The defect
Gillig, LLC (Gillig) is recalling certain 2023 Low Floor buses equipped with Cummins L9 diesel engines with part number D563027BX03. Insufficient crimping may allow the remote fuel filter hoses to disconnect and leak, decreasing fuel supply to the engine.
The risk
A fuel leak in the presence of an ignition source increases the risk of a fire. Additionally, a lack of fuel can cause an engine stall, increasing the risk of a crash.
