What test must be conducted after installing a new spout assembly in the Healy 900 nozzle according to Executive Order VR-201-A?

• A. V/L test
• B. Nozzle bag test
• C. Dispenser leak decay test
• D. Nozzle dispensing shutoff test

Answer: (D)

The nozzle dispensing shutoff test is essential to ensure that the newly installed spout assembly in the Healy 900 nozzle functions correctly in terms of shutting off the flow of fuel. This test verifies that the nozzle can properly sense when the tank is full and can effectively stop the dispensing of fuel to prevent overfilling and potential spillage, which is critical for both environmental safety and compliance with regulatory standards.

Conducting this test after installation ensures that the nozzle's automatic shutoff mechanism is operational and meets the standards set forth in Executive Order VR-201-A. This process is vital for maintaining the effectiveness and reliability of the vapor recovery system, helping to protect against emissions and ensuring safe fueling operations.

Other tests listed, while important in their own right, do not specifically relate to the immediate performance of the nozzle shutoff after a spout assembly installation. This focus on the shutdown mechanism makes the nozzle dispensing shutoff test the correct choice for this context.
