I was about to go to the store till I saw all my ps fluid leaked out, I checked it and it looks like a yellow gasket was broke but not sure, from the bottom looks like it's coming from the hose or it might just be dripping on it

 

That gasket is known to eventually blow out. You can either tear it down and replace the gasket or just get a refurb PS pump.

 

I replaced the pump and the lines recently on mine, it's not fun but it doable. The more stuff you take off the easier it gets.
