    Got HAC?

    '79-newer 2F has a Hi Altitude Compensator valve that will open at higher altitudes, thereby bleeding air into the emulsion tubes of the carb. More air=more lean. The system is supposed to allow the vehicle to run from sea-level to the mountains with normal drivability and emissions. Check the emissions FSM for more info.
