FUEL SYSTEM, GASOLINE:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS
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.
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.
