000 074 05 15 Injector Pump Overflow Valve for Mercedes-Benz

What does an injector pump overflow valve do?

The injector pump overflow valve is a critical control component that maintains internal pump pressure by redirecting excess fuel back to the return line. By regulating the recirculated volume at a set pressure threshold, this component ensures that the injection pump provides a steady and consistent flow to the engine injectors, which is vital for combustion stability.
