Great to see a thread finished with a fix.
On the idea of fluid lines into the cabin. Didn't we use capillary feed into cabins for the purpose of instrumentation measurement from early last century till the 1980’s? Such as oil pressure gauge- some 80 years!
In my early years we would run copper lines from the engine rooms of ships to the bridge, runs which were a good 300feet and those things somewhat vibrated. Sometimes we coupled in a short length of annealed copper where there was excessive vibration and wrapped them in asbestos where there was heat.
