Vacuum hose

Areet
I recently fitted a fmic to my mk4 gti. When removing the old hot side piping there was a black rubber hose connected to the top of the alloy pipe.
I dunno what to do with the hose, can I blank it or does it need connected to my new hot side alloy pipe?

Here's a picture of the hose in question


Thanks

That should not be blocked, it should be connected back to your charge pipe

That pipe is for the boost controller (n75 valve) if you block it or dont connect you will have serious boost problems
