The defect
Gillig LLC (Gillig) is recalling certain model year 2014 Low Floor transit buses manufactured from May 23, 2014, through August 1, 2014. The Cummins ISB or ISL engines in these vehicles may have been equipped with Fleetguard UFF-XT fuel filters, part number FF63009, whose filter shell may separate from the fuel filter nut plate causing the engine to stall without warning.
The risk
If the engine stalls unexpectedly there is an increased risk of a crash.
