engine line/hose identification request
 

I've searched the service manuals but I can't find what the hard steel/aluminum line in the picture behind the oil cool adapter is for. my adapter runs is touching this line currently and I'm concerned about about the long term effects of vibration, rubbing etc....

Many thanks.
