    The fuel lines on my Duster run within 2" of the exhaust and headers on the passenger side of the car, putting a lot of heat into the fuel. I was planning on putting some of that foam rubber pipe insulation on it, but I doubt it would live more than a minute or two being that close. I either need to insulate the exhaust or the fuel lines.

    I have a 2" x 100' roll of header wrap that I was planning on using on the headers and part of the exhaust, until I started reading horror stories about it destroying the steel pipes by holding water and rusting them out.

    Seeing as how I already have the wrap, would there be any problems putting header wrap on the aluminum lines? Since they're aluminum, I don't think rusting would be an issue and I wouldn't need to drop any extra coin on insulation.

    I use heat reflecting tape on mine to keep the heat out. I’m not sure if header wrap would work the same. It would definitely insulate, but I think it might hold the heat in (correct me if I’m wrong anyone)….then again with constant fuel flow, it might be fine….I don’t know. Give it a try, see what happens. If it vapor locks try heat reflecting tape.

    I would move the lines. The same shielding that keeps heat out, also holds it in once the line(s) are hot.

    I moved mine as far away as I could and used the thermo heat shield it appears to have helped, I also used one on my brake line. A big block in a early A creates some space issues.
