If you look closely at the first picture you can see the machined slots.

I imagined it had to work that way, but I am wondering how full does the air trap need to be?
Usually air traps are effective down to about 50% or so of fuel content, while in this one it seems to me that as soon as the fuel level goes below the top of the inner tube (about 75%?), the risk of an air bubble getting stuck in the inner tube and potentially getting sucked into the engine becomes very relevant, is it so?

Thanks
