Fuel vent lines, day 2. � Note that all vent lines are 1/2" tubing.

Here, the vent system is completed from the sump tank and both fuel tanks. To create clearance for movement of the gear legs, the vertical vent lines had to be pushed aft as far as possible. In addition, the turn at the top of the vent line had to be redesigned.

The next task will be installation of hard points so that we can secure the vent lines with adel clamps.

A: Vent line exiting the sump tank.
B: Vent line exiting the pilot side fuel tank.
C: This crazy loop was the most elegant solution we could find to 1) gain
� � height before making the downward turn and 2) avoid interfering with
    the retract system.
D: The one way check valve for air supply to the vent line.
E: Vent line on on its way to the exit at the bottom of the fuselage.
