Fuel Filters

Has anyone did anything with their fuel filters yet on your ecodiesel? Drained water out, changed, anyone have a procedure for bleeding/filling the filters after change out? I will change mine every fall after this first year. Purchased the Jeep in late July and will wait till fall of 2015 to change them out. Just looking for ideas. Thanks.

Re: Fuel Filters

Planning on doing the same - barring any water issues, I'm aiming for once a year.

Re: Fuel Filters

I haven't looked into the procedure for the GC yet but on my other vehicles (F-350 and Mack dump truck) I do the following:

1. Change the filter when the fuel tank is low thereby reducing the amount of fuel that will flow into the filter area.
2. Open fuel in water drain valve and allow all the fuel and water to drain into a suitable container. I usually cut part of a one gallon milk jug out to catch the fluid which is usually less than a pint.
3. Reinstall the drain plug replacing the O ring if necessary (see # 6 below).
4. Remove the filters according to the instructions.
5. Replace the filters and any O rings that are there.
6. Moisten the O rings with clean diesel by rubbing your fingers over them ( like what you do when replacing the oil filter.
7. Tighten down to specs being careful not to overtighten.

That should do it....

Re: Fuel Filters

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.

Re: Fuel Filters

Thank you Treeguy, Please let us know if you find the fill procedure to be different from what you posted on here. Do not want to get air in the fuel system after filter change out.

Re: Fuel Filters

Just in case you don't have this here is the diesel supplement and on P 82 it explains the procedure for replacing the fuel filters and priming the system...

Re: Fuel Filters

The main mechanic at our dealer said when he went to the class on these,
he told me that they recommended draining the fuel filter water during your oil changes.

The common rail fuel system is self bleeding. No worries with air in the lines
