What are these things???
What are these things???
Above the brake booster there is a cylinder thingy with a vacuum hose on the bottom, then it has a foam "filter?" I also saw one in the drivers side just above the vaulve cover. I cleaned the foam because it was covered with mud, but what are these things? I feel retarded now since the only way to explain this is thingies.
I will try to get my dig camera working. They are about as big around as a silver dollar, and about 6" tall. The vac hose comes in the bottom it has an electrical plug on the side, and a cap that has foam under it.
