I have been looking for a replacement for a 2003 M45 power steering return pipe. Everywhere I look it says this part has been discontinued. I can't seem to find it on eBay either. Does anyone have any suggestions?

The link to the part description is below.

It's been a while since I was under a Y34, but I feel like you could make a similar line out of store-bought tube that you bend to your liking...and if needs a fastener, you could flare it.

Or, you could do what people do with brake lines, and get a flex line zip tied to keep it out of rotating components in the engine bay.

Also, if getting a used one is an option (it looks like it's just metal), I know there is a Facebook group where people usually share their partouts.
