so what exactly is this kit?
here is what the TSB I pulled off another site says
Heavy Duty Filtration - MOPAR Retrofit or Add On Parts Available
2004 - 2009 (D1/DH) Ram Truck (2500/3500 Pick Up)
2007 - 2009 (DC) Ram Truck (3500 Cab Chassis)
NOTE: This bulletin applies to D1/DH vehicles equipped with a 5.9L Cummins engine
built after January 1, 2005 and D1/DH/DC vehicles equipped with a 6.7L
Cummins engine built from 2007 model year (sales codes ETH, ETJ).
Several fuel system add-on or retrofit parts are available to enhance the filtering capability
for customers exposing their vehicles to extremely dirty conditions.
Description of parts available for Cummins diesel equipped vehicles are listed below:
∑ 5.9L & 6.7L Water stripping, frame mounted filter kit. This kit includes the following:
revised lift pump, lines, heater, water in fuel (WIF) sensor, and instructions.

∑ 5.9L & 6.7L Add-on or up-graded fuel tank vent hose kit with vent cap.
NOTE: Several parts will be added to this bulletin when they are available. The
bulletin will be revised when they become available. These parts include a
Filter with Bracket assembly which will replace the cap on the fuel tank vents
for all the above vehicles, a 5 micron fuel filter for 5.9 engines and an
improved air filter for 5.9 engines.
NOTE: The maintenance intervals for the fuel filters (engine mounted filter and
chassis mounted severe duty fuel filtration kit filter) maintain a 15,000 mile
service requirement for both.
