Just reporting back of current status: I myself did not have enough time to do it (as I was going out of town, the admiral would be extremely upset if I had to change plan) but I had a mechanic to do it for me. His theory was that the clogged filters created excessive negative pressure to allow air to get in from the not-so-great fittings. He changed both filters just so that I can at least get to the home marina; he also told me those lines and fittings require further work once I am there.
I will certainly put a few gauges as suggested when I get into it. Thank you all for your advice.
