Power Steering Pump connections

Hey guys -- take a look at my power steering pump - I have one connection that I think is the high pressure and the other is a return maybe...

I can probably find a fitting for the the one with threads but there is one without threads ( it has an oring where the stock reservoir would fit. How would I make a connection for the line to the BMW reservoir. From What I can tell I will have one going to the ACtuator for the hydroboost system and the other to the reservoir ( see picture attached - thanks to Pete)

That fitting area with the O ring is a press in tension fit setup. Normally it would have a tank bolted down on it. I'm not sure why you wouldn't use the factory tank, but If you are not using it, then you will have to have a custom fitting made and figure some way to secure it to the pump. As a last ditch effort you may be able to tap threads into that hole. I have never tried it but any thing is possible.

Umm -- thats crazy I wanted to change the reservoir as I was told that the stock one would be to small with the BMW system -- The BMW hydroboost is larger and will hold more fluid

What I think I will do with this is get a brass fitting and press it in with green locktite -- And put a regular return line hose on it

I tapped that input port using a bottom tap and added a an AN adapter. There's a pic of the completed pump hose setup here:

I saw that pic -- I thought it came like that -- I went to get a tap last night --did not find one that diameter.

Ill go to harbor freight tonight to get one

There was another solution to press a pipe fitting into the inlet of the pump.

I tried to to the press in fitting, but my Turn One pump has a larger input than my stock one, so nothing off the shelf fit. If you are going to tap this like I did, you will need to have a bottom tap, or make one like I did. I tapped what I could first, then I cut a few threads off the tap and tapped again to get further down. I kept repeating this until the tap almost reached the bottom of the port. The alternative is to buy an expensive (about 50 bucks) bottom tap. In my case the HF 3 piece pipe thread tap set worked great ($15), I cut down the 1/2NPT tap. Cutting the tap was easy with my 3.5" cut off wheel.

If you have a stock pump, you should be able to press the copper fitting in which Rich mentioned, which is quite a bit easier to do.
