Cummins Inc. has decided that a defect which relates to motor vehicle safety exists in certain Cummins X12 Engines that were manufactured between April 26, 2016 and November 1, 2021 and for installation in mixer, truck, coach, emergency vehicle, refuse truck, recreational vehicle and crane applications. This notice applies to the engines(s)/vehicles(s) listed on the enclosed table. You previously received a letter informing you of this recall and advising you that Cummins was developing a remedy. A remedy is now available for your engine/vehicle. WHAT IS THE PROBLEM? The fuel tubes between the fuel rail and the injectors for cylinders 4, 5 and 6 may be susceptible to cracking, resulting in a high pressure fuel leak. A high pressure fuel leak in the presence of an ignition source may increase the risk of a fire. WHAT ARE WE DOING ABOUT THE PROBLEM? Cummins has released field Safety Campaign #C2532, X12 CM2350 X119B and X12 CM2450 X137B Fuel Injector Supply Line Safety Campaign to correct this condition by replacing the fuel tubes with new fuel tubes and installing vibration isolators for cylinders 4,5 and 6. This campaign is currently available at Cummins Distributors and authorized Warranty dealers. The repair will be completed free of charge and most applications will require approximately 2 hours to complete. WHAT SHOULD YOU DO? Contact the nearest Cummins Distributor or authorized Warranty Dealer to arrange to have this campaign performed on your engine. The distributor or dealer will work with you to schedule the best date to complete the repair. In the meantime, Cummins advises you to periodically check the injector fuel tubes for signs of leaking and to seek repairs if leaks are identified. If a leak occurs, the operator may smell diesel fuel or observe a mist. C Cummins Inc.
