I'm in the process of installing the 1-1/2" hydraulic pressure
gauges at the front end of the cockpit tunnel in my L-235. I tee'd
into the two lines under the pilot seat and ran some 1/4" 5052-O
tubing diagonally up into the tunnel. I knew from experience that
when I needed to end up with two short but multi-bend pieces, I
should order twelve feet of tubing; So I did.  I must be getting
better after all these years because it only took me two attempts to
bend and flare the low-pressure piece with three bends, and three
tries on the more complicated high-pressure piece with four bends -
and I still have six feet of tubing left! LOL!



You can see in this photo how I had to stagger the gauges to avoid
interference with the elevator push rod and stick crossover weldment
underneath. I also had to flush-mount the gauges so as not to
interfere with the primer pump. I covered the gauges with blue tape
and Vaseline and used them to mold the flox closeouts for those
1-1/2" holes. When the tunnel cover is painted, this installation
might actually look semi-professional!

The high-pressure gauge was more of a problem because I had to use a
90° elbow on the back of the gauge to keep from hitting the elevator
push-pull tube underneath. Thankfully, it looks like it may all work
out when the $35 AN916-1 brass elbow arrives from ACS. (Why the heck
do AN brass elbows cost so much???)
