Sensor on the right side of the fuel tank

1. Loosen 4 screws and remove the cover.

When installing, pay attention to the gasket.

2. Disconnect the connector. Clamp the fuel line, loosen the clamp and remove the fuel line (on gasoline engines - the supply line, on diesel engines - the drain line).





3. Remove the nuts, lift the cover as far as possible and fold it upward.

Place the connecting hose under the cover without securing it.

4. Press the fuel pump latches simultaneously (black case). If the housing is white, remove the fuel pump from the housing.

When installing, make sure both clamps are securely fastened. Check the installation of the sealing ring on the connecting nipple and, if necessary, press it carefully into place.

The sensor is supplied assembled with connecting hoses and connectors.

7. Disconnect both connectors (1) on the fuel pump. Loosen the clamp (2) and carefully disconnect the spiral hose, avoiding damage to the pump nipple.

8. Installation is carried out in the reverse order. Before installation, straighten the connecting hose and cable (1) between the lid (2) and fuel pump (3) to avoid tension.
