Question Check valve and Air injection shut-off valve

Can you tell me where the Check valve and Air injection shut-off valve that work with the AIR pump are located? How big of a deal is it to replace them? My AIR Pump is shot, so I'm going to replace it, but I've been told these valves should also be replaced at the same time. I have a '92 300E 4Matic.
