If low pressure is detected in a left engine fuel feed line, which boost pumps activate?

Explanation:
When a left engine fuel feed line drops below the required pressure, the fuel system is designed to act quickly and safely by using both boost pumps. The left boost pump starts to restore pressure on the left feed line right away. At the same time, the right boost pump also comes on to ensure there’s ample pressure available across the whole fuel supply and to keep crossfeed options ready if needed. This redundancy helps prevent fuel starvation to either engine and provides a rapid, reliable way to reestablish a stable fuel supply.
