REFLECTOR: Hydraulic Pump Leak

[Ronnie Brown]

The vents really need to be left open.  You can see the fluid go up and down
in the reservoir as the gear is retracted and extended.  The difference is
the piston rods that displace fluid as they go into the cylinders.  I agree,
seal the vents and you could have a real mess!
