Wrong. Everybody knows that a higher fuel level inside the float chamber means HIGHER CONSUMPTION. Furthermore, the fuel level is NOT decreasing 'as fuel is used' since the fuel pump is constantly filling the chamber at a greater rate, regardless of engine load.
Y are you thinking the fuel level will rise? The fuel bowl is not sealed off with the vacuum tube connected to it. If it was sealed off, the device connection would draw liquid through it and into the intake. That is not what this setup is supposed to do. If someone has their setup with that much vacuum, the engine would flood. The device is designed to draw or purge the vapors from the fuel in the bowl. The air vent allows the air to purge the vapors. Instead of arguing about it, wouldn't it be easier for you to ignore the device and try another? In reality, these devices tweak and fine tune fuel systems. Not all vehicles will obtain the same results.

I'm not sure about your vehicle, but mine reduce fuel flow to the carb when the fuel bowl level increases. You must have a bad needle valve if your level continues to fill.
