the filter for the powersteering is now incorporated into the black plastic reservoir mounted on the pump. You have to replace the tank to change the filter (like when changing the rack or worn pump)

the recommendation is to fill the reservoir with fluid and let it soak for about 15 minutes to prevent hydraulic blowout.
