How do you remove air from the fuel system?

To remove air from the fuel system, start by locating the fuel bleeder valve, usually found on the fuel rail or filter. Use a wrench to open the valve slightly while pressing the fuel pump or turning the ignition to the "on" position to allow fuel to flow and push out the air. Once fuel flows steadily without bubbles, close the valve. Finally, check for leaks and ensure the engine starts smoothly.
