Checking the fuel lines
Caution: Check all fuel line connections for moisture or stains that could indicate fuel leakage.
Fuel filter replacement
1. Disconnect a wire from the negative plug of the storage battery.
2. Follow the procedures described in subsection "Before repair work" in chapter "fuel injection system".
3. Remove the fuel filter in the sequence shown in the figure.
1 - connector,
2 - fuel hoses,
3 - manual fuel pump,
4 - fuel filter (P/N - WE01-13-ZA5A),
5 - water presence sensor,
6 - drain plug,
7 - sealing ring (P/N - R2L1-13-ZA7),
8 - seal (P/N - R2L1-13-ZA2).
4. Apply fuel to the rubber seal of the new filter.
5. Install the fuel filter. After touching the body with the filter O-ring, tighten the filter by hand 3/4 turn.
6. Carry out the procedures described in the chapter "fuel injection system" section "After repair work".
7. Remove air from the fuel system.
8. Check fuel lines and connections for leaks.
Water sensor installation note
1. Lubricate the sensor O-ring with fuel.
2. Install the sensor in the fuel filter and tighten it by hand.
Bleeding air from the fuel system
Attention: if the fuel tank was repaired or other repairs were carried out in which the fuel was completely drained from the fuel tank, as well as if the fuel was completely used up during engine operation, then, in order to prevent air from entering the fuel system, it is recommended to pump fuel before starting the engine into the fuel lines using the manual priming pump located on the fuel filter.
Note: To prevent damage to the starter and battery, do not rotate the crankshaft with the starter for more than 30 seconds and pause for 5-10 seconds before re-rotating.
Rotate the crankshaft with the starter until the engine starts.
Removing water from the fuel system
Note: During diesel operation, the fuel filter separates water from diesel fuel to prevent damage to fuel system components "Common Rail". When about 0.13 liters of water accumulates in the fuel filter, the water in the fuel filter indicator lights up on the instrument cluster. The indicator informs the driver about the need to remove water from the fuel filter.
1. Disconnect a wire from the negative plug of the storage battery.
2. Follow the procedures in section "Before repair work" in chapter "fuel injection system".
3. Place a suitable container under the fuel filter.
4. Loosen the drain plug located on the bottom of the fuel filter one turn by hand.
5. While pressing the fuel priming pump with your hand, drain the water.
6. Tighten the drain plug.
