There seems to be a bit of confusion sometimes with vacuum hose locations on later models.
I have two pictures to explain how to fit them properly as it can be a source of confusion sometimes.


GREEN , Carb vacuum hose
BLUE , Carb to Airbox control valve hose
RED , Airbox control valve to hot / cold intake flap valve
Its also important that the vacuum hose between the carburettor and distributor has a metal pipe in it high up to prevent any chance of fuel being syphoned into the vacuum unit.
