The gas tank in a 1967 Chevelle is vented..Just restoring mine..
A vented gas cap vents the gas fumes into the atmosphere. A non-vented cap system routes the fumes thru the engine to be burned.

NO
Yes
no but a vented cap will.
No, it's usually a vented cap design.
As long as you make certain to purchase the same type of cap you are replacing, it will have no effect. Either "vented" or "non vented". should be marked on the cap.
No the cap is vented and push any unwanted coolant out
There will be a removable cap, or breather on the valve cover.
Yes! It comes with, and has to have, a vented fuel cap; otherwise the tank will pressure up and fill cylinders full of fuel, causing serious engine problems.
No. The vent hose is under the tank
