The power supply system consists of the fuel tank, fuel-supply lines, the filter, the fuel pump and system of injection of fuel (the separate Section).

The fuel tank made of plastic is located at the car bottom before a back suspension bracket. The available reserve of fuel is shown to the driver on the dashboard. Ventilation of the fuel tank is carried out through the closed system of removal of air. At the petrol engine harmful vapors of gasoline gather in an adsorber and move in engine combustion chambers.

Style of driving of the car has significant effect on fuel consumption. Several councils for the reasonable handling of the accelerator pedal are given below.

PERFORMANCE ORDER
1. After start of the engine at once start even if it occurs on a frost.
2. At a car stop for a while more on 40 with, switch off the engine.
3. Move always on the highest transfer.
4. At the movement on long distances whenever possible support uniform speed. Avoid the movement at high speeds. Drive the car circumspectly. Without need you do not brake.
5. You transport the car excessive freight. If the luggage carrier is not used, remove it from a roof.
6. Check air pressure in tires. Do not allow excessive pressure decrease.
ATTENTION

During the work with fuel system it is necessary to observe the following security measures and purity:
Do not use naked flame near a workplace, you do not smoke and you do not hold any strongly warmed objects. There is a danger of accident! You keep in readiness the fire extinguisher.
You monitor normal ventilation of a workplace. Fuel vapors are poisonous.

7. The fuel system is under pressure. When opening system fuel can escape under pressure. Collect fuel by a rag. Use goggles.
8. Hose connections fasten by means of tape or tightening collars. Tightening collars need to be replaced with tape collars or collars of the last design surely. For installation of tape collars there is special adaptation, for example HAZET 796-5 or AUDI-1921.
9. Carefully clear connections and the places adjoining to them before opening.
10. Stack the removed details on a pure lining and close. Apply for this purpose polyethylene or paper. Do not apply for this purpose fibrous fabric!
11. Carefully close open details or put technological caps if repair lasts some time.
12. Establish into place only pure details. Take out spare parts from packing only just before installation. Do not apply details which were stored unpacked (for example, stored in a toolbox).
13. At open fuel system do not apply whenever possible compressed air. Whenever possible do not move at the same time the car.
14. Do not apply the sealants containing silicone. The silicone elements which got to the engine in the engine do not burn down and damage the oxygen sensor.
ATTENTION

Before removal of a tank merge from it fuel or pump out fuel the pump which is specially provided for this purpose.
The fuel tank is removed from the lower party of the car. Before a detachment of collars of fastening of a tank bring to it from below a jack and linings.
The empty tank is explosive and cannot be utilized in such look. Before utilization the tank has to be cut on a part. You watch that at the same time there was no spark. For this purpose hand over the fuel tank in the specialized enterprise.
After installation of a tank into place start the engine and check tightness of all connections.
