OEM Part
OEM: Made by an Original Equipment Manufacturer. This part is made by an original equipment manufacturer or under their license, ensuring compatibility and quality.
Fuel Pressure Relief Valve is fitted to the high-pressure common-rail fuel system of the 2.4L Duratorq TDCi diesel engine.

Mounted on the fuel rail, it limits maximum rail pressure by opening to return excess fuel to the tank, protecting the injection system from overpressure and stabilising rail pressure during engine operation.

Frequently asked questions

What does the fuel pressure relief valve do?
The fuel pressure relief valve is fitted to the high-pressure common-rail fuel system of the 2.4L Duratorq TDCi diesel. Mounted on the fuel rail, it caps maximum rail pressure by opening to return excess fuel to the tank, protecting the injection system from overpressure.
Which Defender does the LR006866 relief valve fit?
The LR006866 fuel pressure relief valve fits the Land Rover Defender (2007-2016) with the 2.4L Duratorq TDCi 140PS Puma diesel, VIN 7A000001 to BA999999. It's specific to that common-rail engine, so confirm your engine and chassis number before ordering.
What are the symptoms of a faulty fuel pressure relief valve?
A faulty fuel pressure relief valve typically causes hard starting, power loss, or a rail-pressure fault code, and can leak fuel back to the tank so the rail can't build pressure. On the 2.4 TDCi it often drops the engine into limp mode when it fails.
Is fitting the fuel pressure relief valve a DIY job?
Fitting the fuel pressure relief valve means opening the high-pressure common-rail system, so it's usually best left to someone experienced with diesel injection. The system must be depressurised and kept scrupulously clean, as debris in the rail can damage the injectors.
