HEATER HOSE MAY BE INCORRECTLY ROUTED.

RiskHOSE COULD WEAR THROUGH AND LEAK WHICH COULD RESULT INAN UNDERHOOD FIRE.

FixREROUTE AND REPAIR HOSE AS NECESSARY.

EXTREME OPERATING CONDITIONS COULD CAUSE PREMATURE DETERIORATION OF THE ENGINE COMPARTMENT HEATER HOSES OR ENGINE BYPASS HOSES.

RiskENGINE COOLANT COULD DISCHARGE ONTO THE ENGINE AND ITSEXHAUST MANIFOLD CREATING THE POTENTIAL FOR A FIRE DUE TO THE HIGH ENGINEEXHAUST MANIFOLD TEMPERATURES.

FixREPLACE HOSES AND RADIATOR CAPS; INSTALL HIGH HEAT RESISTANCE ALUMINIZED STAINLESS STEEL MUFFLERS.

VEHICLES ARE SUBJECT TO EXCESSIVE UNDERHOOD TEMPERATURES AND FUEL SYSTEM PRESSURES IN SEVERE DUTY APPLICATIONS.

RiskTHIS CREATES POTENTIAL FOR FUEL EXPULSION FROM THE FUELFILLER PIPE WHICH IN THE PRESENCE OF AN IGNITION SOURCE, COULD RESULT IN AFIRE.

FixINSTALL MODIFICATION KITS TO MINIMIZE POSSIBILITY OF FUEL EXPULSION AND TO SHIELD UNDERBODY COMPONENTS FROM EXHAUST SYSTEM HEAT.

EXPULSION OF FUEL DUE TO OVERPRESSURIZATION.

RiskFUEL OR FUEL VAPORS IN THE PRESENCE OF AN IGNITIONSOURCE CAN CAUSE A FIRE.

FixMODIFICATION OF THE BASE FUEL VENTING AND EMISSION CONTROL SYSTEM TO REDUCE OPERATING TEMPERATURES AND FUEL SYSTEM PRESSURES.

WHEN FRONTALLY IMPACTED INTO A FIXED BARRIER AT 30 MPH, AS SPECIFIED IN FEDERAL MOTOR VEHICLE SAFETY STANDARD (FMVSS) NO. 301, THE LEFT FRAME RAILS OF SUCH VEHICLES MAY DISPLACE INBOARD, PINCHING THE FUEL/WATER SEPARATOR CANISTER BETWEEN THE FRAME RAIL AND ENGINE SUFFICIENTLY TO DISPLACE THE FUEL/WATER SEPARATOR DRAIN ROD, ALLOWING THE CONTENTS OF THE CANISTER TO DRAIN. CONSEQUENCE OF DEFECT: FUEL LEAK DURING OR AFTER A CRASH INCREASES THE POSSIBILITY OF A FIRE.

FixINSTALL A CANISTER SHIELD, A REVISED DESIGN DRAIN ROD SHIELD, AND MODIFY FUEL/WATER SEPARATOR MOUNTING BRACKET.

ATTACHING BOLTS ON FUEL TANK SUPPORTS MAY NOT HAVE BEEN ADEQUATELY TIGHTENED; ALSO, THE SUPPORTS ARE TOO THIN. HIGH LEVELS OF STRESS, WHICH COULD OCCUR UNDER NORMAL OPERATING CONDITIONS, COULD CAUSE CRACKS TO DEVELOP IN THE SUPPORT STRAPS. IF THE FUEL TANK SUPPORTS FRACTURE, THE FUEL TANK WILL SLIP FROM THE NORMAL POSITION, AND FUEL LEAKAGE COULD RESULT.

FixFUEL TANK SUPPORTS AND FASTENERS WILL BE REPLACED WITHOUT CHARGE.

SOME OF THE INVOLVED VEHICLES MAY HAVE A DIODE IN THE ELECTRICAL FUEL PUMP CIRCUIT THAT MAY SHORT DURING ENGINE STARTING DUE TO INADEQUATE CAPACITY TO WITHSTAND CURRENT DRAW. A SHORT CIRCUIT WOULD RESULT IN NORMAL ENGINE STARTING, BUT THE PUMP WILL NOT CONTINUE TO SUPPLY THE ENGINE WITH FUEL.

FixTHE DEALER WILL REPLACE DEFECTIVE ELEMENT IN THE ELECTRICAL FUEL PUMP CIRCUIT WITH A NEW RELAY FEED WIRING ASSEMBLY WHICH CONTAINS A LARGER CAPACITY DIODE, FREE OF CHARGE.

ON CERTAIN VEHICLES, THE LOCK WEDGES USED TO SECURE THE AXLE BEARING NUTS TO THE AXLE HOUSING MAY FALL OUT OF POSITION, ALLOWING THE NUT TO LOOSEN. THE NUT ON THE LEFT SIDE MAY FALL OFF, ALLOWING MOVEMENT OF THE AXLE SHAFT.

FixTHE DEALER WILL REPLACE DEFECTIVE LOCK WEDGES WITH AN IMPROVED VERSION. WHEEL BEARINGS WILL BE INSPECTED AND ADJUSTED OR REPLACED, IF NECESSARY.
