Fuel Delivery Valve Assembly: Service Precautions
BI-FUEL MODELS
WARNING:
^
AVOID INHALING PROPANE GAS OR OCCUPYING CONFINED AREAS CONTAINING PROPANE. PROPANE IS HEAVIER
THAN AIR. THE HEAVIER GAS CAN DISPLACE OR PUSH FRESH AIR OUT OF AN AREA. IN LARGE QUANTITIES,
PROPANE CAN DISPLACE ENOUGH OXYGEN TO MAKE THE SURROUNDING AIR UNFIT TO BREATHE AND POSSIBLY
CAUSE ILLNESS. IF A PERSON BREATHES PROPANE GAS OR AIR THAT LACKS OXYGEN DUE TO THE PRESENCE OF
PROPANE GAS, HEADACHE, DIZZINESS, AND WEAKNESS IN THE EXTREMITIES CAN OCCUR. IN SEVERE CASES,
PROLONGED BREATHING OF PROPANE-FOULED AIR CAN CAUSE SUFFOCATION. IN THE EVENT OF ILLNESS FROM
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.
^
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.
^
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.
^
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.
^
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.
^
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.
^
USE NEW COPPER WASHERS ONLY; THE REUSE OF COPPER WASHERS MAY CAUSE SEALING ISSUES AND LIQUID
PROPANE GAS LEAKS IN THE ENGINE COMPARTMENT.
