Even though no changes were made to the CP3 with the advent of ULSD fuels, Dodge/RAM did change the canister fuel filter (engine mounted) for the 2010+ trucks. The filter used on the 2013+ trucks superceded what was used on the 2010 to 2012 trucks. The filter has 2 elements built into it, outer element should handle down to about 10 microns along with water strainer and the inner element should handle down to 3 microns. Vast improvement over the previous fuel filters. Erosion or contamination at the injector tips were a problem with the older filter setups I believe.
Also wanted to add that Cummins/RAM were very proactive with fighting water contamination, as both filters (chassis and engine) have water separators and drains. Quite a pedantic setup for OEM, especially considering Ford and Chevy don't have this setup.
