Vacumn line ?

Hello - does anyone know what this vacumn line is for? Any info or diagrams would be great thanks

I'm gonna say the vacuum controlled shut-off valve in the heater hose line.
Looks a lot like a vacuum canister on an old school distributor...sorta of

Yeah I agree. The other vacuum line running parallel should be going to a vacuum ball which then runs to the intake.

Thanks boys, I think I figured it out - that line in my hand goes to the valve on the heater hose, the pink one with a T connects to ball resovoir that runs to the cruise control canister and the right side runs to the intake . If that’s incorrect, please someone correct me..
I’ll try and snap a photo tomorrow in the daylight

Maybe it depends on the car model and options but on mine the tan goes to the valve and the purple goes to the vacuum ball. The larger line on the ball is the vacuum feed from the manifold.

The short answer is the line you have in your hand goes for my car.
All kidding aside, Tan goes to the heater control valve on the intake (or inline heater hose), the Pink goes to that round ball and a Black one goes from the round ball to the intake manifold vacuum port usually behind the carb.
