1940 Continental Vacuum Tank Assembly

[Mike Markin]

I recently reassembled the  vacuum tanks for my convertible and was seeking some advice as to what lubricant to use in the tank.  The plungers have a leather ring around them and the leather needs to be properly lubricated to keep the seal as the air is pushing or let out.  After checking with John Murphy, I have received a couple of suggestions: Neatsfoot shoe oil (may have been originally used) and Marvel Mystery Oil.  Its important that the leather be soaked with the lubricant so that the leather expands.  If you have one that is dried/drying out, soak it over night before re- installing.  As I was installing the plunger I added a couple of tablespoons of lubricant (Marvel Mystery Oil) to keep them operating efficiently.
