Recall 86V016000
Fuel System, Gasoline › Delivery — Western Star · reported 4 Feb 1986 · 5 vehicles potentially affected
What's wrong
THE ENGINE CONTINUES TO RUN OR CAN START UP WHEN THE SENTINEL SHUTDOWN UNIT BLOCKS THE FLOW OF FUEL. THIS ALLOWS FUEL PRESSURE TO BUILD UP IN THE FUEL LINE WHICH MAY CAUSE THE FUEL LINE OR FILTER TO SPLIT OPEN AND LEAK OR SPRAY FUEL INTO THE ENGINE COMPARTMENT. CONSEQUENCE OF DEFECT: IF THIS OCCURS, THE FUEL LEAKING OR SPRAYING INTO THE ENGINE COMPARTMENT MAY CAUSE A FIRE. NOTE: AN IMMEDIATE STEP TO BE TAKEN TO PREVENT A FAILURE IS TO TURN THE CONTROL HANDLE ON THE SENTINEL SHUTDOWN UNIT FROM "RUN" TO "BYPASS".
The fix
INSTALL A PRESSURE RELIEF VALVE INTO THE FUEL SUPPLY LINE.
SYSTEM: FUEL LINES. VEHICLE DESCRIPTION: HEAVY DUTY CONVENTIONAL TRUCKS 33,000 LBS. AND GREATER GVWR EQUIPPED WITH CATERPILLAR 3406B DIESEL ENGINES.
