244900 Volvo FH16 D16C Overflow Valve

What does an overflow valve do?

The injector pump overflow valve is a vital control component within the fuel system that regulates internal pump pressure. By redirecting excess fuel back to the return line, it prevents pressure spikes and ensures the injection pump operates within its designed parameters, directly affecting engine stability and fuel economy.
