Attention. When connecting and disconnecting the pressure gauge, use a rag to protect the engine from possible splashing of fuel.
Remove the engine junction box (BSM).
Relieve pressure in the supply system:
- remove the fuse F5 from the motor switch box (in the zone «A»);
- start the engine and leave it running for a few seconds (to remove fuel from the power system).
Disconnect fitting (in the zone «b») (common ramp (2) fuel injection systems).
Connect a measuring device to the fuel supply pipe (1) and to the high pressure fuel rail (2).
Reinstall fuse F5 of the motor switch box.
Start the engine.
Measure the pressure.
Working pressure: 3.5 bar.
Stop the engine.
Relieve pressure in the fuel system (perform operations similar to those described above).
Disconnect attachments and collect fuel in a container.
