Blew power steering return hose

Hmmmmm that's a toughy.
I might bet that you got a Federal pump, which I would asap remove and drive over it with an asphalt packer. You know, I studied that Federal, and it looks like a great design, but I just never had any luck with those.
Got me a Saginaw, and that was the end of my troubles.
I'll guess your relief valve stuck.
