UH: When I pull up, the varios go up... both of 'em.

There's about 2' of silcon tubing in the circuit, all of it at the
panel end. The second line of TE is silicon from the Y splitter that
I installed, so call that about 4' long. The pvc lines end at the
central pedestal where the hood and panel are removable, so there's
silicon, then a 5-way quick-connector and then silicon to the
instruments. I could probably remove about 4-6" of extra silicon, but
it gives me some "play" for being able to get at the quick-connect
without needing extra joints in my arms.

I'm not doing heavy g manoevers, maybe 1.5 g on a pull-up, perhaps
0.75 g on a push-over. The most g I normally pull is during
thermalling turns.

I think I recall reading in the aircraft notes about a Brunswick
tube. It appears to be factory made and the slots are well-defined.
