Mike,
It's the hose from the DINSE connector (hot water from torch) that is too short. The one coming from the jacket is the cold water supply to the torch and that is no problem. It looks like the specified length of the hose on the DINSE was about 8 inches too short for a good relax fit to the cooler.

gezer,
That is the first thing I thought. Both chains are the same length. All it would take to correct is to specify one chain being three links longer than the other. This would require the same amount of chain.
