F 150 4WD Pickup V8-5.4L CNG VIN M (2001)
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 CAN 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 CAN OCCUR. THE RELEASE OF PROPANE FUEL IN A
CONFINED AREA CAN RESULT IN AN ACCUMULATION OF FLAMMABLE VAPORS. IF FUEL IS VENTED NEAR A HEAT SOURCE, A
FIRE OR EXPLOSION CAN OCCUR.
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.
Removal
1.
Relieve the fuel line pressure as follows:
^
Remove the fuel tank shield.
^
CNG: Disconnect the CNG fuel tank valve electrical connectors.
^
LPG: Close the fuel tank valve on the LPG tank.
^
Set the dash fuel selector switch to ALT and run the vehicle until the switch indicator lamp goes out.
2.
Install a memory saver, then disconnect the battery negative cable.
3.
On LPG vehicles only, drain the engine cooling system.
