The accumulators are semi-circular. Both hydraulic fittings are on one end and exit the sphere more or less 90 degrees from eachother. The big one was easy to get around. The smaller one was the difficult one, this is the one which actually goes to the actuator/ lever mechanism, and this is the one which you will want a #11 flarenut wrench for.

I decided to replace the filter, too, it's pretty inexpensive and good insurance.

I ended up using around 2.5 liters but I'll continue to monitor over the next few days, it may require more.

I put the car up on ramps. Be prepared, once you relieve the pressure, it will drop significantly and it's pretty tight under there. Another forum member said that it only took him 45 minutes. I'm only a moderate DIY'er and, along with the glitch I ran into, it took me around 4 hours with replacing the filter, loading up the cargo area, adding fluid, and bleeding the system.

Good Luck!
