Here's my question: Why does a car need a vacuum cannister? Mine is broken, it's in a crappy location to access and I want to replace mine. So, I am planning on buying a vacuum cannister and mounting it in another location. But why do I need it?
Right now I have the tube that goes to the cannister shut off. My vents work better, but I don't see the difference between tying off the end of the tube, or connecting it to a cannister.
Vacuum = no air. Tying off = no air. Why do I need to contain 'no air'? If the cannister has a one-way valve to let air escape, why not just a check valve?
So, there goes. What purpose does a cannister serve versus tying off the tube?
