The fittings are what lose their seal, especially if they're 45- or 90-degree bends; if they're not handled properly when attaching them, they can get over-torqued and bent slightly, which ruins the seal within the fitting. The nylon hoses are OK, but just to be sure they didn't rub through any more, I went with steel. No issues at all afterward, but do be careful when installing these hoses and fittings. They are aircraft-quality (mine are, anyway) and the fittings can be damaged if tightened too hard.
