What's wrong?
The fuel pump on 2025 International Hx and Lt trucks with Cummins X15 diesel engines moves fuel through the engine at the pressure needed for normal combustion. Inside that pump, the fuel pump barrels help meter and pressurize diesel before it reaches the engine. The truck depends on those parts staying strong under repeated pressure cycles.
On included trucks, some fuel pump barrels were built with a surface that was not hardened correctly during heat treatment. A later finishing step, called shot peening, is supposed to strengthen the part by compressing its surface, but the softer abnormal layer kept that step from working as designed. With lower fatigue strength, a barrel can fracture, leak diesel fuel, and starve the engine of fuel pressure. That loss of pressure can reduce engine performance or stall the engine.
Before failure, the operator can notice reduced performance or a warning lamp when fuel pressure drops. People in or around the truck can also see or smell diesel fuel.
Who's affected?
Covers the Hx and Lt truck lines with the same heavy duty diesel engine fuel-pump setup.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
An engine stall increases the risk of a crash. Reduced performance, a warning lamp, visible diesel fuel, or the smell of diesel fuel point to fuel pressure trouble. If any of those signs appear, pull over safely and contact the dealer before continuing. Repair is free at any franchised International dealer.
What should I do?
- Check your VIN to confirm your 2025 International Hx or Lt is included in this recall.
- Contact a franchised International dealer to schedule the free fuel-pump-barrel replacement that fixes the fracture risk behind the fuel leak and engine stall.
- Bring the owner letter if you have it. If not, reference recall number 24V734 when you call.
- Drive cautiously until the repair is complete, and move out of traffic if the engine stalls.
What happens at the repair
At the dealer, an International technician works with Cummins to replace the fuel pump barrels in the Cummins X15 diesel engine. The recall repair is free, with parts and labor covered. International has a general reimbursement plan on file for this campaign. If you already paid for a related fuel pump barrel repair before the recall notice, ask International Customer Service or Cummins Customer Service how to submit documentation under that plan.
