Yes, and I changed it.

Filter p/n: M2000-97891
Cost: $4.36 at Fastlane

The procedure is listed in greater detail with photos in the Diesel how-to sticky, but here is the cliffnotes version:

1: Open your power steering pump lid, set the lid and wingnut aside. Gently release the lockwasher and spring, and slide them off.

2: That thing with the holes in the bottom is the filter. Leave it in for the moment.

3: Move your washer fluid tank to the side for the moment. Put a large (at least gallon) catch container in that spot.

4: Disconnect the pump return hose. One hose has a high-pressure fitting, the other has a hose clamp. The hose clamp one is the return hose. When you disconnect it, fluid will spill from the hose, and from the pump. Catch it in your can (if you can ), and direct the hose into the catch container.

5: Have at the ready three quarts of PS fluid. Two quarts of cheap stuff, and one quart of whatever boutique PS fluid you want. I used Valvoline SynPower. They make one with a 'stop leak' stuff in it if you are having leak problems (though the stop leak things rarely stop anything but the tiniest leaks).

6: Have your beautiful assistant fire up the car, and begin turning the steering wheel lock to lock. They don't need to turn it fast, or slow, just a modest speed. As they do this, pour a quart of cheap fluid into the pump slowly, as it gets sucked through, pour in more. Then pour your other quart through. The fluid will move through FAST, so don't worry. It will also spray with some force into your catch container. I used a narrow mouth bottle to limit splashing. By the end of the second quart, your fluid should be coming out clear.

7: Have your beautiful assistant stop turning the wheel, and shut off the engine. Fish the filter out of the pump, and slide a new one in.

9: Reconnect the return hose to the pump. I used a shiny new hose clamp, since I don't trust super-old clamps.

8: Reinstall the spring and lockwasher. Pour some of your 'boutique' fluid into the pump, and let it bubble down. Add some more and bring it up to within about 1/2" of the lip of the reservoir. Fire the car back up, and have your assistant go lock to lock a few more times. This will bubble and foam as the fluid goes into the system. The level will go down, so top it back up again. Have your assistant turn a few more times, and top up again if necessary. When it stops bubbling, your system is bled. Top up one last time if necessary, and put the lid back on, and tighten the wingnut.

I ended up adding most (but not all) of a quart to the system. I don't know the exact capacity.

9: Return the washer reservoir to its nook, dispose of your bottles and filter, and have a beer. Marvel at the gunk in your catch container. Damn, that was in your power steering the whole time. Gross. Have a beer, you just spend 20 minutes on an easy task (didn't even have to bend over).

Hope that helps!

peace,
sam
