Dont ever drive ur Subaru if u discover any fluid aeration problems. Ie air leak in p/s system with fluid overflowing the resorvoir. The pumps are very sensitive to any cavitation and driving the car even what u consider a very small distance will most likely render ur p/s pump buggered.
I found this out the hard way. Get the car towed, leaks fixed with new o-ring(top of pump), new hose clamps on low pressure hose and even a new flexible hose(pirtek or similiar), then top up ur fluid and bleed with wheels off the ground turning lock to lock. Making sure its all working well before driving. This might just save u a costly pump replacement.
