8122353 Deutz Compatible Injector Pump Overflow Valve

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 pump pressure. By redirecting excess fuel back to the return line once a specific pressure threshold is reached, it maintains a constant pressure balance within the pump, which is essential for stable engine operation.
