Installation – Diesel Fuel Conditioner
Module filter
1.
Install the new filter into the filter bowl
tabs and replace the seal on the diesel
fuel conditioner module header (top
portion of separator). Refer to
Motorcraft part numbers in the
Capacities and Specifications chapter
for the fuel filter kit part number. See
Motorcraft Parts (page 55).
2. Lube O-ring with lubricant packet in the filter kit. This will assist in making
sure the filter is properly tightened. 3. Reinstall the lower portion of the
housing by slowly turning it clockwise
onto diesel fuel conditioner module
housing, allowing fuel to soak into the
fuel filter element. Tighten the lower
housing until it contacts the
mechanical stop.
Note: The engine will not run properly if you
do not install the diesel fuel conditioner
module fuel filter in the housing or if the
filter bowl is not tightened to the
mechanical stop.
Note: You will need to purge the system of
air after removal or changing of the filter.
See purging air from the fuel system later
in this chapter. Removal - Engine-mounted fuel filter
The engine-mounted fuel filter is a plastic
disposable cartridge. To remove it, do the
following:
1.
Disconnect both fuel lines by squeezing
the connector tabs and pulling the lines
straight off. Note:
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 a shop rag below
the filter connectors to absorb the small
amount of fuel that will drain.
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.

Diesel fuel dispensing nozzle fill rate
Your truck is equipped with a fuel fill pipe
that is able to accept fuel up to 20 gallons
per minute from an 11⁄8 fuel-dispensing
nozzle. Pumping fuel at greater flow rates
may result in premature nozzle shut-off or
spit back.
Fuel filler cap
WARNINGS
The fuel system may be under
pressure. If the fuel filler cap is
venting vapor or if you hear a hissing
sound, wait until it stops before completely
removing the fuel filler cap. Otherwise, fuel
may spray out and injure you or others. If you do not use the proper fuel filler
cap, excessive pressure or vacuum
in the fuel tank may damage the fuel
system or cause the fuel cap to disengage
in a collision, which may result in possible
personal injury. Note:
If you must replace the fuel filler cap,
replace it with a fuel filler cap designed for
your vehicle. The vehicle warranty may be
void for any damage to the fuel tank or fuel
system if the correct genuine Ford or
Motorcraft® fuel filler cap is not used.
Your fuel tank filler cap has an indexed
design with a 1/4 turn on/off feature.
When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise until it spins off.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the
cap with the notches on the filler pipe.
5. Turn the filler cap clockwise 1/4 of a turn until it clicks at least once. EMISSION CONTROL SYSTEM
Diesel Exhaust System: Oxidation
Catalyst And Diesel Particulate
Filter System (If Equipped)
Your vehicle is equipped with a diesel
particulate filter. The diesel particulate
filter is an inline filter in the exhaust system
that reduces carbon emissions by trapping
exhaust particles before they reach the
tailpipe. The diesel particulate filter looks
similar to a traditional exhaust catalyst,
except larger, and is part of the exhaust
system under the vehicle. The filter couples
to a diesel oxidation catalyst that reduces
the amount of harmful exhaust emitted
from the tailpipe. As soot gathers in the
system, it begins to restrict the filter. You
need to periodically clean the soot that
gathers inside the filter. You can clean the
soot in two different ways, passive
regeneration and active regeneration. Both
methods occur automatically and require
no actions from the driver. During either
one of these regeneration methods, you
may notice a change in exhaust tone. At
certain times, the information display will
display various messages related to the
diesel particulate filter. See the Information
Displays chapter in the Owner Guide for
more information.
Passive regeneration
In passive regeneration, the exhaust
system temperature and constituents
automatically clean the filter, or reduce
the soot level, by burning (oxidizing) the
soot. Cleaning occurs naturally because of
normal engine operating conditions (at
varying levels, due to driving patterns).

Emission Control System(s) Laws
WARNING
Do not remove or alter the original
equipment floor covering or
insulation between it and the metal
floor of the vehicle. The floor covering and
insulation protect occupants of the vehicle
from the engine and exhaust system heat
and noise. On vehicles with no original
equipment floor covering insulation, do not
carry passengers in a manner that permits
prolonged skin contact with the metal
floor. Provide adequate insulation. Failure
to follow these instructions may result in
fire or personal injury. In the U.S. federal law and certain state
laws prohibit removing or rendering
inoperative emission control system(s).
Similar federal or provincial laws may
apply in Canada. Ford recommends
against any vehicle modification without
determining applicable law.
Tampering with emissions
control systems (including
related sensors and the Diesel
Exhaust Fluid (DEF) injection system) can
result in reduced engine power and the
illumination of the service engine soon
light.
Tampering with a Noise Control
System
Federal law prohibits the following acts or
the causing thereof: (1) The removal or
rendering inoperative by any person other
than for purposes of maintenance, repair
or replacement of any device or element
of design incorporated into any new vehicle
for the purpose of noise control prior to its
sale or delivery to the ultimate purchaser
or while it is in use, or (2) the use of the
vehicle after such device or element of
design has been removed or rendered
inoperative by any person. Among those acts, which the U.S.
Environmental Protection Agency may
presume to constitute tampering are the
acts listed below:
•
Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer ’s
specifications.
The complexity of the diesel engine makes
it so the owner is discouraged from
attempting to perform maintenance other
than the services described in this
supplement.
If you experience difficult starting the
engine, rough idling, excessive exhaust
smoke, a decrease in engine performance
or excess fuel consumption, perform the
following checks:
• A plugged or disconnected air inlet
system or engine air filter element
• Water in the fuel filter and water
separator
• A clogged fuel filter
• Contaminated fuel
• Air in the fuel system, due to loose
connections
• An open or pinched sensor hose
• Check engine oil level
• Wrong fuel or oil viscosity for climactic
conditions
If these checks do not help you correct the
engine performance problem you are
experiencing, consult an authorized dealer.

4. Remove and install a new foam filter
if needed according to the service
interval indicated in the scheduled
maintenance information in this guide.
If you do not replace the foam filter, be
sure the existing foam filter is in place. 5. Install a new air filter element. Be sure
that the groove seal on the pleated
paper filter traps both sides of the
vertical partition of the air box. 6.
Replace the air filter housing cover and
secure all the clamps. Be careful not
to crimp the filter element edges
between the air filter housing and
cover. Ensure that you align the tabs
on the edge properly into the slots.
7. Reconnect the mass airflow sensor electrical connector to the inlet tube.
Make sure the locking tab on the
connector is in the locked position. Air Purge Procedure
Turn the key on for 30 seconds, and then
turn off. Repeat the procedure six times.
