DON'T GAMBLE WITH AFTERMARKET FUEL FILTERS, BUY THE ORIGINAL EQUIPMENT FILTER AND STILL SAVE MONEY!!! This is the OE fuel filter manufactured by Fleetguard for the 5.9L Cummins turbo diesel used in the 00-07 Dodge pickups. It has a 7 micron filter with special filter media treatment for advanced water separation. Because of their superior design, filtration, and water separation abilities, Fleetguard filters earn the right to be installed as "original equipment". Aftermarket filters don't have the same durability, water separation abilities, contaminant filtration capacity, they don't provide engine damage warranty if they fail, and are frequently more expensive. That's why aftermarket filters are not installed as original equipment. For more information, please visit this products webpage.
