Water in Fuel? When Do You Drain the Filter?
Hi diesel noob here again LOL....so I'm considering taking the plunge and buying my first diesel, 2015 Ram 3500 with 6.7L Cummins and 81k miles. Reading through the Diesel Supplement to the owner's...

If you get bad fuel you might get that warning. I bought my truck with 70K on the odometer and I've now put on 79K of my own. In nearly 5 years of ownership I've never had the WATER IN FUEL light come on. I've only ever touched the filters when I do my annual/15K mile oil change and fuel filter replacement.
Some cheap insurance would be to keep a 10x10 tarp under the back seat and a small plastic cup if you have to do this in an emergency situation. The rear filter is directly over the drive shaft and when you drain it the fuel hits the shaft and goes everywhere. If you place a small cup under it you can catch the fuel and avoid a mess.
Also, the front filter drains directly on top of the front axle. I attached a piece of 1/4" rubber hose to mine and routed it up by the radiator. This makes the outflow easier to see and also avoids a mess on your axle.
