I know zilch about these also but just this week I carried one to a shop if you need parts it could possibly still be available. It belonged to a friend who saved good parts from his 220D (including pistons, cam, etc) He gave them to me when he moved away recently. if interested in the pump PM me. I don't check into the forum regularly but Emails get forwarded to me, so if you have some questions I can ask the local hop where they USED to rebuild these, sadly that is no longer the case. Reid
