Engine News SEBD9335-00, July 2004, "Internal Components for Remanufactured Injectors are Now Coated for Increased Service Life". Replace the article with the following information.

The fuel injection pump plungers of remanufactured injectors are now tungsten carbide coated. This coating will help to prevent the plunger from seizing in the body. The coating will also increase the service life of the injector.

This change is due to the increased distribution of low sulfur fuels.

Use the cross reference to obtain the new part numbers when you order remanufactured injectors:
