3. Tighten the main fuel supply line (5) which connects to the main connector assembly to a torque of 26 N·m (19 lb ft).

4. Tighten the pilot fuel supply line (4) which connects to the pilot connector assembly to a torque of 43 N·m (32 lb ft).

5. Start the engine, and run the engine in order to ensure that there is no fuel leakage after service work is performed.
