fuel FORD F-350 2020 Service Manual

WARNING: 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. WARNING: 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 WARNING: 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.
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 you do not use the correct genuine
Ford or Motorcraft® fuel filler cap.
When fueling your vehicle:
1. Put your vehicle in park (P).
2. Switch the engine off. 3. Carefully turn the filler cap
counterclockwise until it spins off.
4. Pull to remove the cap from the fuel filler pipe.
5. To install the cap, align the tabs on the
cap with the notches on the filler pipe.
6. Turn the filler cap clockwise until it clicks at least once.
If the Check Fuel Cap light or a Check Fuel
Cap message appears in the instrument
cluster and stays on after you start the
engine, you may not have installed the fuel
filler properly.
If the fuel cap light 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
light or Check fuel cap 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.
REFUELING - DIESEL WARNING: Read and follow all the
instructions on the pump island. WARNING:
Stay outside your
vehicle and do not leave the fuel pump
unattended when refueling your vehicle. WARNING:
Keep children away
from the fuel pump. Never let children
pump fuel. WARNING:
Wait at least five
seconds before removing the fuel pump
nozzle to allow any residual fuel to drain
into the fuel tank.

WARNING: Do not remove the fuel
pump nozzle from its fully inserted
position when refueling. WARNING: 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. WARNING: 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. WARNING: 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.
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 you do not use the correct genuine
Ford or Motorcraft® fuel filler cap.
Fueling Tips
If air is allowed to enter the fuel system the
engine automatically purges any trapped
air. To purge the air sooner: prior to engine
start, prime the system by turning the key
to on for 30 seconds then to off. Repeat
this several times. The engine may run
rough and produce white smoke while air
is in the system. This is normal.
Use only clean, approved containers that
prevent the entry of dirt or water whenever
you store diesel fuel. Diesel fuel must not be stored in a
galvanized container. The fuel can dissolve
the zinc in the galvanized container. The
zinc then remains in the fuel. If you run the
contaminated fuel through the engine, the
zinc can deposit in the fuel injectors
causing expensive-to-repair damage.
Diesel fuel dispensing nozzle fill rate
Your vehicle has a fuel fill pipe that is able
to accept fuel up to
20 gal (76 L) per
minute from a 1.2 in (30 mm)
fuel-dispensing nozzle. Pumping fuel at
greater flow rates may result in premature
nozzle shut-off or spit back.
Truck stops have pumps and nozzles
designed for larger, heavy-duty trucks.
When refueling at truck stops: if the nozzle
shuts off repeatedly when refueling, wait
5– 10 seconds; then use a slower rate of
flow, do not depress the nozzle trigger as
far.
Refueling
When fueling your vehicle do the following:
1. Fully open the fuel tank filler door and remove the fuel tank filler cap.
Carefully turn the filler cap
counterclockwise until it spins off.
185
Super Duty (TFE), enUSA, Edition date: 201909, Third-Printing- Fuel and Refueling

2. Insert the fuel pump nozzle up to the
first notch on the nozzle A. Keep it
resting on the cover of the fuel tank
filler pipe opening. 3.
Hold the fuel pump nozzle in the lower
position B when refueling. Holding the
fuel pump nozzle in the higher position
A may affect the flow of fuel and shut
off the fuel pump nozzle before the fuel
tank is full. 4. When the pump shuts off, wait 5
seconds, then raise the fuel pump
nozzle and slowly remove it.
5. Replace the fuel tank filler cap and close the fuel tank filler door.
Note: Do not attempt to start the engine
if you have filled the fuel tank with incorrect
fuel. Incorrect fuel use can cause damage
that the vehicle warranty may not cover.
Have your vehicle checked as soon as
possible.
Dual Fuel Tanks (If Equipped)
Your vehicle may have a dual fuel tank
delivery system which operates
independently and automatically. The fuel
pump in the front fuel tank delivers fuel to
the engine. When the fuel level in the front
fuel tank drops below three quarter full,
fuel automatically transfers from the rear
fuel tank to the front fuel tank. Whenever
there is fuel in the rear fuel tank, the front
fuel tank level remains between half and
three quarter full.
Note: If your vehicle runs out of fuel, you
must add fuel to the front fuel tank to
restart the engine.

