2013 FORD SUPER DUTY open gas tank

IMPORTANT SAFETY PRECAUTIONS
WARNING:Do not overfill the fuel tank. The pressure in an
overfilled tank may cause leakage and lead to fuel spray and fire.
WARNING: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.
WARNING:If you do not use the proper fuel filler cap, excessive
vacuum in the fuel tank may damage the fuel system or cause
the fuel cap to disengage in a collision, which may result in serious
personal injury.
WARNING:Automotive fuels can cause serious injury or death if
misused or mishandled.
WARNING:Fuel ethanol and gasoline may contain benzene,
which is a cancer-causing agent.
WARNING:When refueling always shut the engine off and never
allow sparks or open flames near the filler neck. Never smoke
while refueling. Fuel vapor is extremely hazardous under certain
conditions. Care should be taken to avoid inhaling excess fumes.
WARNING:The flow of fuel through a fuel pump nozzle can
produce static electricity, which can cause a fire if fuel is pumped
into an ungrounded fuel container.
WARNING:Flexible fuel components and standard unleaded
gasoline fuel components are not interchangeable. If your vehicle
is not serviced in accordance with flexible fuel vehicles procedures,
damage may occur and your warranty may be invalidated.

Observe the following guidelines when handling automotive fuel:
•Extinguish all smoking materials and any open flames before fueling
your vehicle.
•Always turn off the vehicle before fueling.
•Automotive fuels can be harmful or fatal if swallowed. Fuels such as
gasoline and ethanol are highly toxic and if swallowed can cause death
or permanent injury. 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.
•Avoid 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.
•Avoid 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.
•Fuels 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.
•Be particularly careful if you are taking “Antabuse” or other forms of
disulfiram for the treatment of alcoholism. Breathing gasoline and/or
ethanol vapors, or skin contact could cause an adverse reaction. In
sensitive individuals, serious personal injury or sickness may result. If
fuel is splashed on the skin, promptly wash skin thoroughly with soap
and water. Consult a physician immediately if you experience an
adverse reaction.
•FFV fuel tanks may contain zero to 85% ethanol. Any fuel blends
containing gasoline and ethanol should be treated the same as “Fuel
Ethanol.” To identify if your vehicle is an FFV, it may be equipped
with a yellow fuel cap with the text “E85/Gasoline”, or check if there
is a label on the fuel filler door.
Pure ethanol is the alcohol which is the intoxicating agent in liquor, beer
and wine. It is distilled from the fermentation of plants such as field corn
and sugar cane. When ethanol is produced for use in motor fuels, a small
amount of gasoline is added to make it unfit for beverage use. The
resulting ethanol blend is called denatured fuel ethanol meaning that it is
denatured with 2% to 5% gasoline and is suitable for automotive use.

Octane Recommendations
Regular unleaded gasoline with a
pump (R+M)/2 octane rating of 87
is recommended. Some stations
offer fuels posted as Regular with
an octane rating below 87,
particularly in high altitude areas. Do not use fuels with a posted octane
rating below 87.
Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily under most driving conditions while you are using fuel
with the recommended octane rating, see your authorized dealer to
prevent any engine damage.
RUNNING OUT OF FUEL
Avoid running out of fuel because this situation may have an adverse
effect on powertrain components.
If you have run out of fuel:
•You may need to cycle the ignition from off to on several times after
refueling to allow the fuel system to pump the fuel from the tank to
the engine. On restarting, cranking time will take a few seconds longer
than normal.
•Normally, adding 1 gallon (3.8L) of fuel is enough to restart the
engine. If the vehicle is out of fuel and on a steep grade, more than
1 gallon (3.8L) may be required.
•
The service engine soon indicator may come on. For more information on
the service engine soon indicator, refer to theInstrument Clusterchapter.
SeeSettingsin theInstrument Clusterchapter for information on
calculating DTE (Distance to empty).
Refilling With a Portable Fuel Container
WARNING:Do not insert the nozzle of portable fuel containers
or aftermarket funnels the fuel system. This could damage the
fuel system and its seal, and may cause fuel to run onto the ground
instead of filling the tank, which could result in serious personal injury.
WARNING:Do not try to pry open or push open the fuel system
with foreign objects. This could damage the fuel system and its
seal and cause injury to you or others.
