No worries, happy to help.

Just want to add how I came upon that info. I checked my car and found the lower hose going to the head. Then looked it up on www.realm.com and gave you the part number listed for what is seen as the lower hose in their diagram. It is also listed as the inlet.

I write this because I recently replaced a rigid fuel line and looked it up on realoem based on it's outboard position. The part that BMW sent looked more like my inboard line (shorter).

I took the hose from the old M30B25 engine and it had a different number on it what I couldn't find in Realoem. I also didn't know anymore which line was connected to which port. The car did have an engine in it for about a year .

Anyway it's ordered.
