AC vacuum hose question

Hi ! I am redoing the A/C system in my 72 and want / need to replace all of the small vacuum hoses that control the actuators , heater ,valve , etc.

What size is that hose ? How much does it take to replace it all ? I believe there is a vacuum routing diagram in the manual . Most of the hoses are MIA so I don't have any idea how much I need.

Thank You in advance for any and all information !!!!

Have a great day !!! Tom

I believe the nipples are 1/8". So, next smaller hose size should do the job.

Hose is cheap....buy yourself 15'-20' and you should be in good shape to do all of it without an issue.
