Afraid of the answer.....

To bring this story to a close, two coolant tanks later (I was warned about not getting a Porsche tank after the first one which was not) the problem was solved.
The original tank went bad.
I had an "off-brand" one installed, which has a hairline crack in the seam on the side and sprayed a fine mist of coolant onto that "pad" in the trunk.
I then had a Porsche tank installed (#2) and that problem went away.
Lesson learned - the $100 I saved by not buying The Porsche Tank cost me a lot more than that to have it replaced.

While your temperature sender apparently needs to be changed I think we still need to verify the leak issue. I have attached a few pics since they're far better than words. So to be clear, your leakage looks exactly like the last pic in the thread I attached yesterday? From the same hose? Maybe this is simple but long range troubleshooting and assumptions don't work. You can verify by having someone pour water into this area while you observe it draining out the hose from below.

In this image I am pointing to the drain. As you can see the only sources (normally) are the cap and the purge/bleed valve.


In this image you can see the tank is two pieces bonded together. The forward nipple is the nipple for the drain to the manifold where it passes thru the trunk. If you look closely you can see that this nipple has very little clearance between it and the tank. There is a possibility this seam has failed here from the overpressure and is leaking coolant. If you can with engine running,and coolant leaking, look down into that hole and see if coolant is coming between the seam. As long as the cap and purge assembly are not leaking, then this really is the only point coolant can drain to that hose.

And a lot of time spent chasing tail...this was post #80. Thanks for the closure.
