon as safely possible, shut off the engine, then drain the FCM/HFCM.
Refer toDraining the FCM/HFCM and changing the fuel filtersin the
Maintenance and Specificationschapter of this supplement for the
drain procedure. Allowing water to stay in the system could result in
extensive damage to, or failure of, the fuel injection system.
WARNING:Do not drain the water separator while the engine is
running. Fuel may ignite if the separator is drained while the
engine is running or the vehicle is moving.

Diesel fuel conditioner
Additives that will improve fuel cetane numbers may be used to
verify/enhance fuel quality. Use Motorcraft Cetane Booster &
Performance Improver, PM-22-A (U.S.) / PM-22-B (Canada) or
equivalent. The customer warranty may be void from using additives that
do not meet or exceed Ford specifications.
Do not use alcohol based additives to correct fuel gelling. This may
result in damage to the fuel injectors/system. Use Motorcraft Anti-Gel &
Performance Improver, PM-23-A (U.S.) / PM-23-B (Canada) or
equivalent. The customer warranty may be void from using additives that
do not meet or exceed Ford specifications.
Note:This ultra-low sulfur formulation is designed to meet the emissions
standards for the 6.4L engine and is backward compatible as well (i.e.,
can be used in Ford 6.9L, 7.3L, and 6.0L diesel engines).
Fueling tips
If the engine fails to start in 30 seconds, turn the key to the off position
and wait 30 seconds before trying again.
Truck stops have pumps and nozzles designed for larger, heavy-duty
trucks. When refueling at truck stops: if the nozzle shuts off repeatedly
when refueling, wait 5–10 seconds; then use a slower rate of flow (don’t
depress the nozzle trigger as far).
If air is allowed to enter the fuel system (during fuel filter change or if
you run out of fuel) the engine will purge the trapped air as it runs. The
engine may run rough and produce white smoke while air is in the
system. This is normal and should correct itself in a short time.
An engine that suddenly becomes noisy or operates poorly after a fuel fill
could be using substandard fuel (i.e., high water content, low cetane
rating or gasoline in the fuel). Diesel fuel should be purchased from a
reputable station which sells a large amount of diesel fuel.
Care should be taken whenever diesel fuel is stored. Use only clean,
approved containers which will prevent the entry of dirt or water.
Diesel fuel must not be stored in a galvanized container. The fuel will
dissolve the zinc in a galvanized container. The zinc will then remain in
the solution until it is run through the engine where it will be deposited
in the fuel injectors causing expensive-to-repair damage.
Diesel fuel dispensing nozzle fill rate
This truck is equipped with a fuel fill pipe which is able to accept fuel up
to 20 gallons per minute from an 1
1 8” fuel dispensing nozzle. Pumping
fuel at greater flow rates may result in premature nozzle shut-off or
spitback.
