Edit: There is a spring and a membrane. Membrane is actuated with the nipple.

Fuel comes from the top and is held there with a spring to 3 bar (typical). Rest is dumped to the left.
If there is a vacuum in the hose, membrane lifts the spring a little and pressure in top hose is reduced. Other way around if there is boost.

I don't know how this thing is connected in your system so I cannot say what will happend. If you connect the hose it will either make your problems worse or flatten the boost/vaccum AFR differences.

If nipple is not connected it will only introduce constant pressure loss across the valve.
Thank you for your time,
