6.3.2.6. Fuel system


The prevention

Look safety measures in subsection 6.3.2 before the work beginning.

The following operation will let out pressure from fuel system – do not forget that in system there will be a fuel, therefore, observe necessary safety measures at a detachment of elements of system. Use pure rags which are necessary for wrapping up round connections, for fuel gathering. Utilise the rags which have absorbed fuel, with care. Stop up or close open fuel tubes for prevention of leak of fuel or hit in dirt system.


The fuel system described in this subsection, consists of the fuel pump established in a fuel tank, the fuel filter, a fuel collector and injectors, a pressure regulator, and also, metal tubes and the flexible hoses connecting these elements. All these elements contain fuel which is under pressure when the engine works and / or when ignition is switched off. Pressure remains in system during some time after coupling deenergizing, and it is necessary for letting out before removal of elements of system.

Pressure release
