What's wrong?
The high pressure fuel rail on the diesel engine in these Spartan K2 and K3 motor home chassis is the metal pipe that holds pressurized diesel fuel and feeds it to the injectors. Sealing washers sit in pilot bores at each end of the rail to keep that fuel sealed inside the system. When the washer seats correctly, the joint stays tight under the high pressures the rail sees in normal operation.
On affected chassis, the pilot bores in the fuel rail were machined undersized, so the sealing washer does not seat the way it should. Without a proper seat, the joint never gets the clamping load it needs, and over time the seal loosens and lets pressurized diesel fuel leak out of the rail.
The operator will often see or smell diesel fuel around the engine. In some cases, the check engine light comes on. Either one is a warning sign that the rail joint has started to leak.

What's the safety risk?
A fuel leak near an ignition source raises the risk of a fire. Watch for the smell of diesel, visible fuel under the chassis, or a check engine light, and stop driving if any of those appear. Park away from buildings until the vehicle has been inspected, and call the dealer to schedule service. Repair is free at any franchised Spartan dealer.
What should I do?
- Check your VIN to confirm your 2017-2022 Spartan K2 or K3 RV chassis is included in this recall.
- Contact a franchised Spartan dealer to schedule the free fuel-rail inspection that addresses the leak-prone sealing washer.
- Reference recall number 21V319 (Spartan recall 21-11) when you call the dealer so the service desk pulls the correct repair.

- Keep the chassis away from open flames, sparks, and other ignition sources until the fuel-rail repair is complete.
What happens at the repair
At the dealer, a Spartan technician inspects the high pressure fuel rail threads and the fuel lines, then replaces the rail if the inspection shows it is needed. Parts and labor are free under the recall. If you previously paid out of pocket for this repair, Cummins is handling reimbursement through its Recall Portal for units not covered by the manufacturer's limited warranty. Bring your repair receipts and documentation to the service desk so the dealer can route the claim correctly.
