1 417 413 006 Injector Pump Overflow Valve for Bosch systems

What does an injector pump overflow valve do?

This injector pump overflow valve plays a vital role in the fuel injection system by regulating internal pressure. By redirecting excess fuel back to the return line once a specific pressure threshold is reached, it ensures the fuel flow to the injectors remains steady and constant for stable engine performance.

Vehicle and system compatibility

This component is engineered for use in heavy commercial vehicle engines and is compatible with Bosch systems. It serves as a reliable solution for maintaining the pressure balance required for efficient fuel delivery during heavy-duty operation.

Installation and maintenance guidance

For professional installation, ensure a clean working environment to prevent contaminants from entering the fuel circuit. It is recommended that an experienced workshop technician performs the replacement to ensure the system is properly bled of air after installation.

Troubleshooting and selection

Failure to maintain the overflow valve can lead to irregular fuel flow or increased consumption. Choosing high-strength components helps prevent disruptions in the pump's internal pressure balance.
