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.
