Help! My steering quit! (PROBLEM SOLVED)

I replaced it because it was 47 years old, and original to the car. I'm planning on taking the car on a long road trip and didn't want to blow a steering hose in the middle of nowhere. I keep thinking about what happened to those guys in the movie "Deliverance". Anyhow, the pump worked perfectly until I replaced the pressure line a week later. That's when it stopped working at idle. But it was working perfectly after I initially changed the return hose.
