Fuel system




A warning

See precautions in section 6.3.1 before proceeding.

The following operation will release pressure from the fuel system - do not forget that the system will remain the fuel, therefore, take the necessary precautions when disconnecting system components. Use a clean cloth to be wrapped around the joints, to collect fuel. Dispose of rags, absorbed fuel with caution. Plug the open or close the fuel pipes to prevent leakage of fuel or hit in dirt system.


The fuel system includes a fuel pump installed in a fuel tank, the fuel filter, the injector and the pressure regulator, as well as metal pipes and hoses connecting these elements. All of these elements comprise a fuel which is under pressure when the engine is running and / or when the ignition is off. The pressure is maintained in the system for some time after the clutch, and it is necessary to release before removing the elements of the system.
