All, my power steering fluid is completely drained out from the expansion hose running across the front of the engine, the red arrow in the picture below.

it was spraying out when the engine was running!! With noisy pump. I believe I need a new hose system.

But when I checked part number, there are a few. see No. 3 item below.

I tried looking for part number:
32416779316
32416777050
32416774316

but I struggled to find the part, there are different part numbers for E91 from diff websites, can anyone help, which one is the correct one? Anyone changed this before? Is there a more updated part that might look somehow different?

Thanks, the car is left at the driveway with oil all drained.
