GENERAL INFORMATION, Precautions when working with electrical equipment.
Removing
1. Remove all fuel from the tank.
Td6 ENGINE FUEL SUPPLY, ADJUSTMENTS, Draining fuel from the fuel tank.
2. Disconnect "mass" battery wire.
3. Turn away 4 nuts and remove the right cover of a body for access to a fuel tank.
WARNING: Fuel vapors are highly flammable, and in an enclosed area they are also toxic and explosive. There must be a fire extinguisher in the room where fuel is removed from the fuel tank (foam, carbon dioxide, gas or powder).
4. Disconnect the connector from the fuel priming pump.
5. Prepare suitable containers for draining residual fuel from the pipelines.
WARNING: Fuel leakage is inevitable during this operation. Take safety precautions to prevent fire or explosion.
6. Remembering the location of the fuel hoses, disconnect the injection and drain pipes from the fuel priming pump. Loosen the clamp and disconnect the pump ventilation tube.
CAUTION: Before disconnecting any system elements, make sure that the places immediately adjacent to the elements to be disconnected are free of dirt. Immediately after disconnection, close the open ends of the pipelines with plugs to prevent foreign particles from entering the system.
7. Tie together and lay aside the pipelines and ventilation tube so as not to interfere with the removal of the fuel priming pump.
8. Working through the left inspection hole of the fuel tank, disconnect the coupling from the fuel priming pump. The coupling is made together with the electrical connector.
9. Clean the surface of the lock ring from dirt and dust.
10. Using tool LRT-19-009, remove the lock ring from the fuel tank body.
11. Carefully remove the fuel priming pump from the tank. When reinstalling, replace the old pump seal with a new one.
12. Prepare suitable containers for draining residual fuel from the pipelines.
13. Disconnect the left fuel level sensor and remove it from the tank.
Installation
1. Clean the surfaces adjacent to the inspection holes of the fuel tank from dirt and dust.
2. Clean the fuel pump housing and install a new seal.
3. Connect to the fuel priming pump the coupling of the pipeline coming from the left fuel level sensor. The coupling is made together with the electrical connector of the sensor.
CAUTION: After connecting the coupling, the lock must be in the position "collected".
4. Carefully insert the priming pump into the fuel tank. Install it
in the correct position, do not distort the seal. Working from the left inspection hole, check the position of the lower end of the pump.
5. Using tool LRT-19-009, install the lock ring and tighten it to 35 Nm (26 lb ft).
6. Connect to the pump fuel hoses and a tube of ventilation.
7. Connect the electrical connector to the fuel priming pump.
8. Reinstall the right body cover for access to the fuel tank, tighten the fixing nuts to a torque of 10 Nm (7 lb ft).
9. Lower the passenger compartment carpet.
10. Connect "mass" battery wire.
11. Fill the fuel tank.

12. Connect the TestBook/T4 diagnostic tool, verify that the new fuel level sensors are working properly.
