I've had an experience with a waterpump that I replaced and the impeller was plastic and the pump casing was metal. Under load the impeller slipped on the spline. At normal running loads it didn't slip and the temperatures were normal. I would never buy a water pump with a plastic impeller again.

Best guess is the bent hydraulic pipe has a stress crack in it either under the fitting or or at the swedged end. Not uncommon after many cycles. I would replace the hydraulic formed line
