Most generally, your lower (suction hose) should have s "spring" in it. I have never heard of top hose collapsing, but if the spring works to keep it from collapsing then run a spring in both hoses. If you are not having overheating issues from there, I would not spend much time worrying about it. Once the engine starts building heat, your cooling system should pressurized. If you don't have a working temp gauge, I would definitely install one.
Do the Stude engines have a t-stat bypass, like all other makes? I would assume they would have to, otherwise all Studes would have collapsed hose issues until the t-stat opened. Is the bypass plugged, or blocked off?
