So, I have spotted this leak under the banjo bolt on top of the power steering pump. I checked the fluid a it was just a hair lower than min, so I added a little to be safe. I just bought the car recently, so I don't know when the leak started.





I have read many threads on power steering leaks, but they all discuss how to change the entire hose or rack. I believe my leak is only from the banjo bolt or a washer that must be there. Am I correct? In other words, is it possible to simply unbolt the banjo bolt and replace it and a washer?
Is this the bolt I'd need? 8E0422529
Is there a specific washer that is below the banjo bolt? There seems to be another nut below the actual hose connection and the leak seems to come from under that.

Thanks!
