Can't Find Part Number To Identify

[ROB_D]

Hi all, I have searched everywhere but can not locate this part number. it is a breather tube I guess but have no Idea where it connects to.
Anyone Know?

F6ZE-9F764-AA

That is a Ford engineering number. If the fourth character is anything but a Z, its an engineering number. Call any Ford dealership and they can convert that number to the current correct part number.
