What's wrong?
The auxiliary fuel pickup tube on certain 2013-2014 Thomas Built Buses Saf-T-Liner Ef, Saf-T-Liner Hdx, and Saf-T-Liner Efx buses feeds diesel fuel from the tank to the optional chassis coolant heater. That heater uses fuel to warm the chassis coolant before or during operation, so the pickup tube has to stay clear inside the tank.
The problem is the information label attached to the auxiliary heater fuel pickup tube. On affected buses, that label can detach from the tube and fall into the fuel tank. Once loose in the tank, the label can interfere with fuel delivery to the engine. If fuel flow is blocked, the engine does not get the steady supply it needs to keep running.
A driver or fleet operator does not get a reliable early symptom from this defect. There is no warning sign before failure.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
Insufficient fuel delivery can make the engine stumble, run erratically, or stall while driving, which increases crash risk. If the engine starts to stumble or run erratically, move out of traffic when safe and contact a franchised dealer. Repair will be free at any franchised Thomas Built Buses dealer once available.
What should I do?
- Check your VIN to confirm your 2013-2014 Thomas Built Buses Saf-T-Liner Ef, Saf-T-Liner Hdx, or Saf-T-Liner Efx bus is included in this recall.
- Contact a franchised Thomas Built Buses dealer and ask whether recall number 13V364 is open for your VIN.
- Schedule the free fuel-tank and auxiliary-heater pickup-tube label inspection that fixes the label issue linked to fuel delivery trouble and engine stalling.
- Bring the recall notice if Thomas Built Buses mailed one. If not, reference recall number 13V364 when you call.
- Drive cautiously until the inspection is complete. Pull over safely if the engine stumbles, runs erratically, or stalls.
What happens at the repair
At the dealer, a Thomas Built Buses technician inspects the fuel tanks and auxiliary heater fuel pickup tubes for information labels. If a label is found, the technician removes it so it cannot detach inside the fuel tank and restrict fuel delivery to the engine. The dealer repair will be free once available, with parts and labor covered under the recall.
