Description

The fuel pump's check valve prevents fuel from flowing back towards the tank, ensuring that system pressure is maintained after the engine is switched off. A properly functioning valve promotes clean starting and a stable fuel supply throughout operation.

Typical symptoms of a worn valve include longer starting times or uneven pressure build-up in the fuel system. This valve replaces the standard component without any modifications and reliably restores factory functionality.
