The Fuel Prime Pumps are used during which operation?

Explanation:
Priming the fuel system ensures fuel is in the lines and ready for ignition. The fuel prime pumps push fuel into the engine’s fuel lines so the engine can start smoothly, especially after shutdowns or when fuel may have drained back. Once the engine is running and the main fuel pumps take over, priming isn’t needed. So these pumps are used during engine start.
