      Comments about Design Engineering Cool Tube Extreme Blue 3/4" dia. X 3':

      I bought this to wrap around my fuel injectors on my Jeep's 4.0, as I was having heat soak restarting issues. I still do. Perhaps if I had removed the fuel rail and slipped the tube over instead of slitting it and crimping the tube over them it would've worked better. I still have plenty of leftover to try this, but not the time right now to try it.
      I do like the color choices and multiple diameter choices though and still want to give this heat tube a chance before making my final judgement, therefore I will recommend it for now.
