Default vacuum source tube a/c control 1980

HI there, my buddy cut his vacuum feed tube to the a/c control in the cab so it won't move the vent from floor to face lol. that tube is super thin. anyone have a part number? I've highlighted in yellow which tube it is.

you don't need the whole hose. you need to find out where the hose is broke or disconnected.

Engine compartment side HVAC or cabin side all the vacuum lines are the same size.
The easiest way to couple the two is with a section of 1/8" I.D. vacuum hose.
I also had to repair both the Hot Water Shutoff line (White) and main Vacuum In (Black)
Just make sure it is rated for vacuum and is 1/8" I.D.
Most local auto parts stores will carry vacuum hose.

we used to cut the end off the inside of a ball point pen and use it to patch broken vacuum ports on saabs. and there is very small tubing available from lowesdepot. you have to find the whole vacuum hose before you can replace it. usually points out where the patch needs to be.
