This is the second unit I picked up from the junk yard but the nipples are ever so brittle.....

There is a check valve in this circuit so if I were to bypass this plastic box, I will reuse the check valve and run the vacuum lines like they're suppose to run - just no "tank surge" plastic box in the circuit.

The system produces the strong torque from 2200 to 4000 rpm. It changes the inlet manifold from a dual Inertia system to a Plenum resonate system, by using vacuum to open the butterfly between the two halves.
The vacuum tank is necessary, as when the throttle is wide open, there is no vacuum in the manifold to work the valve. The tank stores the vacuum to open it, no tank, no low speed torque.
