1-3-4-2 (Maintenance manual TM9-8012, p. 105, available in the Downloads section)
From your description, I'm guessing "the little pipe thing" is the positive crankcase ventilation (PCV) valve and the control valve for same (if still present). It's called "metering valve" in the documentation, but PCV is a more common term. See p. 113 of the maintenance manual for an illustration.
