I traded my 2008 Ram 2500 with Cummins 6.7L motor an have 4 left over, new in box, never been opened Fuel filters. One is the Mopar MO-634 or part #6861634AA and 3 are the Fleetguard FS43258. Fleetguard is the cummins division that makes the filters for the cummins motors, selling under the Fleetguard and Mopar brands. These filters are $50+ each. Buy 4 from me for th price of less than 3! $150
