Removal

Fuel level sensor arrangement on models with a body the Sedan
And – the electric socket of the sensor;

In – a nut of fastening of the sensor


PERFORMANCE ORDER
1. Removal of the fuel level sensor is desirable for making on an empty fuel tank. If the fuel tank is completely filled with fuel, pump out from it at least 8 liters of fuel before fuel level sensor removal.
2. Remove a weight wire from the accumulator.
3. On the Sedan models remove trunk floor furnish, take clamps and remove the prokladochny panel of a fuel tank. On the Versatile person models remove forward furnish of a luggage carrier or a back of the third row of seats. Take clamps and lift a rug of a luggage compartment.

5. Unscrew a nut of fastening of the sensor and take the fuel level sensor from a fuel tank.
6. Remove a sealing ring from an opening for fuel level sensor installation.

Installation

PERFORMANCE ORDER
1. Installation is made in sequence, return to removal taking into account the next moments.
2. Before installation of the new fuel level sensor remove from it a protective tape and take blocking pin.
3. Replace a sealing ring of the fuel level sensor.
4. Tighten a nut of fastening of the fuel level sensor the demanded moment.
5. Check correctness and reliability of connection of the electric socket to the sensor.
6. Before installation of the prokladochny panel of a fuel tank start the engine and check that there are no leakages of fuel about the fuel level sensor.
