Purpose of pipe stub in the engine compartment
 

Hi...!Perhaps this is too simple. Anyway, what is the purpose of the pipe stub and its belonging hose outermost to the right in the engine compartment? (pls see attached photo - sorry to say, it is not my car :)http://forums.pelicanparts.com/uploa...1394053045.jpg

It ties into the heating system for providing warm air to the carbs. Works only when the heater lever is pulled.

+1 for Tony's answer. The photo is of a MY68 (air pump - one-year only); here are additional photos from a 'deconstructed' MY68 coupe.
