Which fuel filter for my 2012 Ram Cummins 6.7
 

Which Fleetguard would b best for my truck 10-18 6.7 fs53000. R the fs43255 10-12 6.7. Fuel filter. And was thinking about adding a water separator filter on it as well. Looking at what they did for the 2013's and up and where they mounted it as well. any idea's on that.

This is what I order and use. It is a water separator already, all together.
