 Gary,
 Count your blessings man!
 Try a 3 or 4 hr flight at 17,500 and decend into Vegas or PHX. That would
definetely tell you the dealio. One thing that is different on my system is
that I did not use the factory hoses. I went with small light stainless braid
teflon hoses.  They are good to 3k psi. The system is tight, tight, tight. If
you went with the factory hoses  it may be acting like a balloon and expanding
a little. Can't remember if you have gauges on your hyd system but that tells
the story of what is happening, not necessarily why though...
 Best,
 Randy.
