VW BORA HOSE DIMENSIONS

[Wezyndrome]

HI I need to replace my vacuum hoses and wondering what diameter silicone ones I would need my engine code is AJM and it's the hoses coming from egr and things. I'm really not mechanically knowledgable and not sure what mm inner diameter to get, some say 3mm some say 5mm

There are two different size hoses - most of the hoses are 3mm; a few lengths are 5mm.
