I ran into the same problem... I needed a quick disconnect for my MD-6XP as well. I was fortunate to have a shop that was close by my home that made this particular hose assembly in less than 5 minutes!
It consists of an 18" "whip" section that attaches to one of the hydraulic rams. (I switched mine from the default left hand side to the right side to better suit my application.) I made the other section to be 12' for my application. Approximate cost for the entire assembly was around $130, including assembly, hose, fittings, and quick disconnects.
When not in use, the "whip" section is conveniently stored to the side, held to the side of the ramp by a magnet.
A close-up of the connection to the hydraulic ram:
Here's a close up of the neodymium magnet used to hold the male connector to the side of the ramp. The magnet was from a 3.5" hard drive I no longer needed

Unfortunately, it cracked from one too many "attachments"
Male - female counterparts:
Here's a picture of the female disconnect. It shows a tiny amount of ATF fluid after removal. This is one of the downsides of this system. You lose a tiny (negligible, IMO) amount of hydraulic/ATF with each disconnect.
A close up of the male connector:
An improvised cap for the female connector to capture the small amount of ATF and to keep dirt out when not in use. I'll figure out a better method sooner or later, but for now, it seems to work.
The type of hydraulic hose I got for the assembly. It's 100% more pliable than the original one from Bendpak. It made THAT much more noticeable difference when moving the hose for storage.
Hope this helps,
Mike
