Unfortunately we are still without our access to the Stellantis database to source the diagram and part number for you. however hopefully one of the members with their own access may see your post and help you out. :)
I used to be indecisive, now I'm not so sure!

I can’t find it on the diagrams either, tbf.

I think the pipe work is shown on the “Gas Recycling Circuit” (the egr system). It’s item number 5 on that diagram and runs from the vacuum pump to the vacuum chamber reservoir and a couple of electrovalves. However that pipe doesn’t include the plastic manifold that is the item you’ve repaired, only from the rubber 90degree bends, on.

It’s not on the vacuum pump diagram either, which just shows the valve on the pump, with a single outlet port - which is the other thing your plastic manifold attaches to.

Frustrating. Seems to drop betweeen two diagrams!

From the photo though. It just looks like a fuel pipe quick connector, with several ports.
Something like this (but with more ports).

Perhaps if you search around for those type of connectors, you’ll find one with the right number of ports?

Nope it is definitely some sort of a T-junction one for the brake servo, one for the Turbo VNT actuator, one for the Throttle shutter ( swirl flap motor ) and other one is most likely for the EGR valve actuator but since i am not first owner of the car and i think EGR is blanked out and DPF removed so that is why is missing a pipe or maybe the empty one is evaporator i don't know i am confused but i definitely want to replace this part with a proper one.

Yes. That’s what I described.

I didn’t mean it was a fuel line, I said it “looks like” a fuel line quick connector with multi ports. Ie they’ve used (what is normally also used as) a fuel line quick connector on the vacuum line and therefore try looking at those to see if you can find one that matches.
I think it would be called an “F” type (because it has three ports shaped like an F).

If you don’t like my suggestion, then don’t follow it though. Up to you.
