Sorry, but this is one case where I would definitely go with Sean's advice. The point of the anti-siphon tube, is to make the valve draw from the part of the tank where the liquid CO2 isn't sitting, namely, the top most part of the tank. When the tank is on the gun, that would be whichever side of it faces up. Since the anti-siphon tube reaches to near the middle of the tank's length, if you tilt the tank, the pickup will no longer be at the topmost point, and will be much more likely to draw liquid CO2. If you understand how an anti-siphon tank works, its just common sense that the wedge is counter-productive on anti-siphon systems.
