There are no listed specs for Torque on any of the bolts for the power steering pump. Recall that Subaru considers this part "unserviceable". There is no kit to buy from Subaru. Just the entire pump.

Look up the price of a rebuilt one from Rockauto. $122 if you exchange it with your core. $162 w/o core exchange.
Its the O-rings that hold the fluid in not the clamping force of the bolts torqued in tension. The bolts just hold the o-rings in place. Plus the housing is aluminum so I'd guess 17 ft-lb and you're good.
