How do you get air out of fuel lines after replacing a filter in 2003 jetta tdi?

1. Turn the ignition to the "ON" position, but do not start the engine. This will turn on the fuel pump and help bleed the air out of the lines.

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.
