Ford F-650/750 (2018 year). Manual - part 24

 

 

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 255).  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.

Calculating Fuel Economy

Do not measure fuel economy during the
first 900 mi (1,500 km) of driving (this is
your engine’s break-in period); a more
accurate measurement is obtained after
1,900 mi (3,000 km).

Fuel expense, frequency of fill ups or fuel
gauge readings are not accurate ways to
measure fuel economy.

1.

Fill the fuel tank completely and record
the initial odometer reading.

2. Each time you fill the fuel tank, record

the amount of fuel added.

3. After at least three fill ups, fill the fuel

tank and record the current odometer
reading.

4. Subtract your initial odometer reading

from the current odometer reading.

5. Calculate fuel economy by dividing

miles traveled by gallons used (For
Metric: Multiply liters used by 100, then
divide by kilometers traveled).

Keep a record for at least one month and
record the type of driving (city or highway).
This provides an accurate estimate of your
vehicle’s fuel economy under current
driving conditions.  Keeping records during
summer and winter will show how
temperature impacts fuel economy.  In
general, your vehicle will use more fuel in
cold temperatures.

Conditions That Affect Fuel Economy

Heavily loading your vehicle or towing
a trailer may reduce fuel economy at
any speed.

Carrying unnecessary weight in your
vehicle may reduce fuel economy.

Adding certain accessories to your
vehicle such as bug deflectors, rollbars
or light bars, running boards and ski
racks may reduce fuel economy.

Using fuel blended with alcohol may
lower fuel economy.

Fuel economy may decrease with lower
temperatures.

You will get better fuel economy when
driving on flat terrain than when driving
on hilly terrain.

Transmissions give their best fuel
economy when operated in the top
cruise gear and with steady pressure
on the accelerator pedal.

Close the windows for high-speed
driving.

FUEL TANK SELECTOR
SWITCH

 (If Equipped)

E205996

Your vehicle has two fuel tanks. The fuel
in each fuel tank is independently used.
Use the switch on the instrument panel to
select the left-hand or right-hand fuel tank.
The fuel gauge indicates the remaining fuel
in the selected fuel tank.  See Gauges
(page 56).

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.

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

WARNINGS

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.

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.

WARNINGS

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.

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 155).

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: Resulting component damage may
not be covered by the vehicle Warranty.

The scheduled maintenance items listed
in scheduled maintenance information are
essential to the life and performance of
your vehicle and to its emissions system.

If you use anything other than Ford,
Motorcraft or Ford-authorized parts for
maintenance replacements or for service
of components affecting emission control,
such non-Ford parts should be equivalent
to genuine Ford Motor Company parts in
performance and durability.
