Well, maybe I'm not calling the parts by their correct name, but on this Bubba car, coming out of the radiator top tank are two short radiator hoses, one going to each bank of cylinders and two water pumps. Then a steel tube approximately 14" long and than another short hose to the water inlets or outlets. But, not a solid rubber hose run. I have the same set up on my 42 WWII jeep that was explained to me as due to the rubber shortage, they used a steel tube where possible. But my Model T's also have a brass tube in the cooling line and it was explained to me that on the T's it was to aid in cooling. Either way, I got steel tubes on my car.
