1600 CT Aircooled vacuum lines question
Posted: 09 Sep 2026, 22:03
Hi all,
A 1600 CT question: I'm replacing the vacuum lines around the carbs, distributor, manifold and airbox and looking at my airbox I see two connectors for the vacuum lines.

However Mr Haynes shows four! Two being labelled as Temperature regulator and two as Temperature switch. I reckon the airbox in my bus is original so it has survived with just these two. Are there any CT experts left who could guide me in what to connect to which?

I hope that I'm making sense.
Best,
Paul.
