PROBLEM
Show/hide table
| The low pressure fuel line needs to be replaced on certain 924H, 924H Z, 928H, and 930H wheel loaders. The existing low pressure fuel line has a defective internal bore surface. Debris from this surface can damage the injector valve seats, causing high injector leak off and in some instances failure to start. |
