If it were mine, I would unscrew the Banjo bolt that holds the swivel to the oil pan. That bolt should be a straight (not pipe ) thread, probably the same as the oil pan plug. Take the hose and the bolt to a hydraulics shop. Tell them you want a fitting to screw (and seal) in the hole where the bolt came out, turn 90 degrees, and become 1/2" id hose or have 1/2" hose barb. They should be able to hook you up.
Btw, you want a good quality hose, but it doesn't need to be 3,000 psi rated hydraulic hose.
Anyway, that's what I would do. Your milage may vary; past performance doesn't guarantee future results; I can only be held liable to the amount of the fee you prepaid for this opinion.
I'm tired of fast moves, I've got a slow groove, on my mind.....
