Here's latest update:
Got the fluid, topped off motor/pump, cycled power to it off and on, reversing a couple of times, got it to push fluid into the system, confirmed location of leak. It's not the lines as suspected, it's the RH actuator. Must've blown a seal and leaks this stuff right out from it's housing.
Since it's a replaceable part, I'll give it a shot (thankfully with a little help from
THIS).
Also, depending on turn around time, may consider a rebuild pair from
these guys. Two for the price of one. Anybody have any experience with them?
