Disclosed is a fuel system with a fuel tank containing hydrocarbon fuel, a hydrocarbon fuel flow path in fluid communication with the fuel tank, and a gas separation pump disposed on the flow path. The gas separation pump has a pump housing with an inner wall defining a cylindrical internal cavity. The pump housing includes an inlet at a first axial position along the cylindrical cavity outer circumference, an outlet at a second axial position along the cylindrical cavity outer circumference, and a vacuum connection in fluid communication with the cylindrical cavity axis. A first impeller with an outer edge configured to sweep along the inner wall is axially disposed between the inlet and the outlet. A second impeller configured to eject liquid through the fluid outlet is axially disposed between the first impeller and the outlet.
