Good thoughts there Rich, but what I don't get is that it isn't very brittle. In fact, it is soft. The original end WAS brittle, but the rest is soft. It just split because(I'm assuming and I know what they say about that) because the end wasn't as big as it needed to be when I put the un-split end on? Is the line supposed to be big enough on the end to stick on the fitting on the manifold(?) and then shrink down really small? Where would I get a hose anyway? Napa?
