2000 E39 528i Replacing High Pressure Power Steering Hose and small O ring fell out?

When removing the High Pressure Power Steering Hose at the fitting on Power Steering pump a small O ring fell out. I think it goes on the end of the fitting as I show it in the pictures? Is this the correct position? If not where does it go? It definitely came from the inside the pump and fitting. Also what's the torque spec's for the fitting and banjo bolt?

Thanks

Yes, that's where the O-ring goes. And it's a good idea to replace it with a new one. BMW p/n 64508390601, diameter 7.65mm.

P. S. If you decide to reuse the old O-ring (which I don't recommend), install it in the same position it was originally. Which would be the opposite of what you have in the 3rd picture.

So that the information is easier to find in a single thread, I added this information to the thread below:
