The problem
ON CERTAIN TRANSIT BUSES BUILT WITH CUMMINS ISL AND ISC DIESEL ENGINES EQUIPPED WITH THE CM850 FUEL SYSTEM, THE ENGINE HIGH PRESSURE FUEL LINES, FROM THE ENGINE HIGH PRESSURE PUMP TO THE ENGINE FUEL RAIL, ARE PRONE TO FAILURE.
Risk
FAILURE OF THE LINE INTRODUCES HIGH PRESSURE FUEL SPRAY INTO THE ENGINE COMPARTMENT WHICH CAN IGNITE WHEN IT COMES IN CONTACT WITH A HOT SURFACE.
What owners should do
CUMMINS WILL INSTALL A FUEL LINE BRACKET TO REDUCE FUEL LINE STRESS. A NEW FUEL LINE WILL BE INSTALLED WHEN ADDING THE BRACKET (PLEASE SEE 06E037). GILLIG NOTIFIED CUSTOMERS ON NOVEMBER 22, 2006. CUSTOMERS MAY CONTACT CUMMINS AT 1-800-343-7357 OR GILLIG AT 510-264-5031.
