1982 Mk1 Golf 1.8 K-Jet Vacuum System

Hi All,
Apologies in advance as I know this has been covered before but I am still unsure on the layout of hoses for the vacuum system on my Golf. Especially the hose that come from the Vacuum Non Return Valve. I know that I have a hose/tubing going to the Instrument Cluster, but a little unsure as to what else should be supplied.
I have looked on various exploded views and I cant work out exactly what I should have.
Would welcome any clarity on this.
I am also trying to source a Vacuum Non Return Valve as I believe that the one fitted to my system is incorrect.
Thanks
