I have replaced both the top & bottom breather hoses that connect to the AOS. The both have o-rings on them. Never replaced the o-ring unless it was bad and dont believe any of the writeups suggest it either when doing just the AOS.

btw...you do not want to have to replace the lower hose, it isn't an easy job with the engine in the car.
