My Ram only has one as well, but I think lineman is referring to the water separator as another fuel filter.
You have one canister style in the rear under the bed, drivers side, with water separator, and a drop in under the hood also with a water separator, both have sensors that will tell you if one or they have water in them, and can be drained out easy then changed soon as possible. Both are fuel filters and water filters.
Having 2 filters the fuel and water better than one. Injectors getting water or dirty fuel can be bad, and it is very expensive to replace an injector or all. The older rams and the chebys and ford people do a cat conversion to add double filters to filter better than the one.
Do you do your own oil and fuel filters changes?
