Now that I've eliminated the leak in the step slide I'm down to the air compressor running about once per 20 hours more or less. Now I have an interesting leak down situation. All three needles (2 brake and 1 supply) drop in unison. So, either there remains a leak in the systems from the supply tank and bot check valves on the two brake tanks are back flowing at the identical rate, or there are equal leaks in each of the two brake systems, or there is some common place where the two brake systems somehow come together and a single leak could effect all the pressures equally. None of these three explanations seems plausible. It's a puzzle that I'll be noodling on for a while it seems.Given the leakage rate it's not like this is an urgent problem. Actually, if it was just the leakage rate I wouldn't be bothered. What bothers me is I can't figure out how the leakage pattern is possible. I hate being stumped, it's one of my several mental obsessions.

Any thoughts?
