2016 FORD F750 fuel pump

To help achieve acceptable engine
performance and durability when using
biodiesel in your vehicle:
•
Confirm the biodiesel content of the
fuel to be B20 (20% biodiesel) or less
• Only use biodiesel fuel of good quality
that complies with industry standards
• Follow the recommended service
maintenance intervals. See
Scheduled Maintenance (page 314).
• Do not store biodiesel fuel in the fuel
tank for more than 1 month
• Consider changing brands or reducing
biodiesel content if you have cold
temperature fuel gelling issues or a
frequent LOW FUEL PRESSURE
message appearing
• Do NOT use raw oils, fats or waste
cooking greases
Use of biodiesel in concentrations greater
than 20% may cause damage to your
vehicle, including engine and/or exhaust
after-treatment hardware (exhaust
catalyst and particulate filter) failures.
Concentrations greater than 20% can also
cause fuel filter restrictions that may result
in a lack of power or damage to fuel
system components, including fuel pump
and fuel injector failures.
SAE 5W-40 or SAE 15W-40 oil is
recommended for fuels with greater than
5% biodiesel (B5). Refer to the Special
operating conditions section under the
Schedule Maintenance chapter for more
information about oil change intervals and
other maintenance when operating on
biodiesel. Look for a label on the fuel pump to
confirm the amount of biodiesel contained
in a diesel fuel. Biodiesel content is often
indicated with the letter B followed by the
percent of biodiesel in the fuel. For
example, B20 indicates a fuel containing
20% biodiesel. Ask the service station
attendant to confirm the biodiesel content
of a diesel fuel if you do not see a label on
the fuel pump.
Biodiesel fuels degrade more easily than
diesel fuels not containing biodiesel and
should not be stored in the fuel tank for
more than 1 month. If you plan to park or
store your vehicle for more than 1 month,
then you should empty your vehicle fuel
tank of biodiesel fuel. You should fill the
tank with a pure petroleum-based diesel
fuel and run your vehicle for a minimum of
30 minutes.
Note:
Degraded or oxidized biodiesel can
damage fuel system seals and plastics and
corrode steel parts.
During cold weather, if you have problems
operating on biodiesel, you may need to
use a diesel fuel with lower biodiesel
content, try another brand, or discontinue
the use of biodiesel.
Diesel Fuel Additives
It should not be necessary to add any
aftermarket additives to your fuel if you
use a high quality diesel fuel that conforms
to ASTM industry specifications.
Aftermarket additives can damage the fuel
injector system or engine.
Use Motorcraft® cetane booster or an
equivalent cetane booster additive if you
suspect fuel has low cetane. Use
Motorcraft® anti-gel & performance
improver or an equivalent additive if there
is fuel gelling.
94
F650750 (TBC), enUSA, First Printing Fuel and Refueling

Do not use alcohol-based additives to
improve cetane quality, to prevent fuel
gelling or any other use. The use of alcohol
additives may result in damage to the fuel
injectors and system. See Capacities and
Specifications (page 261).
The Vehicle Warranty may not cover
repairs needed to correct the effects of
using an aftermarket product that does
not meet Ford specifications in your fuel.
RUNNING OUT OF FUEL - 6.8L
Avoid running out of fuel because this
situation may have an adverse effect on
powertrain components.
If you run out of fuel:
• You may need to switch 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. When restarting, cranking time
takes a few seconds longer than
normal. With keyless ignition, just start
the engine. Crank time will be longer
than usual.
• Normally, adding 1 gal (3.8 L) of fuel is
enough to restart the engine. If the
vehicle is out of fuel and on a steep
grade, more than
1 gal (3.8 L) may be
required.
• The service engine soon indicator may
come on. See
Warning Lamps and
Indicators (page 58).
RUNNING OUT OF FUEL - 6.7L
DIESEL
Avoid running out of fuel as this allows air
to enter the fuel system, which makes
restarting your vehicle difficult. If your vehicle runs out of fuel:
•
If your vehicle is equipped with dual
fuel tanks, adding
4 gal (15 L) to 5 gal
(19 L) of fuel is enough to restart the
engine. If your vehicle is out of fuel and
on a steep grade, more than
4 gal
(15 L) to 5 gal (19 L) may be required.
• The fuel system must be primed before
attempting to restart the engine.
• Use caution not to overheat and
damage the starter by cranking the
engine for an excessive period. You
may need to crank the engine for a
longer time than normal. If the engine
fails to start in 30 seconds, turn the
ignition to the off position and wait for
two minutes before cranking the engine
again.
• Any remaining trapped air self-purges
from the fuel system once the engine
starts running.
• The engine may run rough and produce
white smoke while air is in the fuel
system. This is normal and should stop
after a short period.
Purging Air from the Fuel System
Turn the ignition key to on for 30 seconds,
then turn it to off. Do this six times in a row
to purge any trapped air from the fuel
system.
SELECTIVE CATALYTIC
REDUCTION SYSTEM
Your vehicle has a selective catalytic
reduction system to help reduce emission
levels of oxides of nitrogen from the
exhaust system. The system automatically
injects diesel exhaust fluid into the exhaust
system to enable correct selective catalytic
reduction system function.
95
F650750 (TBC), enUSA, First Printing Fuel and Refueling

