Help changing \ installing power steering pump.
It may sound simple to most but I have just started doing my own work and the first task on my list is to change the power steering pump. I have gotten as far as getting the old one out, the pulley removed and finally brackets and pulley installed on the new pump. This is where I need some guidance. The new pump came with the little half moon for the pulley (which I used) and two O rings, a smaller and a larger one. Neither O ring fit anywhere that makes sense and looking at the old pump, I don't see any O rings in the pump or on the pressure hose. The larger of the two I thought might go into the pressure side hole before the pressure hose but I am not sure that's right not to mention it does not fit.
Can anyone advise me on where these O rings might need to go, if anywhere?
Just for reference the pump was not leaking at either hose, it was leaking badly from the front bottom.
