Almost imperceptible. It was such a small change, that I wondered if it actually changed, or if it was a function of me looking at it at a different angle.

I reassembled everything, and I have had it running into the tank for a couple of hours. So far so good. It is holding its working pressure. We'll see how long the tank lasts.