Importance of Maintaining the
Diesel Exhaust Fluid Level
In order for the selective catalytic reduction
system to operate correctly the diesel
exhaust fluid level must be maintained.
A message appears in the information
display when the diesel exhaust fluid level
is low and needs to be refilled. When you
see a warning message, refill the tank as
soon as possible. See Information
Messages (page 64).
Filling the Diesel Exhaust Fluid
Tank WARNINGS
Make sure that diesel exhaust fluid
does not come into contact with
eyes, skin or clothing. Should any
diesel exhaust fluid contact your eyes,
flush them with plenty of water and
contact a physician. Clean affected skin
with soap and water. If any diesel exhaust
fluid is swallowed, drink plenty of water
and contact a physician immediately. Refill diesel exhaust fluid in a
well-ventilated area. When opening
the cap on the diesel exhaust fluid
tank or bottle containing diesel exhaust
fluid, ammonia vapors may escape. The
vapors can be irritating to skin, eyes and
mucous membranes. Inhaling ammonia
vapors can cause burning to the eyes,
throat and nose and cause coughing and
watery eyes. The diesel exhaust fluid tank has a blue
filler cap and the tank is behind the
left-hand front wheel. Fill the tank using a
fluid pump at a diesel exhaust fluid filling
station or a diesel exhaust fluid container.
We recommend Motorcraft® diesel
exhaust fluid, the containers are spill proof
and stop the flow of fluid when the tank is
full. See Capacities and Specifications
(page
256).

