Contents: Removal ⬇ Installation ⬇
In cars produced since September 1991, the fuel level sensor is made of plastic. Removal and installation of plastic and metal sensors is performed in the same way. They are interchangeable.
Attention! When removing the sensor, the fuel level in the tank must be at a minimum (otherwise the fuel will leak out). To do this, you either need to use up the remaining fuel while driving, or pump it out through the filler neck using an additional pump.
Warning! Gasoline vapors are toxic! Ensure good ventilation of the workplace.
Warning! Do not allow open flames or sparks near the work area. There is a risk of fire!
Removal
Disconnect the ground wire from the battery.
Raise the vehicle and place it on supports.
Loosen the clamps and disconnect the fuel hoses, after marking them with adhesive tape.
For vehicles manufactured before August 1991: Disconnect the wires from the sensor.
