Fuel tank of cars with petrol engines
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 pairs of fuel which are explosive therefore be careful.
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.
