Hey Eric, not sure about plastic tubing..By the time you put in place all the piping in place throughout the car how much weight you saving? You know I'm all for doing your own thing but having hot water traveling next to you could be a little scary...Not trying to discourage you bro..Also what kinda waterpump does it take to move the water that far through the system?
I'm sure somebody out there has the answers.....Peace out Bro
