Silicone Hosing-what sizes for doing pipes under manifold and any others?

[LD3]

Got a boost leak somehwere and there is oil on one of the pipes with under the manifold where they crank round on the left side.

I have bought the Forge silicone breather hoses and the N75 and ancillary boost hoses to be fitted, and already have 007p, Cam cover breather hose and TIP fitted. What I want to do now is get the other miscallaneous pipes done in silicone (at least the ones which are on their way out).

I have heard that 3/4mm is are the main sizes, are there any other sizes I should be buying too?

She's booked into to APS week after so want to take the silicone with me too and get these boost leaks done once and for all!

i used 6mm vac pipe for n112 etc, and then one vac line underneath goes to the pcv valve which is 10mm iirc
