Ford F150 Pickup. Instruction - part 1183

 

 

inhaling propane gas, move the victim immediately to fresh air and 
contact a physician or medical emergency personnel for artificial 
respiration or other required treatment.

WARNING:

Do not needlessly vent propane fuel during service, and do not open the 
80% stop-fill valve while a vehicle is inside a building. When servicing the 
fuel system, follow the recommended procedures to shut off the fuel 
tanks and run the engine out of fuel before disconnecting the fuel system 
components. If the fuel tank(s) are being serviced, have the fuel 
evacuated by trained personnel at a local propane fuel station. Liquid 
propane fuel vaporizes at normal barometric pressure at temperatures 
above -42°C (-44°F), and expands to 270 times its volume as a liquid. 
Unnecessary venting of propane fuel can create fire and health hazards 
which could cause personal injury or death.

WARNING:

Be alert for situations that may cause the propane fuel system to vent 
fuel. These include extremely hot days, parking near a space heater, or 
hoisting a vehicle up near a ceiling heater. Release of propane fuel in a 
confined area through the pressure relief valve could occur. The release 
of propane fuel in a confined area could result in an accumulation of 
flammable vapors. If fuel is vented near a heat source, a fire or explosion 
could occur.

WARNING:

Do not use paint drying ovens for propane fueled vehicles. The heat of 
paint drying ovens will increase the pressure in the fuel tanks. This could 
cause venting of propane fuel vapor into the oven and result in a fire from 
the heat or sparks in the electrical equipment. If the fuel is confined inside 
an oven an explosion may occur. When refinishing the body panels of a 
propane fueled vehicle use spot painting and drying methods.

WARNING:

If a confined area, such as a lubrication pit, has been subjected to 
propane gas the area should be inspected for adequate oxygen levels by 
a local health department before being entered or personal injury or death 
may occur.

WARNING:

The fuel system pressure must be relieved before any component can be 
removed. The fuel tanks must be evacuated prior to tank removal. 
Removal of components without pressure relief or tank evacuation can 
cause propane fuel to escape into the air and cause injury or death.

NOTE:

In high ambient temperatures, such as those experienced in desert locations, 
the fuel system is designed to vent excess fuel vapor pressure. The pressure 
relief valve will vent fuel and automatically reset itself.

2. Disconnect the fuel line.  

3. Remove the nut, the washer and the fill valve. 

NOTE:

Use only new approved O-rings upon installation.

NOTE:

Lubricate the O-ring seals with Super Premium SAE 5W30 Motor Oil or 
equivalent meeting Ford specification WSS-M2C153-G.

Removal and Installation 

NOTE:

All fuel lines must be leak tested. Refer to LEAK TEST -- BI-FUEL 
SYSTEM .

WARNING:

Do not modify the system configuration or components or replace 
components with components no specifically designed for use with 
natural gas. Ford Motor Company has specifically designed the materials, 
components and system configuration for the 5.4L F-Series Bi-Fuel 
vehicle, and each particular system is precisely calibrated for efficient 
operation. The use of different parts or materials can produce an untested 
configuration that can result in fire or personal injury or cause engine 
damage.

1. Relieve the natural gas fuel system pressure. Refer to PRESSURE RELIEF -- NATURAL GAS BI-

FUEL SYSTEM . 

WARNING:

It is important that your bi-fuel vehicle be properly maintained by Ford bi-
fuel trained personnel. If a concern occurs, it is important that properly 
trained personnel diagnose the cause. If a concern relates to the fuel 
system, correct part replacement is imperative to keep your vehicle 
operating at normal performance. Bi-fuel components and gasoline 
specific components are not interchangeable. If your vehicle is not 
serviced in accordance with bi-fuel service procedures, damage can 
occur and your warranty may be invalidated.

WARNING:

Fuel supply lines are always pressurized. When servicing fuel related 
components, do not smoke or carry lighted tobacco or an open flame of 
any type. Flammable mixtures may be present and can ignite, resulting in 
personal injury.

WARNING:

The natural gas fuel system is always pressurized to 655 kPa (95 psi) 
downstream of the fuel pressure regulator and up to 24821 kPa (3600 psi) 
upstream of the fuel pressure regulator. Use care when servicing the fuel 
system or personal injury can occur.

WARNING:

The natural gas fuel supply manifold is pressurized to 655 kPa (95 psi). 
Fuel pressure must be relieved prior to any fuel system service.

WARNING:

The fuel system pressure must be relieved before any component can be 
removed. The fuel tanks must be evacuated prior to tank removal. 
Removal of components without pressure relief or tank evacuation can 
cause propane fuel to escape into the air and cause injury or death.

NOTE:

Use only new natural gas approved O-ring seals upon installation.

NOTE:

Lubricate the O-ring seals with Super Premium SAE 5W30 Motor Oil or 
equivalent meeting Ford specification WSS-M2C153-G.
