What year or what model or engine? 4 barrel Carters were used from 53-56 and routing depends on the engine.

Engine is a 1952 327 straight eight but has a 4 barrel carb and 4 barrel intake from a 53 or 54. The intake has a small box near the firewall with a cover. I believe the tube may go there but not entirely sure.

Parts says the 53-4 four barrel manifolds are the same so if yours has the box this illustration from the 54 fact book should be the routing.
I believe the box is just a semi closed air chamber. There should be a small opening or orifice where an amount of air is allowed to enter the chamber. That air is never directly mixed with exhaust but is heated by the hot exhaust heating the rear and sides of the chamber. Via a short length of steel or copper tubing vacuum pulls the heated air up into the choke mechanism where it flow around a thermostatic spring. I believe the tubing at the manifold end is unfinished and connection is nothing more than a push in or slide fit into the chamber outlet Not pressed but snug enough there is no appreciable leakage around the tubing where it enters the box.
