Just recently purchased this vehicle last Sunday

Just recently purchased this vehicle last Sunday. Diagnosed an issue which is the power steering. I knew/was told the power steering was having problems didn't know how bad till I had it on the pavement when I got it to the destination. I poured some in the reservoir started up the vehicle cranked the wheel left and right for a minute and then shut the car off and saw only the fluid dripping right above the flex pipe of the muffler. I'm wondering if anyone has had experience with this if it is either the rack and pinion or pressure line. Any input to these two discrepancies would be great since my two uncles of back yard mechanics don't have the "time" to help i'd like to get these done as soon as possible to have something on the road. And what is the difficulty of this repair scale 1-10
