Hidden vacuum source
 

Hey all, i have another one of my weird quessies! :D
Today i started work with my dad, on my beast to find out why my heater is always on. amongst other things, found and corrected, we discovered a vacuum reservoir cannister in the passenger side wheel house. It is not connected to anything, but has two nipples for hoses? on the inside of the engine well. I would love to find out where it is supposed to be connected to!! Would it be the mannifold?. Any help would be GREATLY appreciated! Thanks in advance!:D

If it is the one i think you are talking about one side go to the manifold vacumn with a check valve inline and the other side go to the vacumn operated motor for you ac/heat blend door.

Thanks Shaggy!, i'll check that out :)
