New owner question

Vacuum hose replacement. Anyone got a list of sizes and quantity to buy for replacement. My new to me 79 has original vacuum hoses and I'd like to replace the ones that are shall we say crunchy.

I have a '83 SC with CIS

In the engine compartment most of the hoses are 3mm (inside diameter).

You can by non fabric hoses at any autoparts store by the foot/meter.

If I recall from memory, 12-15 ft was needed to replace the vacuum lines.

Perfect! Thanks for the info. Now to get started on the winter project.

Thanks!
