Blew power steering return hose

Something had to have plugged it. There should be NOTHING to build pressure between hose and pump. Either that or it got kinked somehow. I'd also suspect the hose is rotten/ liner collapsed

That is why I'm so confused. Hose was new. Not kinked. Nothing plugging the return to the pump.

The pump has been leaking from the cap when the fluid is foaming. Excessive pressure from the foaming?
