- The problem
- On certain trucks equipped with aset ac model engines, the engine as configured with an external exhaust gas recirculation system makes servicing the fuel injection lines difficult when using traditional tools. Therefore, it is possible for fuel leaks to develop when removing and installing the fuel injection lines.
- The risk
- A leak in the fuel injection line may spray fuel on the hot surfaces of the exhaust gas recirculation system, which could result in an engine fire.
- The fix
- Dealers will replace the fuel injection lines free of charge. Note: this recall supersedes a previous campaign conducted in 2006 (please see 06v392). The recall began on september 11, 2007, with subsequent mailings every six weeks until april 2008. Owners may contact mack at 800-528-6586.

- If the hose fails, fuel can be sprayed on the exhaust manifold, which could potentially lead to an engine compartment fire.
- The fix
- Dealers will repair and replace the fuel inlet hose free of charge. The recall began on february 14, 2005.
