The defect
On certain motor homes built on workhorse chassis and equipped with gm 8.1L V8 engines, improper hardening during the heat treatment process can cause the fuel rail pulse damper retainer clip to fracture, resulting in inadequate retention of the damper. if the damper becomes loose, fuel could be pumped by the fuel pump into the under hood area.
The risk
In the presence of an ignition source, a fire could result.
