Cummins is recalling 4,413 ISL remanufactured diesel engines sold as replacement equipment.
The sealing washer may not seat correctly in the pilot bore holes, allowing the high pressure fuel rail assembly to leak.
A fuel leak in the presence of an ignition source increases the risk of a fire.
What to do
Dealers will inspect the rail threads and fuel lines for damage, and replace the rail -- as necessary -- free of charge.
Owner notification letters are expected to be mailed August 20, 2021.
Owners may contact Cummins customer service at (800) 286-6467. Cummins' number for this recall is C2449.
