Good idea and I thought of that as I was perusing through some of the hydraulic fittings. It's very small it 1/8" OD, so not sure that a standard whip wouldn't work. There is vibration, of course, but I don't think that'd be an issue (?).
Yep, I'd love to know where it was found for the connections too. It's a very simple connection as the O-Ring is the actual seal as it butts up to the interior of the adapter fitting on the block. The threads on the straight-side just put enough pressure on the O-Ring for that seal. Obviously, it can be reused over and over, many times by replacing the O-Ring only.
As always, thanks to everyone for their suggestions and ideas in my odyssey.