F650750 (TBC), enUSA, First Printing Fuel and RefuelingE210722 E163354)E163354

You must only use diesel exhaust fluid that
is certified by the American Petroleum
Institute (API). The vehicle Warranty does
not cover repairs resulting from the use of
non-certified diesel exhaust fluid products.
Note:
Do not put diesel exhaust fluid in the
fuel tank. This can cause engine damage
not covered by the vehicle Warranty.
You can purchase diesel exhaust fluid at
an authorized dealer, most highway truck
stops or you can contact roadside
assistance for help in finding a retailer that
sells diesel exhaust fluid. In addition, there
is a government website to help you find
the nearest location to purchase diesel
exhaust fluid:
http://www.discoverdef.com.
Filling the Diesel Exhaust Fluid Tank
Using a Fuel Station Pump
Filling the diesel exhaust fluid tank using
a nozzle is similar to a normal fuel fill. The
nozzle shuts off automatically when the
tank is full.
Filling the Diesel Exhaust Fluid Tank
Using a Container
The following procedure applies to
Motorcraft diesel exhaust fluid or similar
fluid containers. Always follow the
manufacturer's instructions.
1. Remove the diesel exhaust fluid container cap. Place the spout on to
the container and tighten it until you
feel a strong resistance.
2. Remove the diesel exhaust fluid tank filler cap.
3. Insert the spout in to the filler neck until
the seal on the spout seats on to the
filler neck. Pour the fluid in to the tank.
When the tank is full the fluid stops
flowing automatically. 4. Return the container to the vertical
position slightly below the diesel
exhaust fluid filler neck. Allow any fluid
remaining in the spout to drain back in
to the container.
5. Remove the spout from the diesel exhaust fluid filler neck. Replace the
diesel exhaust fluid tank cap.
6. Remove the spout from the diesel exhaust fluid container and replace the
cap.
7. Wipe away any diesel exhaust fluid that has spilled on painted surfaces
with water and a damp cloth.
Note: If there is diesel exhaust fluid left in
the container retain it for later use. The
spout is re-useable. Wash the spout with
clean water prior to storage. Do not use the
diesel exhaust fluid spout with any other
fluid.
Filling the Diesel Exhaust Fluid Tank in
Cold Climates
Diesel exhaust fluid freezes below 12°F
(-11°C); however, your vehicle has an
automatic heating system which allows
the diesel exhaust fluid system to operate
below
12°F (-11°C). When your vehicle is
not in operation for an extended period
with temperatures at or below 12°F (-11°C),
the diesel exhaust fluid tank could freeze.
Diesel Exhaust Fluid Warning
Messages and Vehicle Operations WARNINGS
Diesel exhaust fluid must be refilled
when low or replaced when
contaminated or your vehicle speed
becomes limited to 50 mph (80 km/h). In
these conditions, drive with caution and
refill diesel exhaust fluid immediately. If
the diesel exhaust fluid becomes empty
or contaminated and fluid is not replaced,
97
F650750 (TBC), enUSA, First Printing Fuel and Refueling

Continued driving without replacing diesel
exhaust fluid or having the selective
catalytic reduction system repaired results
in the following actions as required by the
California Air Resources Board (CARB) and
U.S. Environmental Protection Agency
(EPA):
•
Within a preset distance to empty,
speed is limited upon vehicle restart.
Prior to this occurring a message
appears in the information display.
• Further vehicle operation without
replacing contaminated diesel exhaust
fluid causes the engine to enter an
idle-only condition. This only occurs
upon vehicle refueling, vehicle idling in
park for 1 hour, or engine shutdown for
10 minutes or more and is indicated by
a message in the information display
indicating required actions to resume
normal operation.
Note: For either vehicle speed limiting or
idle-only condition, normal vehicle operation
resumes when you repair the contaminated
system. To service a contaminated or
inoperative system, see an authorized
dealer.
REFUELING - 6.8L WARNINGS
Fuel vapor burns violently and a fuel
fire can cause severe injuries.
Read and follow all the instructions
on the pump island.
When refueling always shut the
engine off and never allow sparks or
open flames near the fuel tank filler
valve. Never smoke or use a cell phone
while refueling. Fuel vapor is extremely
hazardous under certain conditions. Avoid
inhaling excess fumes. WARNINGS
Stay outside your vehicle and do not
leave the fuel pump unattended
when refueling your vehicle.
Keep children away from the fuel
pump; never let children pump fuel.
Wait at least 10 seconds before
removing the fuel pump nozzle to
allow any residual fuel to drain into
the fuel tank. Stop refueling after the fuel pump
nozzle automatically shuts off for the
second time. Failure to follow this
will fill the expansion space in the fuel tank
and could lead to fuel overflowing. Do not remove the fuel pump nozzle
from its fully inserted position when
refueling.
Use the following guidelines to avoid
electrostatic charge build-up when filling
an ungrounded fuel container:
•
Place approved fuel container on the
ground.
• Do not fill a fuel container while it is in
the vehicle (including the cargo area).
• Keep the fuel pump nozzle in contact
with the fuel container while filling.
• Do not use a device that would hold
the fuel pump handle in the fill position.
Fuel Filler Cap WARNINGS
The fuel system may be under
pressure. If you hear a hissing sound
near the fuel filler inlet, do not refuel
until the sound stops. Otherwise, fuel may
spray out, which could cause serious
personal injury.
100
F650750 (TBC), enUSA, First Printing Fuel and Refueling

