To clear a diesel airlock, first, locate the bleed screw on the fuel system. Loosen this screw and manually pump the fuel lift pump or use the priming handle until fuel flows free of air bubbles. Tighten the screw once the fuel is bubble-free. Restart the engine to ensure it runs smoothly. Repeat the process if necessary. Ensure you have enough fuel and all connections are airtight to prevent future airlocks.
