The problem

Custom Fire Apparatus, Inc. (Custom Fire) is recalling certain 2017-2021 Spartan Gladiator, MetroStar, and MetroStarX emergency vehicles equipped with Cummins L9 diesel engines. The sealing washer may not seat correctly in the pilot boreholes, allowing the high pressure fuel rail assembly to leak.

The risk

A fuel leak in the presence of an ignition source increases the risk of a fire.

The fix

Cummins will inspect the rail threads and fuel lines, and replace the rail as necessary, free of charge. Owner notification letters were mailed on August 8, 2021. Owners may contact Custom Fire's customer service at 1-715-294-2555.
