Trying to install my extended brake lines and my worst fear came to be. While trying to undo the hard line connection to the flex line, the nut pulled off the fitting leaving it firmly connected with no way to undo it. Sooo.......what now? Make a new hard line back to the proportioning valve? Cut and reflare the hard line at the flex line connection spot? I can't be the first, so any help appreciated. It's not a left handed fitting is it? The thread in the new one looks right-handed....... Thanks in advance for any words of wisdom.
