Instructions
Push the fuel thrusters of your plane as high as they will go. The thrusters will need a lot of force to push fuel through both wings with only one fuel supply.
Turn the "Cross Feed" dial to the "On" position for the wing that is functioning properly. The dial is directly underneath the fuel throttles.
Turn the "Cross Feed" dial to the receiving position ̵2; the white box that has a line running to it from the "On" position of the opposite "Cross Feed" dial ̵2; on the wing that has a broken fuel line. The wing will immediately begin receiving fuel from the opposite wing, which will dramatically reduce the time you can stay in the air but will increase the plane's stability.
