1983 Ford E-350 Econoline Recall

HEATER HOSE MAY BE INCORRECTLY ROUTED.

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

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

EXPULSION OF FUEL DUE TO OVERPRESSURIZATION.

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.

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.

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.

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.
