²Fuels can also be harmful if absorbed through the skin. If fuel is
splashed on the skin and/or clothing, promptly remove contaminated
clothing and wash skin thoroughly with soap and water. Repeated or
prolonged skin contact with fuel liquid or vapor causes skin irritation.
If you must replace the fuel filler cap, replace it with a genuine
Ford or Motorcraft part. The customer warranty may be void for
any damage to the fuel tank or fuel system if a genuine Ford or
Motorcraft fuel filler cap is not used.
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 system to work improperly in a collision, which may result in
possible personal injury.
Choosing the right fuel
At operating temperatures below 0ÉC (32ÉF), use a blend of No. 1D and
No. 2D Diesel fuels, also known as winterized No. 2D.
Do not use diesel fuel blended with waste oil in engines equipped with a
catalytic converter-muffler. Blending waste oil in with the fuel will plug
the catalytic converter-muffler, resulting in a significant loss of engine
power. Your emissions warranty will be voided if blending waste oil with
diesel fuel is practiced.
Use low sulfur (less than 0.05% by weight) fuel as required by the EPA
for emission compliance.
Do not mix diesel fuel with gasoline, gasohol or alcohol. This
could cause an explosion resulting in personal injury.
Do not use starting fluid such as ether or gasoline. Such fluids
can cause immediate explosive damage to the engine and
possible personal injury.
Maintenance and Specifications

Fuel filter replacementÐ7.3L Power Stroke engine
The fuel filter/water separator is
located on the right side of the
engine. Replace the fuel filter/water
separator as recommended in the
Scheduled Maintenance Guide, or
sooner if it becomes plugged.
Vehicles operated on fuel with more
than average impurities may require
replacement of the fuel filter more
frequently. The filter has a water
drain valve built into the bottom of
the filter housing.
Removal
1. Remove the fuel filter cap by
turning counterclockwise. The fuel
filter element will come out with the
cap.
2. Remove and discard the bevel gasket. Carefully clean the mating
surfaces.
3. Press in on the fuel filter element locking tabs to separate the element
from the cap.

Emissions control system(s) laws
Federal law prohibits vehicle manufacturers, dealers and other persons
engaged in the business of repairing, servicing, selling, leasing or trading
motor vehicles, as well as fleet operators from knowingly removing or
rendering an emissions control device or system inoperative. Further,
modifications of the emissions control system(s) could create liability on
the part of individual owners under the laws of some states. In Canada,
modification of the emissions control system could create liability under
applicable Federal or Provincial laws.
NOISE EMISSIONS WARRANTY, PROHIBITED TAMPERING ACTS
AND MAINTENANCE
On January 1, 1978, Federal regulations became effective governing the
noise emissions on trucks over 4 535 kgs. (10 000 lbs.) GVWR. The
following statements concerning prohibited tampering acts and
maintenance and the noise warranty are found in the Warranty Guide,
and are applicable to completed trucks.
Tampering with noise control system prohibited
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 presumed to constitute tampering are the following
acts listed:
Vehicle System Acts
Acoustical Shielding Removal of noise shields, hood blanket,
tunnel liner or acoustical absorptive
material.
Engine Removal or rendering inoperative the
engine speed governor so as to allow
engine speed to exceed manufacturer
specifications. Removal of engine mounted
noise shield or oil pan enclosure.
