Hey guys i recently changed my vacuum pump out because it was leaking at the O ring from the front cover. After i changed it, i found an O ring for the pump (not BMW), and changed it. It should be good to go. The pump itself worked great. I'd be willing to let it go considerably less than what BMW whats for a new one. 150$ shipped anywhere in the continental US OBO. Would like to sell it, as i have no use for it anymore.
