Removal
Caution: There is a high risk of burns due to the fuel system being under high pressure. Before performing any operations, it is necessary to relieve excess fuel pressure in the system.
1. Remove the intake manifold assembly (for more details, see the relevant section in the chapter "Intake and exhaust system").
2. Disconnect the high pressure fuel lines.
3. Disconnect the wiring harness connector (1) shown in the figure below.
Note: Wrap the connection point of the tube with a clean rag to collect any leaking fuel.
4. Unscrew the mounting bolts (arrows) and disconnect the fuel distributor from the fuel injectors as an assembly, as shown in the figure below.
