7035096 Volvo FL10 TD103 Overflow Valve

What does an overflow valve do?

The injector pump overflow valve is a critical pressure control component inside the fuel injection pump of heavy-duty commercial vehicles, redirecting excess fuel back to the low-pressure circuit or the fuel tank. By maintaining the injection pump's internal pressure balance, this component ensures that fuel flow remains consistent and prevents irregular delivery that could lead to performance drops.

Vehicle and engine compatibility

This specific component is compatible with Volvo FL10 vehicles equipped with TD103 engines. It is manufactured to meet high-strength standards to ensure durability under demanding operating conditions within the diesel fuel system.

Installation and maintenance

To ensure proper installation, technicians should verify the injection pump type and check for any debris in the return line during replacement. Maintaining the correct pressure threshold is vital for engine idle stability and preventing excessive fuel consumption. Consult your authorized distributor for fitment guidance.

Troubleshooting guidance

If an engine experiences irregular idling or loss of power, inspecting the overflow valve for proper pressure regulation is a recommended troubleshooting step.
