Shop says I need a new pump. It did not leak before I had them change the oil. Is this no-ring a common leakage issue? I'd rather try a $5. fix if it is common rather than a new pump. From what I see one bolt and the o-ring itself must hold the reservoir in place, is this correct? Thanks

 

Has anyone changed their reservoir? It seems that one bolt and a clip(hope it can be reused) hold the reservoir in place. I have a new o-ring and a new reservoir. I can see where the clip would go but did not see them on ebay or would have have gotten one. I am hoping this is an easy job due to my crumbling back. Mark
