Oshkosh is recalling 1,608 2019-2022 S-Series vehicles because fuel tubes between the fuel rail and injectors for cylinders 4, 5, and 6 can crack and leak high pressure fuel. A leak near an ignition source can increase the risk of a fire, and the Oshkosh dealer repair will be free once Oshkosh makes it available.

What's wrong?
The injector fuel supply tube on 2019-2022 Oshkosh S-Series vehicles carries diesel fuel from the fuel rail to the injector. The fuel rail holds fuel under high pressure, and the injector meters that fuel into the engine cylinder at the right moment. These tubes feed cylinders 4, 5 and 6.
On affected vehicles, those tubes are susceptible to cracking. Cummins traced the problem to metal fatigue from vibration, assembly strain and material strength. As the tube flexes and vibrates during engine operation, a crack forms and opens a path for a high pressure fuel leak. The replacement tube setup adds vibration isolators to reduce that strain.
An owner or operator can detect the problem during maintenance. You can smell fuel or see a mist near the engine area if the tube has started leaking.
Who's affected?
Spans 4 model years of the S-Series, all tied to the same injector fuel supply tube in the fuel system.

A matching 2019-2022 Oshkosh S-Series truck does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
A high pressure fuel leak near an ignition source can increase the risk of a fire. Fuel smell or visible fuel mist is a warning sign. If you notice either one, stop operation and call the dealer before using the vehicle again. Repair will be free at any franchised Oshkosh dealer once available.
What should I do?
- Check your VIN to confirm your 2019-2022 Oshkosh S-Series is included in this recall.
- Contact Oshkosh customer service at 920-235-9151 to confirm the current repair status before scheduling service.
- Reference recall number 22V008 when you call Oshkosh or a franchised Oshkosh dealer.
- Ask whether your S-Series needs vibration isolators or replacement fuel tubes to stop cracking that can cause a high pressure fuel leak.
- Avoid operating near ignition sources and arrange service promptly once Oshkosh confirms the free repair is open.
What happens at the repair
Because the remedy is still under development, do not assume the final dealer repair is open for scheduling. Once available, an Oshkosh technician will handle the fuel tube repair by mileage: engines with 75 miles or less get vibration isolators installed on the fuel tubes, while engines above 75 miles get new fuel tubes with vibration isolators. Parts and labor will be free under the recall. Oshkosh's standard reimbursement plan covers eligible documented expenses, so keep paperwork for any related fuel tube repair you already paid for and ask Oshkosh customer service how to submit it.

Frequently asked questions
What is recall 22V008?
Recall 22V008 covers 1,608 2019-2022 Oshkosh S-Series vehicles with fuel tubes that can crack between the fuel rail and injectors for cylinders 4, 5, and 6. A high pressure fuel leak near an ignition source increases fire risk.
What should I do if my 2019-2022 Oshkosh S-Series is on this recall?
Check your VIN to confirm your specific vehicle is included in recall 22V008. If it is, contact a franchised Oshkosh dealer or Oshkosh customer service to confirm current repair availability. The dealer repair is free once Oshkosh opens the remedy.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost. Oshkosh says dealers will install vibration isolators on engines with 75 miles or less, or install new fuel tubes with vibration isolators on engines with more than 75 miles.
What is the safety risk?
The safety risk is fire. The recalled fuel tubes can crack and cause a high pressure fuel leak. If that leaked fuel reaches an ignition source, the condition increases the risk of a fire.
When were owners notified about recall 22V008?
Oshkosh listed February 1, 2022, for owner notification letters. If you bought the vehicle used or never received a letter, the VIN still decides whether recall 22V008 applies. Reference recall number 22V008 when you contact the dealer.
