Recall 12V311 affects 313 2010-2012 Pierce vehicles for fuel-line support damage. Repair is free at a franchised Pierce dealer.
Pierce is recalling 313 2010-2012 Arrow Xt, Velocity, Dash Cf, Contender Big Block, and Quantum vehicles with Detroit Diesel DD13 engines because fuel line supports can loosen after service work, crack the high-pressure fuel line, and cause a fuel leak.

What's wrong?
The high pressure fuel line on affected 2010-2012 Pierce Arrow Xt, Velocity, Dash Cf, Contender Big Block, and Quantum vehicles carries diesel fuel from the pump to the fuel rail on Detroit Diesel DD13 engines. The fuel rail feeds the injectors, so the line has to stay secure while the engine runs under pressure and vibration.
The problem is in the support system for the pump-to-rail fuel line. That support system is sensitive to assembly torque, which means service work on nearby parts can damage or loosen the supports if they are tightened incorrectly. Once the supports loosen, the fuel line is left with extra movement. Over time, that movement can crack the line and allow diesel fuel to leak.
There is no warning sign before failure. The recall information does not name an earlier symptom an owner or operator can rely on before the fuel line cracks.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
A fuel leak near an ignition source can start a fire. If your VIN is included, schedule the recall repair soon and treat any sign of leaking fuel as a reason to stop using the vehicle and call the dealer. Repair will be free at any franchised Pierce dealer once available.
What should I do?
- Check your VIN to confirm your 2010-2012 Pierce Arrow Xt, Velocity, Dash Cf, Contender Big Block, or Quantum is included in this recall.
- Contact a franchised Pierce dealer or DTNA authorized service facility to ask whether the free high-pressure fuel-line support replacement is open for recall number 12V311.
- Bring the Pierce owner notice from July 18, 2012 if you have it. If not, give the service desk recall number 12V311 when you call.
- Ask the service desk to inspect the diesel fuel-line support system that loosens after service work and allows the high-pressure fuel line to crack and leak.
- Keep the vehicle away from ignition sources if you smell diesel fuel or see a leak, and do not operate it until service guidance is clear.
What happens at the repair
The source remedy says Pierce will notify owners and the high pressure fuel line support system will be replaced at an authorized service facility, free of charge. Because the remedy status is not listed, confirm scheduling before you bring the vehicle in. At the service facility, a Pierce technician replaces the support system for the pump to rail high pressure fuel line, the part that helps keep the fuel line secured after service work. The repair will be free once available.
