Was going to do a bunch of work but saw hyd. oil on the ground. It was dripping from one of the lines for the stabilizer cylinder so I tightened it a bit but was still leaking. Then I noticed it was leaking from the fitting above onto the lower fitting. Took some covers off and took the steel line off and the flares looked good so put it back on and it was steady stream so I'm thinking there's crack behind the flare. There was a little rust behind the flare too. There's no end to these annoying repairs.
If you're referring to a JIC connection, common for them to crack on the tube flare or the female fitting flare.
