Kme is recalling 386 2012-2021 Custom Chassis vehicles because a sealing washer can sit incorrectly in the pilot bore holes and allow the high pressure fuel rail assembly to leak. A fuel leak near an ignition source increases the risk of a fire, and Kme dealers will complete the recall repair free of charge.

What's wrong?

The high-pressure fuel rail on 2012-2021 Kme Custom Chassis vehicles stores pressurized diesel fuel and sends it to the injectors. A sealing washer at the rail end helps close the joint so fuel stays inside the rail while the engine is running. The pilot bore is the machined pocket that positions that washer.

On affected chassis, the pilot bore in the fuel rail end can be too small. That prevents the sealing washer from sitting flat and fully loaded against the rail. With engine vibration, heat, and fuel pressure, the joint loses its seal and diesel fuel can leak from the high-pressure rail assembly.

An operator can see or smell diesel fuel before the problem becomes worse. In some cases, the check engine lamp can also turn on. Those are the warning signs to describe when contacting a Kme dealer or service facility.
