Suggest you join the Cummins Quickserve site

Once you register you input your engine SN. This will provide all information specific to your engine.
From there you have access to lots of information including parts which is provided in a diagram form with a breakdown of all parts for that component. If the part number has changed it will provide that information.
There is also an extensive library of service informaiton. I downloaded a complete service manual for my engine (2000 pages).
