My '97 E420 is dripping a small amount of power steering fluid from the area just above the steering rack where it looks like the lines to and from the power steering reservoir come into. Is this the actual power steering pump, or is the pump right where the filler cap is located on top of the engine?

The area where it is leaking has two round pieces right next to each other with reverse torx bolts to remove two caps.

Thanks for any help you can provide.
