I have a 2012 Ram 3500, 4X4, Crew Cab, 6.7 Cummins. The original engine mounted fuel filter was a Fleetguard FS43255. That filter apparently has been upgraded to the new Fleetguard FS53000 NanoNet fuel filter that now filters down to 3 microns instead of 5 microns and acts as a water separator.
My question is, is there another filter on the frame rail? My local dealer says there should be, but if there is I can't find it. Where abouts is this "second" filter located on the truck, or does it even exist? The next to useless owners manual doesn't say anything except "the filter should be changed every 20K km or 12K miles." It does mention that there is a petcock on the bottom of the filter housing to drain off water, which makes me think there isn't a second filter! I f anyone out there can clarify this for me I would be very appreciative!
