I know this is an old thread that has been revived at least once before. Here is my two cents. I had a '54 Jeep and we changed out the engine. I ignored those funny looking braided things when I put it back together, thinking that the factory engineers were always adding worthless clutter. I was wrong. I could not figure out why the vehicle would start just fine and run strong and then after a few minutes always die. Sent it to my ace mechanic former Amoco station owner who knew a lot. He said the gas line got really hot and boiled the gas in the line. The gas line got hot because it was acting as the ground wire because my ground straps were missing. Once the straps were reinstalled the engine quit dying.
