I thought some of you might learn from my mistake...

We were cycling the gear for the first time in several months and when one of
the UP cycles began, the fitting at the pump blew off.  I pulled the
breaker but
not before plenty of fluid spewed everywhere.  What's interesting is that the
tube had pushed back out of the fitting.  This was one of my first flares and
evidently I had not flared it enough.   The mess is substantial so get the
system all worked out before your expensive interior goes in.  

Another interesting thing.  I had two hydraulic pressure gages installed on
the
panel (one for up and the other for down).  As you can imagine these tell
quite
a story as the gear goes up and down.  As many of you know, when you get new
instrumentation it takes awhile before you gleen all the new possibilities.
 For
now, it looks like the pressure switches were set correctly.  The down circuit
holds pressure much better than the up circuit at the moment.  And a leaky
sequence valve on the right gear door has given itself away on the gage!
