What's wrong?
The fuel tubes on the 2020-2023 Spartan K3 diesel engine carry high-pressure fuel from the fuel rail to the injectors for cylinders 4, 5, and 6. The fuel rail holds fuel under pressure, and each injector meters that fuel into its cylinder at the right moment. These tubes have to stay sealed while the engine vibrates and heats up during normal use.
On these K3 chassis, those fuel tubes are vulnerable to metal fatigue. Vibration strain, assembly strain, and material strength combine to stress the tubes until cracks form. Once a tube cracks, pressurized diesel fuel can leak near the engine instead of staying inside the injection system. The replacement tubes add vibration isolators to reduce that strain.
Owners or technicians can detect the leak during maintenance. You can smell fuel or see a fine mist from the leak before the tube failure becomes obvious.
Who's affected?
The scope spans 2020-2023 K3 motorhomes, with the same fuel system component listed for each model year.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific motorhome is included.
What's the safety risk?
A high pressure fuel leak near an ignition source can increase the risk of a fire. A fuel smell, visible mist, or leak found during maintenance is a warning sign. If you notice fuel odor or mist, stop using the vehicle and call a Spartan dealer before another trip. Repair will be free at any franchised Spartan dealer once available.
What should I do?
- Check your VIN to confirm your 2020-2023 Spartan K3 is included in this recall.
- Wait for Spartan owner instructions before scheduling the final fuel-tube repair for this VIN.
- Contact a franchised Spartan dealer to ask whether the free fuel-tube and vibration-isolator repair is open for your chassis.
- Reference recall number 21V969 when you call, and bring the recall notice if you have it.
- Park away from ignition sources and contact Spartan or Cummins Care if you smell diesel fuel or see a fuel leak.
What happens at the repair
At the dealer, a Spartan technician checks whether the engine has 75 miles or less. Engines at or below that mileage get vibration isolators installed on the fuel tubes. Engines above 75 miles get new fuel tubes with vibration isolators. The final dealer repair will be free once available. Spartan has a general reimbursement plan on file, so documented out of pocket repairs can be reviewed through the manufacturer's standard reimbursement process. Keep repair invoices and payment records for the service desk or customer care team.

Recall 21V969 covers 143 2020-2023 Spartan K3 RV chassis vehicles with fuel tubes that can fatigue and crack near the injectors for cylinders 4, 5, and 6. A high pressure fuel leak near an ignition source increases the risk of fire. The dealer repair is free.
What should I do if my 2020-2023 Spartan K3 is on this recall?
Check your VIN to confirm your specific Spartan K3 is included in recall 21V969. If it is, call a franchised Spartan dealer or Cummins Care at 1-800-286-6467 and reference recall 21V969. Ask what repair applies to your engine mileage. The repair is free.

What is the safety risk?
The safety risk is fire from a high pressure diesel fuel leak. The recall concerns fuel tubes that can crack and leak near the engine, where an ignition source turns that leak into a fire risk. If you smell fuel or see a leak, park safely and call the dealer before driving again.
