 Thanks for the details Chris,
 I just think it is a bad design. Can you tell me if the system is designed to
have only one side pressured at a time(pump off? Is the low side supposed to
be vented to the resevoir . If so mine does not act that way. Both sides seem
to be sealed up when the pump is off. That appears to be true with the gear up
or down.
