Where is the 20017 LR3 fuel pressure regulator located and is it vacuum operated? I looked along the fuel rails and did not locate the FPR.

 

From the technical introduction manual

"FUEL PUMP- the submersible electric fuel pump is attached to a carrier and is located at the bottom of the swirl pot inside the fuel tank. The fuel pressure regulator, which controls the fuel pressure in the feed pipe to fuel rail, is located in the fuel manifold in the fuel tank.

FUEL PRESSURE ACCUMULATOR- A fuel pressure accumulator is attached centrally to each of the fuel rails. The accumulators act to dampen pulses from the pump and ensure that the fuel pressure in the rails is constant"
