Power Steering Pump Supply Hose, Rein - E39 M5

This part is listed by BMW as BMW part number 32412228873 and is described as Power Steering Hose - E39 M5 - 32412228873 - Rein.

This hose supplies the power steering pump with fluid from the reservoir. BMW calls it an "intake manifold" or "suction pipe". The hose can also swell over time, causing a leak, and the hose must be replaced. A crimped hose clamp was originally used but this can expand and cause an PS fluid leak as well. We recommend a 18-24mm premium hose clamp instead.
