Vacuum line sizes for '01 B6

[vadim]

I am planning to replace all of my vacuum line (as preventive maintenance) next time I do a carb sync. What size lines should I use for '01 B6? Also, the fuel line is 3/8 inch, correct?

Thanks,

P.S. Searched all the posts, couldn't find anything on vacuum lines. Sorry if this is a repost

Hmm, I guess there's a reason why I didn't find anything when I searched.
