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.

Regards,

Bo
