Overheating 360 new engine

Does anyone have a lower hose part number for the hose with the spring? Once I took mine off I realized I don’t have the spring.

You can take a 3' long x 1/16" stainless steel bare welding rod, wrap it around 1 1/2" PVC tube and make your own inner radiator hose spring to keep it from collapsing from the suction of the water pump.
