2. Loosen the bleed screw on the top of the fuel filter. This will allow the air to escape from the lines.
3. Have someone crank the engine for a few seconds while you watch the bleed screw. If fuel comes out of the bleed screw, then the lines are full and you can tighten the bleed screw.
4. Start the engine and let it run for a few minutes. This will help purge any remaining air from the lines.