1. When your vehicle has stopped, shift
into neutral (N) or park (P).
2. Apply the parking brake and switch the
ignition off.
3. Turn the fuel filler cap counterclockwise and remove it.
4. Refuel your vehicle as required.
5. Replace the fuel filler cap, turn it clockwise until you feel a strong
resistance.
If the fuel cap warning lamp or a warning
message appears in the instrument cluster,
you may not have installed the fuel filler
cap correctly.
If the fuel cap warning lamp remains on,
at the next opportunity, safely pull off of
the road, remove the fuel filler cap, align
the cap properly and reinstall it. The check
fuel cap warning lamp or warning message
may not reset immediately. It may take
several driving cycles for the indicators to
turn off. A driving cycle consists of an
engine start-up (after four or more hours
with the engine off) followed by normal
city and highway driving.
Fuel Fill Rate
Your vehicle has a fuel fill pipe that is able
to accept fuel up to 20 gal (75 L) per
minute from a fuel-dispensing nozzle.
Pumping fuel at greater flow rates may
result in premature nozzle shut-off or spit
back.
Truck stops have fuel pumps and nozzles
designed for larger, heavy-duty trucks. If
you are refueling your vehicle at a truck
stop and the nozzle shuts off repeatedly,
wait 5-10 seconds, then use a slower fill
rate. FUEL CONSUMPTION
Real world fuel consumption is governed
by many factors, for example driving style,
high speed driving, stop-start driving, air
conditioning usage, the accessories fitted,
payload and towing.
•
The usable capacity of the fuel tank is
the amount of fuel that can be added
into the tank after the gauge indicates
empty.
• The advertised capacity is the total fuel
tank size. See
Capacities and
Specifications (page 251). It is the
combined usable capacity plus the
empty reserve.
• Due to the empty reserve, you may not
be able to refuel the full amount of the
advertised capacity of the fuel tank
even when the fuel gauge reads empty.
Empty reserve is the amount of fuel
remaining in the tank after the fuel gauge
indicates empty. The amount of usable
fuel in the empty reserve varies and should
not be relied upon to increase driving range.
Filling the Tank
For consistent results when filling the fuel
tank:
• Turn the ignition off before refueling
your vehicle; a temporary inaccurate
reading may result if the engine is left
on when refueling your vehicle.
• Use the same fill rate
(low-medium-high) each time the tank
is refueled.
• Allow no more than two automatic
click-offs when refueling your vehicle.
Results are most accurate when the filling
method is consistent.

Note:
When you try to restart your vehicle
after a fuel shutoff, your vehicle makes sure
that various systems are safe to restart.
Once your vehicle determines that the
systems are safe, then your vehicle will
allow you to restart.
In the event of a moderate to severe
collision, your vehicle is equipped with a
fuel pump shut-off feature that stops the
flow of fuel to the engine. Not every impact
will cause a shutoff.
After an accident, if the engine cranks but
does not start, this switch may have been
activated. This switch is located on the passenger
’s
side of the instrument panel. Open the
front passenger door and remove the small
access panel. The switch has a red button on top of it. To reset the switch:
1. Turn the ignition off.
2. Check the fuel system for leaks.
3. If no leaks are apparent, reset the
switch by pushing in on the reset
button.
4. Turn the ignition on.
5. Wait a few seconds and return the key
to off.
6. Make another check for leaks.
Running Out Of DEF (Diesel
Exhaust Fluid)
If your vehicle runs out of DEF, it will enter
into a speed limited mode and can also
enter into an idle-only mode. Normal
vehicle operation will not resume until DEF
is refilled. See Selective Catalytic
Reduction System (page 95).
Contact roadside assistance for help in
finding a retailer that sells DEF. See
Customer Assistance
(page 156).
JUMP STARTING THE VEHICLE WARNINGS
Batteries normally produce explosive
gases which can cause personal
injury. Therefore, do not allow
flames, sparks or lighted substances to
come near the battery. When working near
the battery, always shield your face and
protect your eyes. Always provide correct
ventilation.
