AH, help, I'm confused.

You are not confused, you are just not thinking as to what actually has to happen for the ANTI-siphon to work correctly.

A correctly installed ANTI-siphon tube has to be installed with a curve upward towards the gas only bubble in the top of the tank. This assures that MOST of the time a gulp of liquid CO2 does not make it into the marker.

The ANTI-siphon has to be fitted to the correct tank and gun orientation. The tank is screwed into the ASA on the marker and the high side (in the shooting position) of the tank and valve are marked. The valve is removed, the ANTI-siphon tube installed and bent slightly to curve up-wards to the high side of the valve. The valve is re-installed and when it is tightened into position, the marks again align assuring that the ANTI-siphon tube's open end is sticking up into the gas bubble of the tank.

Each CO2 tank has to be treated the same way to assure proper position of the end of the ANTI-siphon tube.
