Yes, I learned another lesson with this episode...

   Lesson One is to check the hoses used in my brake bleeding
equipment...it seems that brake fluid does a job on most of the tubing that
comes with these 'tools'

   The reason I pumped that much pressure into my system is that it was
losing pressure quickly... and I was working alone...so by the time I could
get out of the van and crawl under to check for leakage, the pressure
bottle was losing all pressure at a lower PSI....I should have found a
helper to keep pumping the pressure bottle but I'm quite rural and my S.O.
was not around...

   The Motive pressure bleeding system has a 'feed hose' inside the
reservoir so that it fills the vehicle's brake reservoir through the hose
to a cap that you screw on in place of the standard reservoir cap...This is
to prevent running  dry of fluid during the bleeding process and forcing
air throughout the system...When finished with the pressure bleeding
process, you must carefully unscrew the Motive cap (because the vehicle
reservoir is brim-full of fluid) and use a turkey baster or some suction
device to lower the level in the reservoir to the marked "Max" level...
   When that  hose between the Motive pressure bottle and the vehicle
reservoir let loose....it became, in essence, a weed-sprayer, but with
brake fluid....and I had just put a large bottle of fluid into the
Motive...that blew all over the inside of the van and everything in
it...Not at all pretty/

You pumped a brake pressure bleeder up to 20 psi? So what part of the
reservoir and connecting system was designed for pressure? Watching the
reservoir tank swell at 2 or 3 psi tells me to stop. This should not be
necessary to do the job. Things on the pressure side operate at much higher
pressures so this is not even a good method for lea testing.
