Since February 2, 2010, Alliant Power has been laser etching the injector part number on the nozzle nut of G2.8 Injectors for easy and proper identification. As of September 23, 2014, the laser etched part number on the nozzle nut will be the only unique identifier to distinguish between G2.8 Injector part numbers. The wire guide and wire tie will no longer be unique to a specific G2.8 Injector part number. The images below show the array of wire guide colors that may be found on Alliant Power G2.8 Injectors. Alliant Power Technical Bulletin APTB 03/06 R1 has also been updated to
reflect these changes.
