Compressed natural gas (CNG)
Use only a CNG fuel that meets the specification of NFPA-52 and SAE
J1616 in yourCNG Bi-fuelvehicle. Specifications NFPA-52 and SAE
J1616 place limits on particulate contamination and moisture content to
ensure a quality CNG fuel.
The use of a CNG fuel that does not meet specifications NFPA-52 and
SAE J1616 isnot recommendedand may cause engine damage.
Liquefied petroleum gas (LPG)
Use only an automotive grade LPG in yourLPG Bi-fuelvehicle.
Automotive grade LPG is typically referred to as HD-5 Propane and
contains at least 90% propane. Strict limits are placed on the amount of
other hydrocarbon gases which can be introduced into automotive grade
propane.
The use of an LPG fuel that does not meet the specification for HD-5
Propane (HD-10 Propane in California) isnot recommendedand may
cause engine damage.
REFUELING YOUR BI-FUEL VEHICLE
Refueling yourCNG or LPG Bi- fuelvehicle, with a few exceptions, is
very similar to refueling a standard unleaded gasoline powered vehicle.
Before refueling yourCNG or LPG Bi- fuelvehicle, be sure to read and
understandImportant safety precautionsin theMaintenance and
carechapter of your Owner's Guide and this supplement.
For safety reasons, use the same care and caution when refueling the
gaseous fuel injection system as you would when refueling the unleaded
gasoline fuel system. In particular, the enginemust always be turned
offwhen refueling.
DO NOT refuel your vehicle with the engine running or with the
ignition in the ON position. Failure to do so can be hazardous to
personal safety and property.
Some localities mandate a sticker be displayed showing the date of the
next required inspection. In localities requiring this sticker, refueling
station technicians arenot allowedto refill your gaseous fuel tank(s) if
the sticker is not visible or if the date has expired. For more information,
refer toTank inspection and replacementin theMaintenance and
carechapter of this supplement.

Many localities have restrictions on refueling CNG and LPG fueled
vehicles. In these localities, only qualified technicians at designated
refueling stations are allowed to refuel your vehicle. Refer to your
local authorized Ford dealer for more information.
Fuel fill procedure Ð compressed natural gas (CNG)
Two methods for filling the CNG fuel tank(s) are available toCNG
Bi-fuelvehicle owners:
²The fast-fill method Ð available at many of the commercial and
privately owned CNG refueling stations.
²The slow-fill method Ð available for purchase or lease from a number
of commercial or natural gas utility companies.
ªFast-fillingº aCNG Bi-fuelvehicle involves rapidly raising the pressure
in the vehicle's tank(s) by a ªfast-fillº refueling station (typical fill time:
3±5 minutes). ªFast-fillingº aCNG Bi-fuelvehicle provides the greatest
convenience to the driver in terms of time spent refueling.
ªFast-fillº refueling technology does not presently allow aCNG Bi-fuel
vehicle to be completely refueled to its maximum rated capacity.
Therefore, ªfast-fillingº results in a reduced driving range and an initial
fuel gauge reading of Full. However, within approximately 10 minutes,
the fuel gauge of aCNG Bi-fuelvehicle that has been ªfast-filledº will
drop about 1/8th of a tank lower to reflect the reduced amount of fuel
that was actually added.
ªSlow-fillingº aCNG Bi-fuelvehicle involves slowly raising the pressure
in the vehicle's tank(s) by a ªslow-fillº refueling station (typical fill rate:
6±8 hours). ªSlow-fillingº aCNG Bi-fuelvehicle usually is done
overnight and allows the greatest amount of CNG fuel to be added to a
CNG Bi-fuelvehicle. A properly functioning ªslow-fillº refueling station
will fill the CNG fuel tank(s) to a fuel gauge reading of Full at a
temperature of 21ÉC (70ÉF).
The CNG fueling point, or fuel receptacle is located on the driver's side
of the vehicle.
The profiles of both the CNG fueling point and the fuel station nozzle are
specified by ANSI/AGA NGV1-1994, CGA NGV1-M94. These profiles are
specified for CNG vehicles and fuel stations for safety purposes. Three
separate adapter profiles are available. P24, P30 and P36 respectively,
are specified for the three different service pressures of 16 500 kPa
(2 400 psi), 20 700 kPa (3 000 psi) and 24 800 kPa (3 600 psi).
Maintenance and care
25

Your vehicle's service pressure will be 24 800 kPa (3 600 psi).
Your vehicle's fuel system is rated at 24 800 kPa (3 600 psi); it can be
refueled using a P30 or a P36 nozzle only
Adapters for other types or styles of dispensing equipmentmust notbe
used.
When refueling, the enginemustbe shut off.
Use caution when refueling your vehicle. Make sure the engine is
turned off and all flammable material is extinguished. Observe all
Dispensing Equipment Safety Standards and Operating Procedures.
Use this procedure for both ªfast-fillº and ªslow-fillº CNG refueling.
1. Open the fuel filler door. Refer to the label on the inside of the fuel
filler door for the pressure rating of your vehicle's CNG fuel system.
²Look for one of these labels
(depending on application).
2. Remove the protective cap from
the vehicle's CNG fueling point.
Remove any debris that may be
present.
Maintenance and care

3. Follow the CNG fueling procedures provided by the natural gas dealer
and dispense the CNG until the fuel tank(s) are full or until the flow of
CNG stops.
4. When refueling is complete, follow the natural gas dispensing
equipment's operating procedures to shut the flow of natural gas off.
5. Remove the CNG dispensing connector and put the protective cap on
the vehicle's CNG fueling point. Close the fuel filler door.

Fuel fill procedure Ð liquefied petroleum gas (LPG)
Refueling aLPG Bi-fuelvehicle involves filling the vehicle's LPG fuel
tank(s) to the maximum limit of 80%. Refueling your LPG gaseous fuel
injection system is similar in terms of time spent refueling your unleaded
gasoline fuel system.
Your LPG Bi-fuel vehicle is equipped with an automatic stop-fill
device to limit the maximum LPG level in the fuel tank(s) to less
than 80%. Use of the 80% outage valve is required to prevent
overfilling of the LPG fuel tank(s).
Do not attempt to fill the LPG fuel tank(s) without opening the
outage valve. Use of the 80% outage valve is required to prevent
overfilling the LPG fuel tank(s). Failure to follow this warning may
cause damage to the engine and fuel system or possible personal
injury.
The LPG fueling point, or fuel receptacle is located on the driver's side of
the vehicle.
When refueling, the enginemustbe shut off.
Use caution when refueling your vehicle. Make sure the engine is
turned off and all flammable material is extinguished. Observe all
Dispensing Equipment Safety Standards and Operating Procedures.
Use the following procedure when refueling yourLPG Bi-fuelvehicle.

NOTE:LPG vehicles are typically fueled by the propane gas dealer not
the vehicle operator.
1. Locate and remove the protective
cap from the vehicle's LPG fueling
point.
2. Remove any debris that may be
present at the fueling point.
3. Open the outage valve.
Depending upon application, it may
be necessary to remove an access
panel to reach the outage valve.
Wear protective gloves when
operating the outage valve
to protect your hands from
possible freeze burns.
4. Follow the LPG fueling procedures provided by the propane gas dealer
and dispense the LPG until the fuel tank(s) are full or until liquid
propane spits out of the outage valve.
5. When refueling is complete, follow the propane gas dispensing
equipment's operating procedures to shut the propane gas flow off.
6. Close the outage valve. If
removed, replace the access panel.
Wear protective gloves when
operating the outage valve
to protect your hands from
possible freeze burns.

Charging the fuel lines of your LPG fuel system
The following procedure applies only to vehicles that are equipped with
LPG fuel tank(s) which have a manually-actuated supply valve.
If the fuel lines of your LPG fuel system have become empty due to
service or running out of LPG fuel, it may be necessary to ªchargeº the
fuel lines in order for the LPG fuel system to operate correctly.
Use the following procedure to ªchargeº the LPG fuel lines using the
manually-actuated supply valve(s), if equipped.
1. Turn the supply valve(s) clockwise to the fully CLOSED position.
²F-150
2. Wait for ten seconds for the excess flow valve (part of supply valve) to
reset.
3. Slowly turn the supply valve(s) counterclockwise to the fully OPEN
position and allow the fuel lines to fill with LPG.
²F-150
If the flow of LPG slows or stops before the fuel lines can be ªchargedº,
repeat the complete procedure.

FUEL DISPENSING EQUIPMENT
Most dispensing equipment will have a digital indicator that displays the
cost and amount of fuel delivered to your vehicle. Fuel delivery to the
vehicle is stopped when the amount of fuel stored on the vehicle reaches
the maximum refill pressure or quantity (depending upon application).
Certain noises can be expected during the refueling process and may
vary depending on the type of fuel dispensing equipment and your
proximity to the fuel compression and storage equipment. At the
beginning of refueling you might hear the rushing noise of gas entering
the vehicle through the station hose and tubing. At the end of refueling,
the fuel receptacle on the vehicle may make a high pitched noise or
chatter. This is another indication that refueling is nearly complete. Also,
the station dispensing equipment compressor may turn on at any time
during the refueling process.

fuel tank inspection intervals.
Maintenance and care
30

Inspection and testing of the fuel tank(s) must be done by a qualified
Ford service technician, or by the local authority governing the
enforcement of gaseous fuel regulations in the jurisdiction of which you
refuel.
Some localities mandate a sticker be displayed showing the date of the
next required inspection. In localities requiring this sticker, refueling
station technicians arenot allowedto refill your gaseous fuel tank(s) if
the sticker is not visible or if the date has expired.
Refer to the following for more information regarding gaseous fuel tank
inspection and replacement requirements.
Compressed natural gas (CNG)
For your protection, the CNG fuel tanks require visual inspection every
three years or 48 000 kilometers (30 000 miles), whichever comes first.
The purpose of the inspection is to check for damage to the fuel tank(s)
or tank wrap which may shorten the tank(s) usable life span.
CNG fuel tanks that leak or show serious damagemustbe repaired or
replaced.
The expiration date for the tank replacement is stated on each tank
label. See instructions on fuel container for inspection and service life.
Inspection and expiration dates for
the CNG fuel tank(s) are listed on
this label. Depending upon
application this label can be located
in the engine compartment, on the
fuel filler door and on the fuel
