1. Locate the injector lines. The injector lines are the metal lines that run from the fuel injection pump to the injectors.
2. Loosen the injector lines. Use a wrench to break loose the banjo bolts that connect the injector lines to the injectors. Be careful not to loosen them too much, as you do not want to damage the threads.
3. Allow the air to escape. Once the injector lines are loosened, allow the air to escape from the lines. You will hear a hissing sound as the air escapes.
4. Tighten the injector lines. Once the air has escaped, tighten the injector lines. Be sure to tighten them snugly, but do not overtighten them.
5. Start the engine. Start the engine and let it run for a few minutes. This will help to circulate the fuel through the injector lines and remove any remaining air bubbles.
6. Check for leaks. Check the injector lines for leaks. If you see any leaks, tighten the banjo bolts until the leaks stop.