FUEL CONSUMPTION
Advertised Capacity
The advertised capacity is the maximum
amount of fuel that you can add to the fuel
tank after running out of fuel. Included in
the advertised capacity is an empty
reserve. The empty reserve is an
unspecified amount of fuel that remains
in the fuel tank when the fuel gauge
indicates empty.
Note:
The amount of fuel in the empty
reserve varies and should not be relied upon
to increase driving range.
Fuel Economy
Your vehicle calculates fuel economy
figures through the trip computer average
fuel function. See General Information
(page 109).
The first
1,000 mi (1,500 km) of driving is
the break-in period of the engine. A more
accurate measurement is obtained after
2,000 mi (3,000 km)
.
Impacting Fuel Economy
• Incorrect tire inflation pressures.
• Fully loading your vehicle.
• Carrying unnecessary weight.
• Adding certain accessories to your
vehicle such as bug deflectors, rollbars
or light bars, running boards and ski
racks.
• Using fuel blended with alcohol. See
Fuel Quality
(page 179).
• Fuel economy may decrease with lower
temperatures.
• Fuel economy may decrease when
driving short distances.
• You may get better fuel economy when
driving on flat terrain than when driving
on hilly terrain.

EMISSION LAW
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. Failure to
follow these instructions may result in
fire or personal injury.
U.S. federal laws and certain state laws
prohibit removing or rendering inoperative
emission control system components.
Similar federal or provincial laws may
apply in Canada. We do not approve of any
vehicle modification without first
determining applicable laws. Tampering with emissions
control systems including
related sensors or the Diesel
Exhaust Fluid system can result in reduced
engine power and the illumination of the
service engine soon light. Tampering With a Noise Control
System
Federal laws prohibit the following acts:
•
Removal or rendering inoperative by
any person other than for purposes of
maintenance.
• Repair or replacement of any device or
element of the design incorporated into
a new vehicle for the purpose of noise
control prior to its sale or delivery to
the ultimate purchaser or while it is in
use.
• The use of the vehicle after any person
removes or renders inoperative any
device or element of the design.
The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
• 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
specifications.
If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive
exhaust smoke, check for the following:
• A plugged or disconnected air inlet
system hose.
• A plugged 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.
• Incorrect engine oil level.
188
Super Duty (TFE), enUSA, Edition date: 201909, Third-Printing- Engine Emission Control

•
Incorrect fuel for climatic conditions.
• Incorrect engine oil viscosity for
climactic conditions.
Note: Some vehicles have a lifetime fuel
filter that is integrated with the fuel tank.
Regular maintenance or replacement is not
needed.
Note: If these checks do not help you
correct the concern, have your vehicle
checked as soon as possible.
Noise Emissions Warranty,
Prohibited Tampering Acts and
Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb
(4,536 kg) Gross Vehicle Weight Rating
(GVWR). The preceding statements
concerning prohibited tampering acts and
maintenance, and the noise warranty
found in the Warranty Guide, are
applicable to complete chassis cabs over
10,000 lb (4,536 kg)
GVWR.
CATALYTIC CONVERTER WARNING:
Do not park, idle or
drive your vehicle on dry grass or other
dry ground cover. The emission system
heats up the engine compartment and
exhaust system, creating the risk of fire. WARNING:
The normal operating
temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short
period of engine operation and stays hot
after the engine is switched off. WARNING:
Exhaust leaks may
result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes. WARNING: Do not allow people or
animals in truck beds that have
modifications, such as bed covers or
slide-in campers, when the engine is
running. Exhaust fumes are toxic. Failure
to follow this instruction could result in
personal injury or death.
Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable
exhaust emission standards.
To make sure that the catalytic converter
and other emission control components
continue to work properly:
• Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables. See Jump
Starting the Vehicle
(page 317).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note: Your vehicle warranty does not cover
resulting component damage.
The scheduled maintenance items listed
in scheduled maintenance information are
essential to the life and performance of
your vehicle and to its emissions system.
189
Super Duty (TFE), enUSA, Edition date: 201909, Third-Printing- Engine Emission Control

