New OS is cheap (50 to 60 dollars usually) and most probably one of the hoses or their o-rings will fail during the removing process, so I guess that the best way would be to replace it with its hoses, worth it when you spend not less than 3 or 4 hours to do the job (at least for me!).

I believe there is a seal kit available for the separator (at least some models of it). I agree that when it is opened up, if it needs seals then it is a choice of resealing it or replacing it. My intended comment was that if you have new parts on it, it isn't necessary to replace it every year, but rather to clean it out. It does have a finite life, however, and at any piont replacing it may just be easier.
