warning FORD F150 2003 10.G Bi Fuel Supplement Manual

ABOUT THIS SUPPLEMENT
This booklet supplements your Owner’s Guide and is part of the owner’s
portfolio. It describes the operation of yourBi-fuelvehicle and how it
differs from a standard gasoline powered vehicle. Therefore it is very
important that you read this guide and thoroughly familiarize yourself
and others operating the vehicle with this information.
Some of the information in this supplement replaces certain instructions
in the Owner’s Guide. Please read this supplement carefully and
completely. Refer to the Owner’s Guide for complete vehicle information.
WARNINGS
Warnings remind you to be especially careful in those areas of the
vehicle where carelessness can cause damage to your vehicle or possible
personal injury to yourself, your passengers or others. Please read all
warnings carefully.

ABOUT THE WARRANTIES
The normal vehicle warranties will apply to yourBi-fuelvehicle. For
further information, refer to your Warranty Information Booklet in the
owner’s portfolio.
Specified maintenance procedures must be followed. Repairs must be
made by trained personnel.
It is important that yourBi-fuelvehicle be properly maintained by
qualified Ford service technicians. If a concern occurs, it is important
that properly trained personnel diagnose and repair the cause. If the
concern relates to the fuel system, proper part replacement is imperative
to keep your vehicle operating correctly.Bi-fuelcomponents and
standard fuel components are not interchangeable. If yourBi-fuel
vehicle is not maintained in accordance with approved service
procedures, damage may occur and your warranty may be invalidated.
GASEOUS FUEL INJECTION
YourBi-fuelvehicle is equipped with two fuel injection systems, an
unleaded gasoline fuel system and a gaseous fuel injection system.
Two types of gaseous fuel injection systems are available:
•Compressed Natural Gas (CNG)
•Liquefied Petroleum Gas (LPG)
Introduction
2

Labels similar to these are located in
the engine compartment and
contain diagnostic information for
your gaseous fuel injection system.
Compressed natural gas (CNG)
This label is located on the right
rear of your vehicle and identifies
the vehicle as using compressed
natural gas (CNG) as a fuel.
This warning label is located in the
engine compartment to help ensure
safe and proper maintenance of the
CNG fuel system.
Introduction
8

This label is located in the engine
compartment and on the CNG
tank(s) and lists the inspection and
expiration dates for the CNG fuel
tank(s).
Liquefied petroleum gas (LPG)
This label is located on the right
rear of your vehicle and identifies
the vehicle as using liquefied
petroleum gas (LPG) as a fuel.
This warning label is located on
either the driver’s side sun visor or
on the dashboard to help inform you
of cold weather operating conditions
when using LPG as a fuel.
This warning label is located in the
engine compartment to help ensure
safe and proper maintenance of the
LPG fuel system.
Introduction

The vehicle’s fuel system will NOT automatically change to the
gaseous fuel mode (CNG or LPG , depending upon application), if
the level of the unleaded gasoline runs low.
FUEL GAUGE
The fuel gauge in your CNG or LPGBi-fuelvehicle (depending upon
application) behaves similarly to a standard gasoline fuel gauge. The fuel
gauge will provide a linear reading from Full down to Empty.
•Fuel gauge operation for aLPG Bi-fuelvehicle is based on a float
type sensor measuring the level of the liquid propane in the fuel
tank(s).
•Fuel gauge operation for aCNG Bi-fuelvehicle is based on the
pressure and temperature of the natural gas in the fuel tank(s).
Depending upon the application, a full fuel gauge reading will occur at
a pressure of approximately 20 700 kPa (3 000 psi) or 24 800 kPa (3
600 psi) at a temperature of approximately 21°C (70°F). For more
information on fuel gauge performance during the fast-fill method of
CNG fueling, refer toRefueling your Bi-fuel vehiclein the
Maintenance and carechapter of this supplement.
WARNING LIGHTS
With the engine running, the“Check Engine/Service Engine Soon”
indicator light (depending upon application) will illuminate on the
instrument cluster when the On Board Diagnostics System and/or the
Gaseous Fuel Injection System detects a malfunction in one of the
engine’s emission controls. For more information, refer toWarning light
and chimesin theInstrumentationchapter of your Owner’s Guide and
this supplement.
If a malfunction of the LPG Gaseous
Fuel Injection System is detected
with the engine running in the
gaseous fuel mode, the green
indicator light on the fuel selector
switch will flash on and off.
The warning lights may illuminate or flash on and off (depending upon
application) without a driveability concern being noted. The vehicle will
usually be drivable and will not require towing. Contact a qualified Ford
dealership at the first available opportunity.

Fuel fill procedure — 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.
