1969 Plymouth Satellite gas tank question

Murray said
This is a vapor recovery system, new in 1969. As to where all the hoses routed, or which ones can be plugged, others will need to help.

Are you certain? evap controls were introduced in CA in 70 so far as I knew. The factory book shows at least two vent lines. Neither is tied to the front of the car, or a "carbon can."
