"What's the actual name of this part?"
As a Ford parts advisor, this question always cracks me up.
"What is this thing actually called??"
"Well the workshop manual calls it the "SOBDM", but Ford, in their infinite wisdom, calls it "UNIT-CONTROL" in the parts catalog"
Or
"Well I call it a purge valve, but Ford call it "bracket"
Or
"I don't know, it's some kind of oil sensor. The description in the catalog is "sleeve"
