The #2 in that picture is the high pressure side (liquid refrigerant) line, You should only charge the system on the low pressure (suction) side of the system, which is the #1 in your picture. If you're going to use one of those cheapo single blue hose auto-parts store set-ups that's attached to the can then the blue hose on the 134a refrigerant can will only connect to the correct low pressure fitting, it won't connect to the high pressure fitting because they're different sizes.
