Default What sizes vacuum tubing for a 1994 960?

I want to basically replace all of the vacuum tubing under the hood/bonnet and also that feeding to the inside of the car, where vacuum is used on the climate control system, with silicone tubing.

What sizes mostly do I need? I see silicone tubing in 10 foot lengths commonly available. But before I spend between say $15 and $20 per 10 foot roll, at least one roll for each size, I want to ensure I get what I need and especially no size that I do not need.

Also did Volvo use metric size tubing and do I need that for the best fit in some cases? I know how to convert SAE/Imperial to metric and I know a few sizes that are nearly identical between the 2 systems. I just thought if someone else out there had already done this job, I would like to benefit from the time you spent figuring it all out.

I believe most of the common vacuum lines on a Volvo use 5mm ID.
