There can be variations in the parts within a Critical Parts List group, you really need the engine serial number. Cummins, or any Cummins reseller  (like we are at our shop) can go into Cummins Quick Serv and use the ESN to get a comprehensive parts list for that engine as it left Cummins as well as the original build date. John call me at home, or e-mail me when you get your CPL/ESN I can run them on lunch. E-mail at work is ian(at)dieselcranks(dot)com, home is iscam (at) sbcglobal (dot) net.
