00V124000Fuel SystemMay 1, 2000 · 719 units

Defect

VEHICLE DESCRIPTION: MEDIUM DUTY TRUCKS. THE DIESEL ENGINE FUEL SUPPLY HOSE FROM THE FUEL FILTER TO THE TOP OF THE FUEL INJECTION PUMP IS INCORRECTLY ROUTED.

Consequence

THIS CONDITION COULD ALLOW THE HOSE TO COME IN CONTACT WITH THE ENGINE BLOCK, CAUSING THE HOSE TO WEAR OUT.

Remedy

DEALERS WILL REPLACE THE EXISTING DIESEL FUEL HOSE WITH A REDESIGNED FUEL HOSE THAT HAS A DIFFERENT SHAPE FROM THE EXISTING FUEL HOSE. DUE TO THE DESIGN CHANGE AND ROUTING CHANGE OF THE REDESIGNED FUEL HOSE, THE ENGINE ELECTRICAL HARNESS CONNECTOR BRACKET AND THE FICD VALVE BRACKET WILL REQUIRE REPLACEMENT WITH REDESIGNED BRACKETS. THIS WILL PROVIDE ADDITIONAL CLEARANCE BETWEEN THESE BRACKETS AND THE REDESIGNED FUEL HOSE.

Defect

VEHICLE DESCRIPTION: MEDIUM DUTY TRUCKS. THE FUEL FILTER SUPPORT BRACKET CAN CRACK AND BREAK DUE TO VIBRATION, WHICH COULD ALLOW THE FUEL FILTER TO SEPARATE AND LODGE ON TOP OF THE CHASSIS FRAME.

Consequence

THE FUEL FILTER SUPPORT BRACKET COULD THEN COME IN CONTACT WITH THE ENGINE ASSEMBLY.

Remedy

DEALERS WILL REPLACE THE FUEL FILTER BRACKET WITH A REDESIGNED FUEL BRACKET TO PREVENT CRACKING AND BREAKING DURING NORMAL VEHICLE OPERATION.
