yes its right where it is in 17

Do not dispose of fuel in the household refuse or the public sewage system. Use an authorized waste disposal facility.Your vehicle has a diesel fuel conditioner module. The module is mounted between the outboard side of the fuel tank and the frame rail.
Note: The module is at the front of the fuel tank or at the front of the aft-axle fuel tank on some models.
You should drain water from the module assembly whenever the warning light illuminates or a message appears in the information display advising you to drain the water separator. This occurs when approximately 6.76 fl oz (200 ml) of water accumulates in the module. If you allow the water level to exceed this level, the water may pass through to the engine and may cause fuel injection equipment damage.
Filter Location
Use the tables below to find the location of your filter.

We have a round cartridge also, it's in the engine compartment. The fuel filter kit for 2017+ comes with both filters. Be sure you order the right one. 2016 won't work on 2017+

 

The owners manual says something about draining the filter every 30 days or so, I drained mine after 5000 miles, perfectly clear and bright, no water, no sediment.
I used to do fuel samples on aircraft, take a quart Masson jar, fill abut 1/2 to 3/4. Lid it, swirl it around to make a tornado looking shape. All water and sediment will settle to the bottom middle of the jar.

It does dribble out of that drain, not a steady stream,