If you use anything other than our parts for
maintenance replacements or for service
of components affecting emission control,
such aftermarket parts should be
equivalent to our genuine parts in
performance and durability.
Illumination of the service engine soon
indicator, charging system warning light or
the temperature warning light, fluid leaks,
strange odors, smoke or loss of engine
power could indicate that the emission
control system is not working properly.
An improperly operating or damaged
exhaust system may allow exhaust to
enter the vehicle. Have a damaged or
improperly operating exhaust system
inspected and repaired immediately.
Do not make any unauthorized changes to
your vehicle or engine. By law, vehicle
owners and anyone who manufactures,
repairs, services, sells, leases, trades
vehicles, or supervises a fleet of vehicles
are not permitted to intentionally remove
an emission control device or prevent it
from working. Information about your
vehicle
’s emission system is on the Vehicle
Emission Control Information Decal
located on or near the engine. This decal
also lists engine displacement.
Please consult your warranty information
for complete details.
On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as the
on-board diagnostics system (OBD-II) that
monitors the engine ’s emission control
system. The system protects the
environment by making sure that your
vehicle continues to meet government
emission standards. The OBD-II system
also assists a service technician in properly
servicing your vehicle. When the service engine soon
indicator illuminates, the OBD-II
system has detected a
malfunction. Temporary malfunctions may
cause the service engine soon indicator to
illuminate. Examples are:
1. Your vehicle has run out of fuel —the
engine may misfire or run poorly.
2. Poor fuel quality or water in the fuel —the engine may misfire or run
poorly.
3. The fuel fill inlet may not have closed properly. See Running Out of Fuel
(page 183).
4. Driving through deep water —the
electrical system may be wet.
You can correct these temporary
malfunctions by filling the fuel tank with
good quality fuel, properly closing the fuel
fill inlet or letting the electrical system dry
out. After three driving cycles without these
or any other temporary malfunctions
present, the service engine soon indicator
should stay off the next time you start the
engine. A driving cycle consists of a cold
engine startup followed by mixed city and
highway driving. You do not require
additional vehicle service.
If the service engine soon indicator remains
on, have your vehicle serviced at the first
available opportunity. Although some
malfunctions detected by the OBD-II may
not have symptoms that are apparent,
continued driving with the service engine
soon indicator on can result in increased
emissions, lower fuel economy, reduced
engine and transmission smoothness and
lead to more costly repairs.

Readiness for Inspection and
Maintenance (I/M) Testing
Some state and provincial and local
governments may have
Inspection/Maintenance (I/M) programs
to inspect the emission control equipment
on your vehicle. Failure to pass this
inspection could prevent you from getting
a vehicle registration.
If the service engine soon
indicator is on or the bulb does
not work, your vehicle may need
service. See On-Board Diagnostics.
Your vehicle may not pass the I/M test if
the service engine soon indicator is on or
not working properly, for example, the bulb
does not work, or if the OBD-II system has
determined that some of the emission
control systems have not been properly
checked. In this case, the vehicle is not
ready for I/M testing.
If you have just serviced the vehicle ’s
engine or transmission or the battery has
recently run down or you have replaced it,
the OBD-II system may indicate that the
vehicle is not ready for I/M testing. To
determine if the vehicle is ready for I/M
testing, turn the ignition key to the on
position for 15 seconds without cranking
the engine. If the service engine soon
indicator blinks eight times, it means that
the vehicle is not ready for I/M testing; if
the service engine soon indicator stays on
solid, it means that your vehicle is ready
for I/M testing.
The OBD-II system checks the emission
control system during normal driving. A
complete check may take several days.
If the vehicle is not ready for I/M testing,
you can perform the following driving cycle
consisting of mixed city and highway
driving: 1. 15 minutes of steady driving on an
expressway or highway followed by 20
minutes of stop-and-go driving with at
least four 30-second idle periods.
2. Allow your vehicle to sit for at least eight hours with the ignition off. Then,
start the vehicle and complete the
above driving cycle. The vehicle must
warm up to its normal operating
temperature. Once started, do not turn
off the vehicle until the above driving
cycle is complete.
If the vehicle is still not ready for I/M
testing, you need to repeat the above
driving cycle.
SELECTIVE CATALYTIC
REDUCTANT SYSTEM - DIESEL
Your vehicle may have a selective catalytic
reduction system. The system helps 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.
Note: Selective catalytic reduction systems
are not fitted to vehicles in markets where
only high-sulfur diesel fuel is available.
Diesel Exhaust Fluid Level
In order for the system to operate correctly
you must maintain the diesel exhaust fluid
level.
A warning message appears in the
information display when the diesel
exhaust fluid level is low. If a warning
message appears, refill the diesel exhaust
fluid tank as soon as possible. See
Information Messages (page 120).
191
Super Duty (TFE), enUSA, Edition date: 201909, Third-Printing- Engine Emission Control

