## The problem

Tiffin Motorhomes, Inc. (Tiffin) is recalling certain 2017-2021 Bus and Phaeton vehicles.  The sealing washer may not seat correctly in the pilot bore, allowing the high pressure fuel rail assembly to leak.

## The safety risk

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

## The remedy

Tiffin will work with Cummins to inspect the rail threads , and replace the rail and fuel lines if damage is found, free of charge.  Owner notification letters were mailed August 11, 2021.  Owners may contact Tiffin customer service at 1-256-356-8661.
