0104 042 Volvo Compatible Injector Pump Overflow Valve

What does an injector pump overflow valve do?

The injector pump overflow valve is a critical pressure control component that redirects excess fuel back to the low-pressure circuit to maintain internal pump balance. By regulating the recirculated volume at a specific pressure threshold, this component prevents irregular fuel flow and ensures stable engine operation under heavy-duty conditions.

Compatible Volvo engines and vehicles

This overflow valve is specifically engineered for various Volvo engine models such as the F10 (TD102), F12 (TD122), FL10 (TD103), FL12 (TD123), NL10 (D10A), NL12 (D12A), B10B (D10A), B10M (D10A), and B12 (D12A). It also serves as a reliable solution for other heavy commercial vehicle applications, including those from MAN, Mercedes-Benz, and Scania.

Installation and maintenance guidance

For workshop technicians, maintaining the fuel system requires precise selection. When replacing this component, it is vital to verify the pump type and opening pressure settings to ensure compatibility with the existing injection pump assembly. Proper installation prevents issues like increased fuel consumption or erratic engine idling caused by pressure imbalances.
