I have a 2013 Ram 2500 Cummins,Where are the better buys on fuel filters? do you always replace both at the same time? At 8,000miles and have 10% left ,Will I have to replace fuelfilters every 8,000 m...
I switched vendors and now buy all filters / Fleetguard from truckhelp.com, their prices are hard to beat. I order 12 fuel and 6 air for both my 2006 Dodge Cummins diesels.
I change fuel filters with each oil & filter change and air every other time unless needed sooner.
