Anyone advise the correct seal to replace for the reservoir in the 638082-A hydraulic power pack assembly?

Been having extended pump running on power up and eventually found the seal between the reservoir and the pump protruding and oil leaking out as the pump ran.

Been trying to chase up the correct replacement seal here in Melbourne (Aus), but having the devil’s own job trying to find the correct seal.

Dom,  The problem may be the reservoir top flange being out of round.  Mine was out of round .100” and the replacement was no better.  I rebuild the second tank making my own top which fixed the problem and eliminated the air-cleaner stud going thru the bottom of the tank as well.  Not sure what will make an out-of-round top flange seal but I know an o-ring won’t.
