i am unsure on what fittings/ tubing to get
i plan to run the loop to a triple radiator in the top and then through the blocks to the radiator at the bottom then back to the pump/radiator. i would also like to put in some kind of drainage system so i can perform maintenance when needed are there any other parts i need to complete my build?
