MOUNTED AND DIESEL FUEL
CONDITIONER MODULE FUEL
FILTERS - 6.7L DIESEL WARNING:
Do not dispose of fuel
in the household refuse or the public
sewage system. Use an authorized waste
disposal facility.
Your vehicle has two fuel filters. The first
filter mounts on top of the engine on the
left-hand side. The second filter is inside
the diesel fuel conditioner module. The
module is attached to the fuel tank in
different locations depending on the
configuration of your truck. See table
below for configurations.
Note: The module is at the front of the fuel
tank or at the front of the aft-axle fuel tank
on some models.
Regular fuel filter changes are an
important part of engine maintenance;
failing to keep with the scheduled
maintenance could lead to engine
performance issues and fuel injection
system damage. See
Scheduled
Maintenance (page 553).
Use only recommended service parts
conforming to specifications. See
Motorcraft Parts
(page 433).
Note: Using fuel that has high levels of
impurities may require more frequent filter
replacements than the service interval
specifies.

Removal 1. For 2017 models, disconnect the fuel
line quick connect coupling from the in
tank fuel pump. For 2018 models and
later, skip this step but insure that the
fuel filler cap is closed before draining
the filter. Failure to close the fill cap
results in the siphoning of the entire
fuel tank contents when you open the
drain screw.
2. Locate your filter.

Engine-mounted Fuel Filter
Although the fuel system is not fully
pressurized when the vehicle is off, some
residual pressure may remain in the fuel
system since it can take some time for the
pressure to completely bleed off.
Therefore, we recommend you place an
absorbent cloth below the filter connectors
to absorb any fuel that may drain.
The engine-mounted fuel filter is a plastic
disposable cartridge.
Removal
1.
Disconnect the fuel lines by squeezing
the connector tabs and pulling the lines
straight off. 2.
Rotate the filter fully counterclockwise
until the peg is at the far end of the slot.
3. Pull the filter straight up from the bracket and discard the filter.
Note: No special air purge is necessary after
filter servicing. The fuel system purges the
air in the filters.
Installation
1. Install the new filter into the filter bracket. Turn the filter clockwise to
lock it in place.
2. Reconnect the fuel lines.
3. Switch the ignition on for 30 seconds and then switch the ignition off.
Repeat this operation six times in a row
to purge any trapped air from the fuel
system.

CLEANING THE EXTERIOR
Wash your vehicle regularly with cool or
lukewarm water and a neutral pH
shampoo, we recommend Motorcraft
Detail Wash.
•
Never use strong household detergents
or soap, for example dish washing or
laundry liquid. These products can
discolor and spot painted surfaces.
• Never wash your vehicle when it is hot
to the touch, or during strong or direct
sunlight.
• Dry your vehicle with a chamois or soft
terry cloth towel to eliminate water
spotting.
• Immediately remove fuel spillages, bird
droppings, insect deposits and road tar.
These may cause damage to your
vehicle ’s paintwork or trim over time.
We recommend Motorcraft Bug and
Tar Remover.
• Remove any exterior accessories, for
example antennas, before entering a
car wash.
• When filling with AdBlue®, remove any
residue on painted surfaces
immediately.
Note: Suntan lotions and insect repellents
can damage painted surfaces. If these
substances come in contact with your
vehicle, wash the affected area as soon as
possible.
Cleaning the Headlamps
Note: Do not scrape the headlamp lenses
or use abrasives, alcoholic solvents or
chemical solvents to clean them.
Note: Do not wipe the headlamps when
they are dry. Exterior Chrome Parts
•
Apply a high quality-cleaning product
to bumpers and other chrome parts.
Follow the manufacturer ’s instructions.
We recommend Motorcraft Custom
Bright Metal Cleaner.
• Do not apply the cleaning product to
hot surfaces. Do not leave the cleaning
product on chrome surfaces longer
than the time recommended.
• Using non-recommended cleaners can
result in severe and permanent
cosmetic damage.
Note: Never use abrasive materials, for
example steel wool or plastic pads as they
can scratch the chrome surface.
Note: Do not use chrome cleaner, metal
cleaner or polish on wheels or wheel covers.
Exterior Plastic Parts
For routine cleaning we recommend
Motorcraft Detail Wash. If tar or grease
spots are present, we recommend
Motorcraft Bug and Tar Remover.
Stripes or Graphics (If Equipped)
Hand washing your vehicle is preferred

under the following conditions:
• Do not use water pressure higher than
2,000 psi (14,000 kPa)
.
• Do not use water hotter than
179°F
(82°C).
• Use a spray with a
40° wide spray
angle pattern.
• Keep the nozzle at a
12 in (305 mm)
distance and 90° angle to your
vehicle's surface.
