How about the LML? I still have orig. filter and have 44% life left?

How hard to change is it?

LML filter comes out thru the wheelwell after dropping down the rear of the liner.

LML recommendation is maximum 2 years or 22,500 miles or DIC reading, whichever comes first.

If you want to change the fuel filter
yourself, here's how to do it:
{WARNING
Diesel fuel is flammable. It could start a fire if something ignites it, and you could be burned. Do not let it get on hot engine parts, and keep matches or other ignition sources away.

First, drain any water from the filter following the procedure for draining water listed previously.
The vehicle's engine must be off until the end of this procedure.
The fuel filter is located in the engine compartment on the passenger side of the vehicle.
1. Apply the parking brake.

Access the fuel filter through the passenger side wheel house opening.

It is not necessary to remove all of the wheel liner fasteners.
2. Remove only the necessary fasteners to allow the rear of the wheel liner to be lowered enough for fuel filter access.
3. Unplug the water sensor wire connected to the fuel filter and unscrew the filter element.
4. Remove the filter element. If there is any dirt on the filter sealing surface, clean it off.
Remove and reuse the water sensor float switch located on the bottom of the fuel filter.

5. Install the new filter element.
6. Reinstall and tighten the filter container and reconnect the water sensor wire to the filter.
7. Reposition the wheel liner.
8. Install and tighten fasteners.
9. Use the fuel filter priming procedure earlier in this section to prime the fuel filter.
10. Start the engine and let it idle for five minutes.

Check the fuel filter and air bleed valve for leaks.
11. Reset the fuel filter monitor.
