I had some front end work done about a year ago and in the process of replacing the steering box they replaced the power steering hoses. So I can’t remember if it was doing it when I first got it back but I know for the last 6 months or so I’ve been leaking power steering fluid after the car sits for a few days. I’m not 100% sure where it is coming for I just know the bottom of the reservoir is wet with fluid. I guess my questions are is there a rubber seal that could be missing of the back of the reservoir where the hose connects? Or is there another place where fluid could drip from?
 
There is a seal on the input shaft, an o-ring around the pump body that seals to the reservoir, a rubber gasket (I think it's rubber) between the fluid supply fitting and reservoir, the flare fitting to hose at the supply, and the hose clamp fitting at the return.

Check the housing for any dents....it used to be common for inexperienced mechanics to pry against the reservoir when tightening the PS belt. If it's the front seal, you should be able to see a fluid trail from the seal going downward.

The gasket between the reservoir and the inside surface used to be rubber and steel. The new replacement in the kits is just a paper piece of garbage which is almost guaranteed to leak. Use "The Right Stuff" on clean surfaces and good to go.
If it's leaking from there, it's a tare down job.
