What's wrong?
The fuel return line on affected 2017-2023 Blue Bird Vision School Bus and Vision buses is part of the LPG fuel system. It carries unused fuel back from the fuel rail pressure control module area to the tank return valve, so the system can manage fuel flow without leaking at the fittings.
On these buses, the return line assembly uses a zinc-plated carbon steel fitting next to a stainless-steel crimp collar. Road debris can chip away the zinc plating, and road salt and moisture can let the two different metals corrode where they touch. Over time, corrosion can weaken the fitting enough for the fuel return line to leak.
What you can see before a leak is significant red rust on the fuel return line connector fitting. If that rust is present, treat it as the warning sign and have the bus checked under NHTSA campaign 22V579.

What's the safety risk?
A corroded fuel return line can leak fuel, which increases the risk of a fire. Red rust on the fuel return line connector fitting is a warning sign before a leak, so schedule service promptly if you see rust or notice fuel leaking. Repair will be free at any franchised Blue Bird dealer once available.
What should I do?
- Check your VIN to confirm your 2017-2023 Blue Bird Vision School Bus or Vision is included in this recall.
- Use the Blue Bird owner letter mailed May 24, 2023, as your notice, or ask Blue Bird customer service for a copy if you bought the bus used.
- Call Blue Bird customer service at 1-478-822-2242 to ask when the free fuel-return-line replacement is open, and reference recall number 22V579.
- Avoid route use if you smell fuel or see a fuel leak; have the bus inspected before putting it back in service.
- Schedule the fuel-return-line replacement once Blue Bird opens the repair so the corroding LPG fuel line is replaced free of charge.
What happens at the repair
Once the final repair is available, a Blue Bird technician will replace the fuel return lines covered by recall 22V579. The repair is free, and Roush's reimbursement language says the labor cost for the recall repair is covered at no cost to the dealer or the vehicle owner. If a related repair invoice exists, ask the Blue Bird service desk or Blue Bird customer service how Roush's labor reimbursement applies before paying again. Until the repair opens, confirm the vehicle's recall status and follow any interim guidance from Blue Bird.
