Coolant passes through a hose on late model MGB's from the back of the engine goes through that tube which heats the manifold amd the water operated choak on the zenith carbs, then connects to the front bottom radiator hose. Some Weber manifolds have that and some don't depending on the application.

In alabamba you don't need it hooked up. the tube itself works as a throttle return spring mount point if you have the semicircular bellcrank.

reporting the thread to skye so he can move it to the correct forum.
