Multiple Choice

The valve shut off controlled by the master switch is the ______ shut-off valve.

Explanation:
When the Master switch is off, electrical power to the engine fuel pump is removed. The valve that is wired to that power and will close in that condition is the low pressure shut-off valve. Closing this valve isolates the engine from the fuel line when power is removed, preventing unintended fuel flow and enabling a safe shutdown. The other shut-off valves operate in different parts of the system and are not controlled directly by the Master switch in the same way.
