The present disclosure relates generally to a system for inerting a fuel tank. The system includes a fuel pump, a jet ejector, a first flow path between the fuel pump and the jet ejector, a valve along the first flow path, the valve blocking the fuel flow from the fuel pump to the jet ejector when closed, a second flow path from the ullage of the fuel tank to the jet ejector to allow fuel vapor from the ullage to travel from the ullage to the jet ejector, a vaporizer downstream of the jet ejector and configured to vaporize the fuel received from the jet ejector into the fuel vapor, and a third flow path along which the fuel vapor flows from the vaporizer to the ullage so that an fuel-air ratio in the ullage of the fuel tank is maintained at greater than a flammable fuel-air ratio.
