The prevention

Gasoline extremely fire - also is explosive, therefore it is necessary to show care at work on any part of fuel system.

Works on fuel system are necessary for making in well aired premise for what it is possible to open all windows and doors for draught creation.

At work on fuel system do not use open fire, electric welding and tools, at work with which sparks can be formed. Check up that in immediate proximity from a workplace there is a charged fire extinguisher.

For protection of eyes against hit in them of fuel use points. At fuel hit on a skin wash out this place a plentiful quantity of water.

The capacity in which there is a fuel, contains steams of fuel and is potentially explosive.

At work with fuel system observe cleanliness as the dirt which has got to channels of fuel system, can block them that will break normal work of the engine.

Front-wheel cars with diesel engines in a fuel tank do not have fuel pump. At all-wheel drive cars with diesel engines in a fuel tank the fuel pump is established.

Before removal of a fuel tank pump out from a tank fuel.

Removal of a fuel tank make from under the car. For support of a fuel tank use a jack.

Even at an empty fuel tank there are steams of fuel which are explosive, therefore be careful.

After installation of a fuel tank start the engine and check up tightness of fuel system.
