2023 THOR MOTOR COACH TELLARO

FUEL SYSTEM, GASOLINE:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS

Thor Motor Coach (TMC) is recalling certain 2021-2023 Sequence, 2021-2024 Rize, Scope, Tellaro, 2023-2024 Dazzle, and Twist motorhomes, equipped with certain Cummins Onan QG 2800i generator sets. The fuel hose between the inline fuel filter and the injection pump module (IPM) may have inadequate clamp force, possibly resulting in a gasoline leak.

Risk: A gas leak in the presence of an ignition source increases the risk of a fire.
