I'm replacing some of the old hoses that come out of the oil separator after they split at the tee into different directions. They are hoses 61 and 62 on the diagram. Part number in PET looks like 999-236-002-51 designated as 12mm oil hose. Has anyone found an equivalent that can be used from a typical auto parts store or do I need to order this from one of our suppliers?
No. But after I posted I just searched 12mm oil breather hose and saw lots of air-cooled VW links of hose that you can purchase by the yard or meter. The Porsche hose is spec'd with a 3.5mm wall thickness. The VW hose is 3.3mm wall thickness, but I doubt 0.2 mm is going to amount to anything when is comes to a rubber vent hose.
