       PREVENTIONS
Gasoline is extremely flammable, during the work with elements of fuel system use of fire, the sparking devices opened by fire-dangerous light devices and smoking is forbidden. Avoid emergence of sparking at the address with wires and electric devices.
As gasoline is cancerogenic substance, it is necessary to exclude its hit on a body and a paint and varnish covering of the car. Otherwise immediately wash out an affected area water with soap.
The fuel system is under constant pressure therefore before a detachment of pipelines surely dump pressure in fuel system.


You make dropping pressure in fuel system as follows:
– remove a stopper from a jellied mouth of the fuel tank therefore pressure in the fuel tank will be leveled with atmospheric;
– for access to the block of the fuel pump / sensor of level, remove a back seat and a cover of the hatch. Disconnect the electric socket from the block of the fuel pump / sensor of level;
– launch the engine and leave it to work until the stop connected with lack of fuel in the distributive fuel highway;
– switch off ignition and disconnect a wire of "weight" from the rechargeable battery.
As a result of the performed operations pressure in fuel system is dumped. Close any connection of fuel system pure rags and, being careful, smoothly turn off a connecting nut.
After work on fuel system connect the electric socket to the block of the fuel pump / sensor of level and a wire of "weight" to the rechargeable battery.
