Vacuum diagram 1991 SL 500

Where would I find a vacuum diagram for a 1991 SL 500?

Are their vacuum line kits availble for sale out there ?

Any help would be appreciated !

There are two systems on the SL500 One for the engine and emissions control and one for the locking system with a pump located in the trunk. I am hoping a Star manual I have on order will have schematics on both.

Years ago I purchased a 65 Coupe De Ville near Los Angeles that had the Smog Rubber Rot problem so I think I know what you are going through. Got a couple meters of hose and replaced all the rubber under the hood. Good luck and let me know if you find anything.
