Are you sure it is not the shaft seal, behind the pulley, that is leaking? If your canister is bent, warped, kinked or has deep scratches in any way the O ring will have a tough time sealing that area. I'd check and be sure that the seal on the pump shaft is not the culprit.

The prices are reasonable and they rebuild and return your old unit.

Any suggestions on what to do about the o-ring on the pump that is supposed to seal the reservoir. I replaced the o-ring and still have a small leak. Thanks in advance. 300 regards...George Ver Berkmoes [Non-text portions of this message have been removed] ------------------------------------ To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx To unsubscribe from this group, send an email to bob@xxxxxxxxxxxxx or go to http://autos.groups.yahoo.com/group/Chrysler300/join and select the "Leave Group" button For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm For archives go to http://www.forwardlook.net/300-archive/search.htm#querylangYahoo!
