Attaching only one distributor vent line?

I'm not at all sure what you have done, when reading your post, sounds like you may not have it in the right location.

It is a push pull system and for it to work the circuit can not be broken so you most likely will not detect any air flow but you can add a vacuum gage to see it function.

Charles, I replicated the factory distributor/coil venting on my straight intake with a K&N filter. The fittings might be a little further away from the carb since it is a 6" straight pipe and I had no 90 degree bends. I wanted to see how much air flowed, so I disconnected the line from the fitting facing into the air flow, and I could not feel anything coming out of it. My original air cleaner elbow does not look exactly like the one in TM 9-8030. On my elbow, the vent lines are on the rear side, and nearly at the same height. The holes are on a flat section of the intake and the first is one inch from the end and they are about 1 1/4 apart.

Has anyone here actually felt how much air comes out of the airflow facing fitting on the air cleaner elbow?

Thanks hb. I realize it is a closed loop designed to work in conjunction with each other. I am just curious as to how much air flows out of the one forward facing fitting. I was underwhelmed by the airflow coming out of that fitting. I am just going to assume there is air flow when everything is hooked up. I am not sure how I would add a vacuum gauge to the system, unless I used temporary lines.
