It’s probably me or my computer, but I have no pics or diagrams coming in. ANYONE ELSE?

Wade may be on this board. If so, I want to thank him again for the fine work.

I am being serious this post...
I couldn't see the pics, but you confirmed how I thought Chuck had plumbed his tanks.
I agree that way provides active deaeration and it will be one of the few modifications I plan to include.

This (below) is a genius modification, creating a true active deaeration system using suction from the water pump to continuously flow water through the expansion tank, drawing air from the high points in the system.
But how common, how many have built a system like this ?
The TSB modification, which some here ( Tomas? ) have confirmed was likely incorporated at the factory, connects the relatively high-pressure swirl tank to the lower-pressure radiator, so I conclude while the engine is running, nothing is going to flow from the radiator to the swirl tank, it's not going to actively de-aerate. Initial fill, I can see it helping. After that, I'm scratching my head.
Thanks,

There is definitely a mod that sucks air from both the swirl tank, and the top of the radiator into the expansion tank. The expansion tank is under suction, and this causes any trapped air to bleed to the expansion tank.
I did this on my car.
I believe that it does its job, especially of removing any trapped air from the radiator.
I had to run a new, separate metal hard line down the length of the car from near the front of the radiator, all the way back up the bulkhead past the electrics panel, to near the expansion tank.
Here are pictures of my tanks with the appropriate bleed fittings installed.

I'm kinda fascinated by this mod, which I believe is in the TSB's,
connecting the top of the radiator to the swirl tank with a long
hose. Not sure how it works or what it was supposed to do.
With a completely dry system, I can visualise how it would allow the
radiator to fill completely, as air formerly trapped in the top of
the radiator would have a path back to the swirl tank, a higher point.
But once the engine is started, water or air is going to move from
the swirl tank to the radiator, because of pressure difference. Not
sure this is helpful but maybe isn't harmful.
Most difficult to visualize, if the engine is off and there is air
in the radiator, can the weight / head / row gee aych of the water
in the swirl tank push the air into the swirl tank ? Is there some
Archimedes rule I'm not seeing here ?
Also did any cars come from the factory this way, was there an
official path and mounting systems for the hose ? Cable ties ?
Thanks,
Guy D.
