Abstract: In some examples, a system configured to remove at least some air and other gases that are dissolved in fuel prior to introducing the fuel into a closed fuel system, such as a closed fuel system of an unmanned aerial vehicle. The system includes a vacuum chamber configured to contain a fuel, a vacuum source attached lo the vacuum chamber and configured to draw a vacuum on a headspace over the fuel in the vacuum chamber, and a fuel pump configured to pump the fuel from the vacuum chamber into a closed fuel container without introducing air into the closed fuel container. In some examples, the pump introduces a fuel substantially free of dissolved gases into the closed fuel system.
