Position something suitable under the regulator to collect any components which could drop during the stages which follow.2. Undo the bolts (2a) securing the fuel pressure regulator (2b) to the single fuel manifold pipe.

Never grip the pressure regulator by the electrical connector.

Grip the outer casing of the regulator, partly extract it and, at the same time, turn it so that the fins in which the openings for the fixing bolts are located are positioned horizontally, then insert the blades of two screwdrivers by the fins and very carefully extract the pressure regulator.

Do not use screwdrivers or other tools in the areas between the pressure regulator and single fuel manifold pipe.

Remove the gasket between pressure regulator and single fuel manifold pipe. 1. After removing the regulator, check that the high-pressure seal (1a) (black or green) and anti-extrusion sealing ring (1b) (white) are present. Refitting ( Removing ) Suction off any impurities in the single fuel manifold pipe.Before fitting, check the condition of the two sealing rings and make sure they are correctly positioned.Lubricate the outer surface of the two seals for the pressure regulator using Vaseline.

Do not, under any circumstances, lubricate the other surfaces of the pressure regulator.

Fit a new gasket between pressure regulator and single fuel manifold pipe.Fit the pressure regulator in its seating, pressing gently and at the same time rotating the regulator until it is in contact with the surface of the single fuel manifold pipe.

Do not, under any circumstances, use a hammer or other tools for fitting the pressure regulator in position.m

Tighten to the specified torque the bolts securing the fuel pressure regulator to the single fuel manifold pipe.Connect the electrical connection to the fuel pressure regulator.
