What's wrong?
The CK7G generator in 2021-2023 Atc Commercial Office trailers supplies electrical power for office equipment and trailer systems when shore power is not connected. It uses a fuel line assembly to carry fuel to the generator in a controlled path. That line needs to be tight and routed away from places where heat or movement can damage it.
In NHTSA campaign 24V638, the problem is a fuel line assembly on the generator that is loose or routed incorrectly. Fuel can leak from that assembly. ATC traced the issue to CK7G generators identified by CK Power and found that 12 of those generators had been installed in Commercial Office trailers. The remedy installs parts kits and reroutes the hoses to remove the fire risk.
There is no warning sign before failure. The filing does not describe a light, sound, smell, or other cue an owner should expect before a leak begins.
