Fuel system (1581): Tightening torques

P3M30HJ01

• Unscrew the two screws (7) retaining the fuel manifold to the inlet manifold
• Take out the injector manifold assembly
• To remove the injectors from the manifold, remove clip (9)
• To remove the pressure regulator from the fuel manifold, unscrew retaining screw (8).

Fuel manifold: Never wash the manifold by submerging in strong fluids. Clean only on the outside using a brush. Otherwise the o--rings may be damaged.

NOTE Lubricate injector and pressure regulator o-rings with pure vaseline (use as little as possible in order not to affect functional areas) before fitting.
