To get air out of fuel lines, first ensure the vehicle is parked on a level surface. Turn the ignition key to the 'on' position without starting the engine. This activates the fuel pump. Locate the bleeder valve on the fuel rail, place a cloth over it, and depress the valve to release air. Repeat this process until fuel, rather than air, is expelled. Safety is crucial; avoid open flames and work in a well-ventilated area.
