The defect
Oshkosh Corporation (Oshkosh) is recalling certain 2019-2022 S-Series vehicles. The fuel tubes between the fuel rail and the injector for cylinders 4, 5 and 6 may be susceptible to cracking, resulting in a high pressure fuel leak.
The risk
A high pressure fuel leak in the presence of an ignition source may increase the risk of a fire.
The remedy
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 are expected to be mailed February 1, 2022. Owners may contact Oshkosh customer service at 1-8088-686-7278.
