What's wrong?
The propane fuel system on 2011-2013 Micro Bird G5 School Bus school buses supplies propane from the fuel storage system to the engine. In this recall, the affected area is where an aluminum fuel line fitting meets the brass supply valve housing. That joint has to stay sealed while fuel moves through the system.
On affected buses, the aluminum and brass parts react where they touch. That metal-to-metal reaction damages the sealing area at the fitting and valve housing. Once the joint no longer seals correctly, propane can leak from that connection instead of staying inside the fuel line.
There is no warning sign before failure. A propane odor around the bus or fuel system is not listed as an advance warning in the recall, so the absence of a smell or visible leak does not confirm the bus is safe.
Who's affected?
Covers three model years of the same school bus platform, all tied to the fuel system.

What should I do?
- Check your VIN to confirm your 2011-2013 Micro Bird G5 School Bus is included in this recall.
- Contact a franchised Micro Bird dealer to schedule the free stainless-steel fuel-line-fitting replacement that fixes the propane leak risk at the supply valve connection.
- Bring the recall notice if you have it. Reference recall number 14V337 and Micro Bird recall 14-057-RSU when you call.
- Keep the bus away from ignition sources and stop using it if you smell propane or see signs of a fuel leak.
What happens at the repair
At the dealer, a Micro Bird technician replaces the aluminum fuel line fitting with a new stainless steel fitting where the fuel line meets the brass supply valve housing. That swap removes the mixed metal contact described in recall 14V337. The recall repair is free, and parts and labor are covered. After the fitting is replaced, ask the service desk to document the completed recall on the repair order before the bus returns to service.
