There's actually hot, high pressure GAS on the outlet of the compressor high-side, not liquid. The liquid doesn't form until after the condensor does it's job - hence its name. That's why I would draw the high side gas from the donor and bleed it into the low side of the recepient...I wasn't planning on just opening the valves full blast, but regulating the pressure to maybe 60 PSI on the outlet of the donor car...that would be enough to go from high to low.
