This has me scratching my head. If the painted tube is connected to the air cleaner and the bottom of the exhaust manifold it is then part of the choke heat system. But in order for air to flow through that loop to move hot air -to- the choke, it would have to be a positive flow -from- the air cleaner. ---Also, my original air cleaner base plate (oval air cleaner) has no connection point for a tube like that.
That brings me back to a question I had long ago. How is the hot air from the manifold expected to get to the choke to heat it? Just float up?? It needs to be pushed somehow. (In my case I am using an electric choke so it is moot for me).
Where is a positive air flow connection for the upper end of that tube??
BTW this pic caught my attention from my FSM for 69. It's for anti-icing of the throttle plate of the slant six. The flow direction makes sense. I haven't yet found an illustration/pic of the system in question.

The choke has a vacuum port which sucks filtered air in from inside the air cleaner via the tubes which go through the manifold, where it is then heated, and into the choke housing where it warms the thermostatic spring. If you start a hemi up that has the thermostat, but no choke tubes, you will feel vacuum through the choke tube inlet in the bakelite housing.
That means Auggie posted it 1 week ago.Was looking through the list of responses and found this. I don't know what a week ago means.

I disagree. Only one choke heat tube is on that engine in the video.
Found another pic with both choke heat tubes. View attachment 545538
I see what your talking about. The choke tube to transfer heat to the choke mechanism, the insulated one, is there. That's called a choke tube.
The other tube that RC pointed out isn't on Nick's engine. The one that goes to the air cleaner. My question, what year or years did they use that tube? Nick stated a couple of times that he is going by 1969 to 1970. He also said he is useing 1969 carburetors. He flips back and forth between the two years for the application that he might be using on an E body car.

I just checked for his most recent video. Dec.27th, and it was about his shop party, nothing about the hemi.Did Nick ever speak up to tell what was missing on his hemi engine?
If so who did he give credit to?
