Default 06 2.4 auto:Power steering pump leaks at screw (not Orig)

Hi,
Searched but did not find answer. Shop said power steering pump is leakng at o-ring and screw. Looking at youtube, O-ring must be high pressure line. I have no idea about the set screw:
1. Am I better off getting a new pump at this point?
2. What is this screw for?
3. Can it be safely removed? Like are there springs or other things behind it? Does it need an o-ring?
4. Is it a critical adjustment that the shop can't readjust to a spec?

They are considering pulling the screw out and teflon taping or lock tight to seal. Any thoughts on that approach?

Thanks for your help!!

I assume they're talking about the #25 screws holding the flange for the high-pressure hose. The screw isn't the leak. The O-ring #20 is what they should replace.

If they're talking about some other screw on the PS pump body, then I don't know which screw they're talking about...

Thanks. Pretty sure it is not the flange fastener. Apparently there is a screw on the pump body itself. That is all I could undesrtand. It was referred to as a set screw. Hmm, any other ideas?

Here's a parts picture for the pump. I really don't know which screw they're talking about. But you'll see that they each have an O-ring or other kind of gasket. PTFE tape around the screw is kinda ghetto, and probably won't work as well as just replacing the proper seal.

Very cool diagram. I would like to find a larger or higher resolution one to show the shop. I agree replacing the o-ring makes more sense if they can get that part. I am debating having them replace the whole pump. If has 160k miles on it. I was told by the same shop power steering pupms and those HP line orings are common failure points. The replace cost if $450, and o-rings cost is $275. Seems for $174 I should just do it and notrisk a leak later on I just have to repair. Thoughts?

There's a lot of on-line parts places that use the pictures from Honda's electronic parts catalog.
(Rock Auto, Majestic Honda, etc...) I haven't seen higher-resolution around.

WOW, I've replaced both the high pressure line and all of the return line pieces for about 200 bucks (me doing the labor) on my 99 Accord 4cylinder. I got the pressure line thru Rock Auto for 67 bucks, and it came with a new O ring. The return line I got most of it thru e-bay, using genuine Honda lines and hoses.I did have to buy 1 piece of line ("U" shaped hose) thru cheap Honda parts .com (it was a Honda dealer part).
