I’ve read online on how airliners store their fuel in the wings of the plane, and especially how it’s not in a tank, but its just inside the wings.
How exactly does this work? Does this mean the wings have to be completely air tight? If the inside of the wings are mostly structural elements, how do they deliver the fuel while making sure that there aren’t areas in the wing structure where the fuel gets trapped?

I’m a UAS pilot/maintainer. I’ve only worked with wet wings on drones.
Wet wings have fuel cells, these are pretty much bags, inside of them. They are air tight and pressurized. The fuel cells are joined by a line that feeds to the rest of the fuel system.
