I changed the fuel filters on my 2014 Turbo Diesel at 40k miles, mid-way between the A & B driving level per the Maintenance Schedule. I'm a high mileage driver with 53k currently on the truck.
Very simple change-over and I did not let the volume in the tank get low or anything like that.
- Opened the drain plug (Phillips head) between the two filters. About a pint of diesel drained into my catch basin.
- The two filter assemblies use the same size ratchet as the oil filter (27mm I think). They simply unscrew and you will need the catch basin there as well. Maybe another pint between the two filters came out.
- The two filter assemblies screw back in and the drain plug is tightened.
- I forget the process exactly but I think it was simply turning the ignition to the RUN position, without stepping on the brake as you do not want to start the vehicle, to let the fuel pump fill the reservoir.
Not much too it. Good luck.
