Issue: On certain motorhomes, the fuel tubes between the fuel rail and the injectors may crack and create a fuel leak. Note: This recall only affects motorhomes equipped with a Cummins X12 diesel engine. Safety Risk: A fuel leak can create the risk of a fire. Corrective Actions: Cummins will notify owners by mail and instruct you to take your motorhome to a Cummins authorized service center. On vehicles with 120 km or less, Cummins will add vibration isolators to the fuel tubes. On vehicles with more than 120 km, Cummins will also replace the fuel tubes for cylinders 4, 5 and 6.
