Question regarding AC/Heater removal

[kehstr]

you could plug the lines, but it will let more coolant circulate, if you just connect the two points, along with the lines, there is no upper water pump line, do you have any overheating issues?
I second getting rid of the rubber fuel lines and replacing them with steel, the rubber lines like to leak, and then start fires. Where you have to have rubber lines, make sure you use fuel injection line, that is specifically make to hold to the chemicals in Fuel.
