Bob, et al
My original dump valve failed in a different way and it left quite a
mess.  Internally there was a small O-ring on the shaft for the handle.
That O-ring was being extruded out of the valve between the shaft and
housing.  It got pretty shredded in the process.  Every time the dump
valve was actuated a drop of hydraulic fluid could be found outside the
housing hanging from the shaft.  Over the span of a year, between
annuals, the back side of my upholstery got soaked with 5606.
Ironically, the high pressure replacement from Lancair had an internal
leak in one direction.  Replacement #2 from a local Parker dealer solved
that problem.
