I have loosened the line nut, but cannot remove the hard line from the accumulator. The ferrule is solidly stuck into the fitting. And the ferrule has 'grabbed' the line such that it cannot be withdrawn (although the line will actually rotate within the fitting/ferrule).

I'm considering cutting the hard line, and replacing it with a braided flex line. But I don't see how the flex line is installed. Does it follow the same path as the hard line?
