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

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

Fuel pump / fuel level sensor

On models with petrol engines the fuel pump together with the fuel level sensor are established in a fuel tank. On a design the fuel level sensor consists of a potentiometer and the related float. At reduction of amount of fuel the float of the sensor falls and, increasing resistance of a potentiometer, lowers tension on the index of level of the fuel, located on a combination of devices.
