Removal and installation the fuel filter
Attention.
- Leaks in fuel lines in a pressurized system are dangerous. Fuel can ignite and cause equipment damage, serious injury, or even death. Fuel can also come into contact with human skin and eyes. To prevent this, it is essential to perform a pressure relief procedure in the fuel system.
- A person carrying a static charge can cause a fire or explosion, which could result in death or serious injury. Before working on the fuel system, you must discharge static electricity by touching the vehicle body.
- If fuel gets on engine parts, it may cause damage to those components or cause a fire. Be sure to wipe up any spilled fuel with a clean rag.
- If the fuel does not pass through the fuel filter, this may cause a malfunction of the fuel system. In this regard, it is necessary to ensure that the fuel hoses are not installed incorrectly. It is imperative to perform the procedures after servicing the fuel system (see the relevant section above) before installing fuel hoses.
1. Disconnect the negative battery terminal.
2. Perform the procedure for preparing for servicing the power supply system.
3. Remove the decorative engine cover.
4. Remove the battery.
5. Remove the components in the order shown in the figure.
1. Sediment sensor connector.
2. Fuel heating connector (versions with fuel heating).
3. Main fuel hose No.1.
4. Main fuel hose No.2.
5. Fuel filter.
6. Drain plug.
7. Sump sensor.
8. Fuel heating (versions with fuel heating).
6. Installation is carried out in the reverse order of removal.

Visually inspect the fuel filter for cracks, damage, or rust. Cracks or damage may be the cause of fuel leaks. If any defects are found, replace the fuel filter with a new one.
Draining water from the fuel filter
1. Remove the fuel filter.
2. Loosen the drain plug at the bottom of the fuel filter.
3. Drain the water.
4. After draining the water from the filter, tighten the drain plug securely by hand.
Checking the fuel heating
1. Disconnect the negative battery terminal.
2. Perform the procedure for preparing for servicing the power supply system.
3. Remove the heating element from the fuel filter.
4. Connect the vacuum pump to the fuel heater.
5. Having created a vacuum of 26.7-40.0 kPa in the fuel heater, measure the resistance between terminal B and the heater body.
Note: Nominal resistance of fuel heater: 0.5-2.0 Ohm.
6. If the measured value is not within the norm, replace the fuel heater with a new one.
Checking the sump sensor
1. Disconnect the negative battery terminal.
2. Perform the procedure for preparing for servicing the power supply system.
3. Drain the fuel from the fuel filter.
4. Remove the sump sensor.
5. Make sure that there is no conductivity in the circuit when the float is pulled out.
If the circuit is shorted, replace the sump sensor with a new one.
