part of the fitting on the "run". This gives one straight up and one coming
out at 90*. Straight up used for going up the strut and 90* for cross line.
You could take two lines up one side or just one up each side. The fitting
may even work better if it was on the side..just below the T rail than on
the top deck. Another way would be to take the tee'd (front and rear
cylinder feeds) lines (inside one float) and terminate them to a pair of
thru fitting located in the area that is hidden by the spreader bar
(probably one front and one rear of the stub). On the opposite float you
would have to tee the lines a second time and then thru fittings to the
spreader area and another thru fitting to go up the struts with a pair of
lines. You would need to use flex lines inside the spreader bar to give
enough extra length of hose to install them and then put the spreader bar
into place.

Does anyone ever join the retract lines left to right through the
spreader bar to reduce the cockpit plumbing a bit ?

Pretty much the same drill if you use either metal or plastic lines for
the
'phibs retract system. With the plastic...I bring the lines under the
fuselage and T them there in the center and up thru the floor to the
selector valve. This way when you drop the floats...selector to
neutral/locked get inside while someone holds the tees outside and undo
the
in/out lines and throw a union on them joining them together. No more than
a
few drops of fluid will hit the cloth you put down as with the selector in
neutral air can't get in to let fluid out. Now that the lines are joined
tuck them up under the panel for wheel flying..with no worries if someone
hits your pump or selector valve. Heck give the nervous flier something to
do and select gear down and let them pump for hours as the fluid goes
round
and round.
With metal lines I use a 90* bulkhead fitting for each line, on each side,
a
few inches foreward of the fwd strut pickup and then tee these lines up
behind the panel and then to the selector valve. Same drill
again...selector
neutral..pull the lines and put a flare fitting cap nut on each one
without
losing a drop of fluid.
