Roadside emergencies

Observe the following guidelines when handling fuel:
²Extinguish all smoking materials
and any open flames before
fueling your vehicle.
²Always turn off the vehicle before
fueling.
²Automotive fuels can be harmful
or fatal if swallowed. If fuel is
swallowed, call a physician
immediately, even if no symptoms
are immediately apparent. The
toxic effects of fuel may not be visible for hours.
²Avoid inhaling fuel vapors. Inhaling too much fuel vapor of any kind
can lead to eye and respiratory tract irritation. In severe cases,
excessive or prolonged breathing of fuel vapor can cause serious
illness and permanent injury.
²Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes,
remove contact lenses (if worn), flush with water for 15 minutes and
seek medical attention. Failure to seek proper medical attention could
lead to permanent injury.
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.

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.

or (2) the use of the vehicle after such device or element of design has
been removed or rendered inoperative by any person.
