    Vacuum Tank

    What the hell is this for? I think it's connected to the HVAC System. Do I really need it, cause I kinda broke the line going into it.

    When there is low intake manifold vacuum, the vac tank acts a vacuum reservoir. Without it the HVAC vacuum actuators will move around every time there's low vacuum (ie medium to WOT throttle.) Did you break the tank or the line? The line can be repair with rubber hose. Find some small enough to fit snugly over the plastic line.

    I never use the HVAC, so I really don't care. I'll keep it in mind if it really starts to bug me.

    you should block off the line that is on the engine side because it will be just like a vacuum leak if the system is open ended. [ actually it is a vacuum leak ]

    Well, yeah, that is obvious.
