Cummins, Inc. (Cummins) is recalling certain X12 Diesel Engines, with part numbers D0S3005BX03 and D0S3009BX03. The fuel tubes between the fuel rail and the injectors for cylinders four, five, and six may fatigue and crack, which can result in a high pressure fuel leak.

On engines with 75 miles or less, dealers will install vibration isolators to the fuel tubes. Engines with more than 75 miles will receive new fuel tubes with vibration isolators. Repairs will be performed free of charge. Owner notification letters were mailed March 11, 2022. Owners may contact Cummins customer service at 1-800-286-6467.
