• Functions:
  
  • Protects fuel system components: By regulating fuel flow, the check valve can help protect sensitive components in the fuel system from damage caused by excessive pressure or backflow.
    
  • Maintains fuel pressure: By preventing backflow, the check valve helps maintain fuel pressure within the fuel injection system. Adequate fuel pressure is essential for proper fuel delivery and engine performance.   
    
  • Prevents backflow: The primary function is to stop fuel from flowing backward when the fuel pump is not actively pumping. This prevents fuel from draining back into the tank, which can lead to difficulties in starting the engine.
