Hard vacuum line to the carb - questions.

I’m curious about the hard vacuum advance line. All motors? All models? Different styles for different years? What about AIR equipped motors? Affixed with spring clamps at the rubber hose?

Can anyone shed details?

Neither of my SB motors have these so looking to add if original equipment. A BB motor I used to own did have this line.

Borrowed example pics show the line joining the carb on the LH front port.
