charcoal cannister

[NM Bronco]

How do you tell which port is " vacumn" and the other is air inlet on top of the cannister? Also, could you attach the " vacumn" side to a real vacumn like the PVC line or maybe to a vacumn outlet from the carb or intake? thanks

can you run directly from the gas tank vent to the CC?

Only if you run the late model (76-77) can, which mounts high up on the fire wall. If you mount it down on the frame, expansion in the tanks can result in fuel getting into the can instead of just vapor, which pretty much ruins the whole show. That is why that little plastic bottle is behind the driver's seat under the panel on pre-76 models since those had the can mounted on the frame instead of the firewall. The plastic thing is a liquid-vapor separator.

If your Bronco is before '73 or so, you won't have that bowl vent, so no worries if you don't see one on your carb.

Thanks...I was also kinda curious why I didn't have an evap bottle. This cleared it up.
