It is important to be intact because warm air will enter the refer and raise the temps more that you would imagine. In one friends setup I was able to slide a clear plastic tube inside the old tube. Enough of it was intact to hold well. In some setups there should be a U so the end is higher up so it can trap a bit of water to act as an air plug.
If the set up is not designed with a U, what keeps the warm air from getting in? This hose is already pretty short just to make its exit point. If there's suppose to be a U I would have to get really creative.
