93 Suburban 1500 power steering

I have a 93 Suburban 1500,4wd. I was having trouble with the powersteering so I replaced the pump,pulley and both lines. I also flushed the steering box until fresh fluid came out. Now when I start and run the car both steering pump lines heat up to a point where they burn your hand if touched. I am afraid if I I run it I will blow both hoses or the pump. Any thoughts?
