Fccc is recalling 476 2021-2022 Xc Chassis and Xb Chassis vehicles equipped with Cummins L9 diesel engines, remote Stage 2 fuel filters, and pressurized hoses because the fuel hose between the fuel pump and remote filter head can leak. A fuel leak near an ignition source increases the risk of fire, and the Fccc dealer repair will be free once available.

What's wrong?
The fuel hose on the 2021-2022 Fccc Xc Chassis and Xb Chassis carries diesel fuel under pressure between the fuel pump and the remote Stage 2 fuel filter head. That filter head is mounted away from the engine, so the hose and its quick-connect fittings have to hold fuel securely while the engine is running.
On affected chassis with Cummins L9 diesel engines, a leak can develop in the hose between the pump and the remote filter head. The issue is tied to the remote filter setup with pressurized fuel hoses. Once the hose no longer keeps fuel contained, diesel fuel can escape from the fuel system instead of moving cleanly through the filter path.
There is no warning sign before failure. An owner should not count on a dashboard message or drivability change to appear before the leak starts.
Who's affected?
Covers Xc Chassis and Xb Chassis from the 2021 and 2022 model years; both use the same fuel hose assembly.

A matching year and chassis model does not confirm inclusion. Check your VIN to confirm whether this recall applies to your specific vehicle.
What's the safety risk?
A fuel leak near an ignition source increases the risk of a fire. If your VIN is included, schedule the recall repair as soon as Fccc makes it available. Treat visible fuel or fuel smell as a reason to stop and call the dealer before more driving. Repair will be free at any franchised Fccc dealer once available.
What should I do?
- Check your VIN to confirm your 2021-2022 Fccc Xc Chassis or Xb Chassis is included in this recall.
- Confirm the free fuel-hose replacement is open for your VIN before scheduling service.
- Contact a franchised Fccc dealer for the Cummins fuel-hose replacement that fixes the pressurized fuel leak risk.
- Bring the owner letter if you have it. If not, reference recall number 21V556 when you call.
- Avoid driving if you smell fuel or see a fuel leak. Park away from ignition sources and contact Fccc customer service at 1-800-547-0712.
What happens at the repair
The final repair is still listed as under development, so do not assume an appointment can be completed until the repair opens. Once available, an Fccc technician at an authorized service facility will replace the fuel hoses connected to the Cummins L9 diesel engine fuel system. Parts and labor are covered under the recall. The filing identifies fuel hose replacement as the repair path, but it does not give a completed reimbursement program.

Frequently asked questions
What is recall 21V556?
Recall 21V556 covers 476 2021-2022 Fccc Xc Chassis and Xb Chassis vehicles with Cummins L9 diesel engines, remote Stage 2 fuel filters, and pressurized hoses. The fuel hose between the fuel pump and remote fuel filter head can leak, increasing fire risk near an ignition source.
What should I do if my 2021-2022 Fccc Xc Chassis or Xb Chassis is on this recall?
Check your VIN to confirm your specific chassis is included in recall 21V556. If it is, contact a franchised Fccc dealer or DTNA customer service at 1-800-547-0712 and ask about the Cummins fuel-hose replacement path. Reference DTNA recall FL-897 when you call.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost, and the remedy states that Cummins will replace the fuel hoses free of charge. Parts and labor are covered for included vehicles.
Is it safe to drive before the fuel hose recall is fixed?
The official risk is a fuel leak that increases fire risk when an ignition source is present. This recall is not marked do-not-drive, but fuel smell, visible fuel, or wetness near the fuel system needs dealer guidance before further driving.
When were owners notified about recall 21V556?
Owner notification letters were mailed on September 3, 2021. If you bought the chassis used or never received a letter, the VIN still decides whether the recall applies. Check your VIN, then reference recall 21V556 or DTNA number FL-897 with the dealer.
