I do believe that running at 180 with a long run caused the hose to get too soft to maintain the pressure the rest of the system has. perhaps others are running at a lower temp or have a shorter run? Or my hose was defective (unlikely)?
There is no flexible connection at either end.

Even if the hose blows up like a balloon the pressure should be the same at the other end. This does not make a lot of sense
