This appears to be a well-made part and it fit my German-spec 2004 BMW 320i perfectly. It includes the two crush washers for the banjo fitting and the o-ring for the pump fitting. It also had a bracket pre-installed so you don't have to transfer it from the old, leaky hose. Before you ask, I don't know which series of pump I have.Some tips:If you don't have a lift, jack up the right side of the car, even though the pump is on the left. The fluid that runs out of the reservoir and rack will get all over the underbody reinforcement if you jack it up from the left. Jacking on the right gives the reservoir and rack fluid a much straighter path to the drain pan.Also, if you can use a rag and vice grips to pinch the reservoir hose, it will help prevent the reservoir from draining when the hose is disconnected.
