SERVICE RECOMMENDATIONS
Before you service yourBi-fuelvehicle, read and understand all
information found in theMaintenance and carechapter of your
Owner’s Guide and this supplement.
Refer to your scheduled maintenance guide for service requirements and
intervals.
Do not modify the gaseous fuel injection system configuration or
components. Do not replace the gaseous fuel injection system
components with parts not designed for use with your Bi-fuel vehicle.
Components designed for use in your CNG or LPG Bi-fuel vehicle
consist of special materials and are calibrated especially for your
vehicle. Failure to use the correct components may cause damage to
the engine and fuel system or possible personal injury.
Service to gaseous fuel injection system components must be
conducted only at qualified dealerships by qualified service
technicians. Failure to do so may cause damage to the engine and fuel
system components or possible personal injury.
Any modification to your Gaseous Fuel Injection System voids
the Ford New Vehicle Limited Warranty.
GASEOUS FUEL INJECTION SYSTEM SHUTOFF
When in the gaseous fuel mode under normal operating procedures, the
flow of CNG or LPG (depending upon application) is stopped when the
ignition is turned to the OFF position. The electrically operated control
valve(s) only allow the flow of fuel when the ignition is in the ON
position, with the engine running.
Liquefied petroleum gas (LPG)
If equipped with the manually-actuated supply valve(s), the flow of LPG
to the engine can be stopped by closing the supply valve located on the
LPG fuel tank(s).
If equipped, the manually-actuated supply valve(s) must be in the full
OPEN position for the engine to run on LPG.
Depending upon application, it may be necessary to remove an access
panel to close or open the supply valve(s).

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.
REFUELING STATIONS
To obtain a directory of all CNG refueling stations in the United States,
contact the American Gas Association (AGA) at 1–703–841–8400. In
Canada, contact Union Gas at 1–800–265–5277. For information on LPG
refueling stations, contact the U.S Dept of Energy Altertnative Fuels
Data Center at 1-800-423-1DOE (423-1363).
TANK INSPECTION AND REPLACEMENT
The fuel tank(s) of the Gaseous Fuel Injection System (CNG or LPG,
depending upon application) must be inspected and tested on a regular
basis to verify the condition of the tank(s).
Refer to your scheduled maintenance guide in your owner’s portfolio for
fuel tank inspection intervals.
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.

Liquefied petroleum gas (LPG)
For your protection, the LPG fuel tanksshouldbe visually inspected
every three years or 48 000 kilometers (30 000 miles) whichever comes
first. The purpose of the inspection is to check the tank(s) for damage or
excessive corrosion which may shorten the tank(s) usable life span.
All LPG fuel tank(s) used in Canada may require visual inspection every
five years. Contact the local authority governing the enforcement of
gaseous fuel regulations in the jurisdiction of which you refuel.
LPG fuel tanks that leak, show serious damage or excessive corrosion
mustbe repaired or replaced.
FUEL FILTER
YourBi-fuelvehicle is equipped with a separate fuel filter for the
gaseous fuel injection system. Its primary function is to remove
contaminants from the CNG or LPG fuel and trap it in the filter.
The fuel filter must be drained and/or replaced on a regular basis. Refer
to your scheduled maintenance guide for service requirements and
intervals.
Do not modify the gaseous fuel injection system configuration or
components. Do not replace the gaseous fuel injection system
components with parts not designed for use with your Bi-fuel vehicle.
Components designed for use in your CNG or LPG Bi-fuel vehicle
consist of special materials and are calibrated especially for your
vehicle. Failure to use the correct components may cause damage to
the engine and fuel system or possible personal injury.
Service to the gaseous fuel injection system components must be
conducted only at qualified dealerships by qualified service
technicians. Failure to do so may cause damage to the engine and fuel
system components or possible personal injury.