Only use diesel exhaust fluid that is
certified by the American Petroleum
Institute (API). Non-certified diesel exhaust
fluid use can cause damage not covered
by the vehicle Warranty.
Note:
Do not put diesel exhaust fluid in the
fuel tank. This can cause 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 fuel fill. The nozzle
shuts off automatically when the tank is
full. Do not continue to fill the tank as this
could cause spilling or overflow, potentially
damaging the tank.
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.
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 may freeze if the
ambient temperature is below 12°F (-11°C).
Your vehicle has a preheating system
which allows diesel exhaust fluid to
operate below 12°F (-11°C). If you do not
use your vehicle for an extended period
when the ambient temperature is below
12°F (-11°C)
, the fluid in the tank may
freeze. If the tank is overfilled and the fluid
freezes it may damage the tank. This is not
covered by the vehicle warranty.
Diesel Exhaust Fluid Warning
Messages and Vehicle Operations WARNING:
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, your vehicle
193
Super Duty (TFE), enUSA, Edition date: 201909, Third-Printing- Engine Emission Control

becomes limited to engine idle only once
stopped. In these conditions, be cautious
where you stop your vehicle because you
may not be able to drive long distances
or maintain highway speeds until you
refill or replace the diesel exhaust fluid.
WARNING: Tampering with or
disabling the selective catalytic
reduction system results in severe
vehicle performance limitation including
eventual speed limiting to
5 mph
(8 km/h).
The information display shows a series of
messages about the amount of diesel
exhaust fluid available. A systems check
displays messages indicating the amount
of diesel exhaust fluid available or displays
a warning message indicating the
approximate distance remaining as the
fluid in the diesel exhaust fluid tank nears
empty. See
Information Messages
(page 120). As the diesel exhaust fluid level
nears empty, the warning
symbol displays and a series of
tones and messages starting at
500 mi
(800 km) remaining before diesel exhaust
fluid is depleted. The warning symbol and
messages continue until you refill the
diesel exhaust fluid tank. Continued driving without refilling results
in the following actions as required by the
California Air Resources Board (CARB) and
the 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
refilling the diesel exhaust fluid tank
causes the engine to enter an idle-only
condition. This only occurs upon vehicle
refueling or at an extended idle. A
message indicates the required actions
to resume normal operation. It is
required to add a minimum of
1.0 gal
(3.8 L) of diesel exhaust fluid to the
tank to exit the idle-only condition, but
your vehicle is still in the speed-limiting
mode until you refill the tank
completely.
Note: For either vehicle speed limiting or
idle-only condition, normal vehicle operation
resumes when you refill the diesel exhaust
fluid tank.
Note: When filling the diesel exhaust fluid
tank from empty, there may be a short delay
before detecting the increased level of fluid.
The increased level detection must occur
before your vehicle returns to full power.
Diesel Exhaust Fluid Guidelines
and Information
• Use only diesel exhaust fluid that
carries the American Petroleum
Institute (API) certified diesel exhaust
fluid trademark or ISO 22241.
• Do not put diesel exhaust fluid in the
diesel fuel tank.
• Do not overfill the diesel exhaust fluid
tank.
• Diesel exhaust fluid is corrosive.
• Do not re-use the diesel exhaust fluid
container once it is emptied.
