John,

Sorry to say the factory installation does not work for the following
reasons:
1. The tube comes through the seat pan under the right thigh not in
the center. This causes the tube to be crushed so that flow is
restricted.
2. The tube running down the right side then into the gear well and
onto the aft end of the right gear door has two uphill points ( or high
points ). The Germans must have great nossel pressure. The
corresponding low points leave liquid in the tube with air in between.
The suction created by the tube at the gear door never removes all the
fluid. This requires a pretty good liquid pressure to move the low
point liquid and air out. This can cause a "blow off" of the condom
and if one uses a funnel, it has to be held up close to the top of the
pannel.

system that works for sure.
