Why do they use the tubing rather than hard metal pipe anyhow? burn risk? or risk of coolant cooling off in cold outside temps (good thing for engine... maybe bad on the way to the heater, I dont know)? Could I run hard pipe under the bus? I would be running the coolant a max of 8 feet from the driver/defrost heater to the rear. Perhaps only 4 feet depending on which bench seat I put it under.
I really dig the idea of putting it under the bus in hard and/or metal pipe. What exactly could I use???
Rigid lines need flexible couplings anyway, and copper/steel pipes spring leaks from time to time.
They buy the rubber hose by the mile, so it's probably cost-effective.
