Power steering pump leak... from here?

Before I tear the power steering pump apart and find out this can't go together again, has anyone fixed a leak from the power steering pump where the hose flange attaches? Does this flange just unscrew? (Yes, I replaced the o-ring on the hose first and it's not leaking.) Thanks for your advice.

Almost sounds like a micro thin crack in the housing. Guess the high pressure would push the fluid out when the engine is running. Have you tried some stop leak? I say this because it appears you may have to pull the pump, and replace it. That might get you by until you can afford to, or find a way to stop it permanently.

You can remove your line from the pump with a wrench and if there is enough room remove that pressure valve with a Wrench as well and replace the O-ring On the pressure valve and reinstall. You my not have enough room to access which would then require removal of the power steering pump from the Jeep.

Yeah, that's the flow control valve fitting in the pump that the high pressure line fitting screws into. In the below thread you can see it removed with the o-ring on it which likely needs replaced. And note the 4 holes with larger hole in the end for the correct OE one.

Don't get rid of that valve unless there's a major problem with it. A reman pump may not come with the same one if you ever need to replace it. A parts store should be able to match up that o-ring if you take it in and good luck.

That's perfect, thanks. I was hoping there was an o-ring but wasn't sure what would spill out if I unscrewed that. I did take the pump out and I've been replacing all of the o-rings I've found. This would be the last so it's hopefully it. For anyone who would do something like this, I bought an o-ring assortment kit from Harbor Freight and it's been incredibly worth it to avoid driving back and forth to the hardware store. Thanks again.
