Power Steering leak?

I replaced my pump. Install went smoothly. A few days later, it seems to be dripping from the line to the pump where it goes into the pump. I am referring to the line that goes to the pump that you need a semi-big wrench for (18mm or 19mm), not sure what size it is.

I believe I tightened it to death. Then, drove 45miles to another fanatics place to meet up with him. He says I just made a line of fluid about 10feet long. I see the line got loose. Luckily he had an adjustable wrench. So I tightened it, topped off the fluid and went on with my day. Now, seems to have gotten slightly loose. There are drops coming down from the lower line.

Is there supposed to be an o-ring, maybe a crush washer that goes on the line before it screws to the pump?

Make sure not to over tighten. Can cause stripped bolts

Yes, there's supposed to be an o-ring where the high pressure line bolts to the pump. You can probably pick one up at your local dealer's parts counter for a buck or two. Hopefully that's the only problem, and the line itself isn't messed up.

I seem to have developed a leak at the bottom of my power steering pump where the line goes in to the pump. But I'm not 100% sure that is the location of the leak.

OP, did you replace the O-ring that is in there? Was there an O-ring to replace?

Did that solve the problem?

My car has 117k miles and has recently developed this leak. I'm hoping that it's a simple fix.

TIA

They have an "A/C O-ring Set," which contains tons of various-sized o-rings. It's really cheap and more than likely contains the right one in it. I found the right one for an obscure o-ring I needed for my washer pump.

Part # for O-ring -

Is #4 the O-ring on the fitting that attaches to the bottom of the PS pump?

If so it's part number: 64508390601
