brake servo vac pipe question

[S3 TAM]

Right yesterday I removed my Inlet mani and installed a "Intake Phenolic Insulator Gasket" which I got from Bill "Thanks for Quick delivery Bill".
I also took the opportunity to sprayed the inlet mani and simplified the oil breather system "still waiting for catch can".
Anyway my question is can I replace the brake servo vac pipe from the mani to the the connector near the strut brace "highlighted in red" I have also ordered a 12mm non return valve to replace the bodge job rachet extension bar i shoved in pipe.

your red ovals are quite subtle

sorry i didn't realize you can hardly see them. there on the left hand side top near brake fluid and bottom left of inlet manifold.

yeah i saw them, knowing where the brake vac pipe was...

So can I replace the whole pipe with some 13mm silicone?

i am no mechanic, but i dont see why it would be any different to any other vac hose...
