How important is the "Tank Surge" under the intake?

The nipple on my "tank surge" is broken and I was wondering if I can do w/o this item? What exactly does it do? It's a plastic box with nothing inside so is it a simple container to prevent a vacuum surge of some kind? If it's critical, I can try to figure out a way to fix it. 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.

It's item #1 in the diagram below



It's the black plastic box in this pic

no tank surge, no IRIS valve in the intake...

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.

Re: How important is the "Tank Surge" under the intake?

Copy that, I fixed the nipple A simple 1/8" plastic hose mender and plastic epoxy weld took care of my broken nipple (ok, I'll stop with the nipple jokes).

Does anyone have a closeup shot of the IRIS valve? I need to make sure that my orientation is proper before I re-install the intake.

Thanks for the inputs.

Yes, yes, I have to agree whole heartedly
