The defect
ON CERTAIN TRUCKS EQUIPPED WITH ASET AC MODEL ENGINES, THE ENGINE AS CONFIGURED WITH AN EXTERNAL EXHAUST GAS RECIRCULATION SYSTEM MAKES SERVICING THE FUEL INJECTION LINES DIFFICULT WHEN USING TRADITIONAL TOOLS. THEREFORE, IT IS POSSIBLE FOR FUEL LEAKS TO DEVELOP WHEN REMOVING AND INSTALLING THE FUEL INJECTION LINES.
The risk
A LEAK IN THE FUEL INJECTION LINE MAY SPRAY FUEL ON THE HOT SURFACES OF THE EXHAUST GAS RECIRCULATION SYSTEM, WHICH COULD RESULT IN AN ENGINE FIRE.
