I have the same problem with the 90 degree hydraulic fittings on my SC. They still sell them at the local Case IH store for a whopping $75.00 each.I have tried several different ways to stop them from leaking but have had little success. It appears there is a brass washer inside of them that tends to wear and loosens up the fitting.
The seal in your governor is the source of your other leak and yes it will take a dis-assembly of the governor to fix that. It is annoying to say the least
