Fuel Pressure Regulator for the multi-point electronic fuel injection system on the 3.9L V8 EFI petrol engine.

Mounted on the injector fuel rail, it holds a constant pressure differential between the rail and the intake manifold by referencing manifold vacuum, bleeding excess fuel back to the tank through the return line. This keeps injector delivery consistent across changes in engine load and throttle position.

Frequently asked questions

What does the fuel pressure regulator do on the V8?
The fuel pressure regulator holds a constant pressure difference between the injector fuel rail and the intake manifold on the 3.9L V8 EFI petrol Discovery 1. It references manifold vacuum and bleeds excess fuel back to the tank, keeping injector delivery steady across engine load.
Where is the fuel pressure regulator fitted?
The fuel pressure regulator mounts on the injector fuel rail and connects to a manifold vacuum hose. It sits in the fuel system on the 3.9L V8 EFI petrol engine, controlling rail pressure at the point the injectors draw from.
What are the symptoms of a failing fuel pressure regulator?
A failing fuel pressure regulator typically causes rough idle, poor starting, black smoke or a fuel smell on the V8, as rail pressure drifts from spec. A split diaphragm can pull raw fuel through the vacuum hose, which usually shows as heavy over-fuelling.
How do I confirm this fuel pressure regulator fits my Discovery 1?
This fuel pressure regulator fits the Discovery 1 (1989-1998) with the 3.9L V8 EFI petrol engine from VIN MA081992. Check your VIN against that break before ordering, as earlier engines use a different regulator.
