Another gotcha is that some flex hoses come through with thinner copper washers than original - noticeably thinner. I had a small persistent leak after a replacement, and had to go out and buy another set of copper washers from the Help! section of Autozone, which were the same thickness as the original. So compare the new washers to the old before installation. I want to say the old were something like .070 inches thick even after crush/use, and the new ones supplied with the hose were something like .032 inches.
