20430101 Volvo FH16 D16G Overflow Valve

This injector pump overflow valve is a critical component within the fuel system that maintains the internal pressure balance of the injection pump. By redirecting excess fuel back to the return line, it ensures consistent injection timing and stable engine performance under heavy-duty operating conditions.

This specific part is designed for Volvo FH16 trucks equipped with D16G engines. It serves as a reliable replacement for original components, ensuring that the fuel pressure remains within the necessary tolerances for optimal combustion.

Technicians should verify that the M10x1.5 thread size matches the existing pump assembly during installation. Proper seating of the valve is essential to prevent pressure fluctuations that could lead to erratic idling or increased fuel consumption in heavy commercial vehicle fleets.

Consult your authorized distributor to ensure correct fitment and performance stability.
