Power Steering Return/Cooler line

I have a 1993 Olds Cutlass Cierra 3.3L (140,000 miles). There is a power steering line which I believe to be my return line (it goes from the pump, under the engine, makes a long elaborate loop towards the radiator and ends up somewhere near the steering column). This line is very rusty and needs to be fixed. I was wondering if I could cut off the rusted portion of the line and fix it by clamping a hose on where I cut ( I did something similar to the transmission fluid coolant lines). I know I can't do this with the pressure line as the hose would probably burst but was wondering if it was okay to do with the return line and if I am correct that this is in fact the return line.
