- 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.

Fuel System recalls for the 2003 Mack CX
- The problem
- On certain trucks, a leak in the aset ac fuel injection line may spray fuel on the exhaust gas recirculation pipes that carry hot exhaust gases .
- The risk
- THIS COULD POTENTIALLY RESULT IN AN ENGINE FIRE.
- The fix
- Mack has issued a stop work on this campaign under further notice (2-22-2007). The remedy does not adequately address the issue on all vehicles. Mack will re-release the recall in the near future. (Please see nhtsa no. 07V159/mack recall no. Sco323 for vehicles that have had this repair already performed.) This recall has been superseded (please see 07v401/sc0324).
- The problem
- On certain heavy duty class 8 diesel trucks equipped with aset ac engines, the location of the fuel inlet hose may result in overheating or abrasion of the hose, which may lead to a premature failure.
- The risk
- 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. Due to some quality and supply issues with parts to support this safety recall, owners may have been informed during april 2005,that the safety recall was on hold. These issues have now been resolved. For owners who have not had their vehicle(s) repaired, contact a mack parts and service center immediately to schedule an appointment to have your vehicle(s) repaired. Owners may contact mack trucks at 610-709-2131.
