Diameter of Vaccuum hose line

[bilzer]

I am trying to determine the diameter of the vaccuum hose lines on a 2000 Jetta TDI. Can't seem to find it referenced in the bently manual.

Does anyone the the hose sizes?

Go to the second page of the "How to" section and look for a post by Paramedic titled: Silicone hose and viton tubing

Most is 3mm, but some is 5mm at the N75 valve:

Factory is 3.5mm and 5mm.

3mm or 1/8 inch silicone replace the 3.5 just fine. 3/16 is near perfect match for the 5mm.

Idparts had the 3.5mm and 5mm OEM style cloth braded vacuum line. Just bought some to replace mine. Most of my vacuum lines are original!
