This leads me to suspect all the tubing (and maybe the 'T' connectors too), so I plan to replace them ASAP.

Do not use the clear poly tubing from your local hardware store. It loses its flexibility over a short period of time and that can cause leaks.

But quality tubing from one of the glider suppliers. I know that Wings and Wheels stocks this tubing but other glider outlets do also.
