Mitsubishi Fuso is recalling 4,885 2012-2013 FEC72, FEC52, FEC92, and FGB72 trucks because an incorrectly routed low-pressure fuel return hose can slip off the filter and leak fuel. Fuel near an ignition source raises the risk of a fire; the dealer repair will be free once Mitsubishi Fuso makes it available.

What's wrong?
The low pressure fuel return hose on the 2012-2013 Mitsubishi Fuso FEC72, FEC52, FEC92, and FGB72 trucks carries unused fuel back through the fuel system after the engine has taken what it needs. Near the fuel filter, the hose is held in place by a clamp so the line stays seated on the filter connection while the truck runs and vibrates.
On these trucks, the return hose and filter were routed incorrectly at the clamp near the filter. That routing leaves the hose less secure than designed, so the hose can slip off the filter connection. Once it separates, fuel leaks from the return line instead of staying inside the system.
There is no warning sign before failure. If the hose has already moved or separated, an owner or technician can see leaking fuel around the filter area during inspection.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific truck.
What's the safety risk?
Fuel leaking near an ignition source raises the risk of a fire. If your VIN is included, schedule the recall repair soon and treat fuel odor or a visible leak as a reason to stop and call a dealer before the next trip. Repair will be free at any franchised Mitsubishi Fuso dealer once available.
What should I do?
- Check your VIN to confirm your 2012-2013 Mitsubishi Fuso FEC72, FEC52, FEC92, or FGB72 truck is included in this recall.
- Contact a franchised Mitsubishi Fuso dealer and ask whether the free fuel-return-hose routing repair is open for your VIN.
- Schedule the hose-and-filter routing correction and added clip, which helps keep the fuel return hose from slipping off and leaking fuel.
- Bring the recall notice if you have it. If not, reference recall number 12V424 when you call.
- Avoid driving if you smell fuel or see a fuel leak. Park away from ignition sources and call Mitsubishi Fuso customer service at 1-856-467-4500 for guidance.
What happens at the repair
At the dealer, a Mitsubishi Fuso technician checks the low pressure fuel return hose and filter routing at the hose clamp near the filter. The repair corrects the hose and filter routing and adds a clip to the fuel return hose so the hose stays secured to the filter. The dealer repair will be free once available for your VIN. Parts and labor are covered under the recall.
