Fuel tank.
1 - fuel filler cap, 2 - seal, 3 - fuel filler and drain hose assembly, 4 - fuel tank, 5 - fuel pump and fuel level sensor assembly, 6 - fuel level sensor, 7 - fuel pump, 8 - non-return valve and fuel cut-off valve assembly, 9 - fuel tank fastening tape, 10 - protective cover, 11 - canister, 12 - canister vent tube, 13 - canister safety valve, 14 - fuel vapor recovery system hose.
Withdrawal
1. To bleed residual pressure from the fuel lines and high pressure hoses, disconnect the fuel pump connector, then start the engine and let it run. After the engine stalls on its own, turn the ignition key to the "OFF (OFF).
Note: To prevent fuel splashing, make sure that the residual pressure in the high pressure fuel lines is reduced before disconnecting the main fuel pipes and hoses.
2. Disconnect a wire from the negative plug of the storage battery.
3. Remove the fuel filler cap.
4. Raise the car on the lift.
5. Remove the main muffler and, if necessary, the central pipe of the exhaust system.
6. Remove the fuel tank guard.
7. Remove the drain plug and drain the fuel from the tank.
8. Disconnect the fuel return hose and the evaporative emission system hose.
9. Disconnect the high pressure fuel hose from the fuel pump.
10. Support the fuel tank with a transmission telescopic stand or other temporary support.
11. Remove the two self-locking nuts holding the fuel tank in place and remove the two fuel tank straps. Disconnect the filler hose and drain hose from the fuel tank.
12. Disconnect the filler hose and drain hose from the fuel tank.
13. Remove the EVAP hose and fuel tank.
Examination
1. Check fuel hoses and tubes for cracks, kinks, deformation, fraying, or blockage. If there are signs of clogging or contamination of the fuel pipes located under the floor of the car, it is necessary to remove the corresponding section of pipes and blow it out with compressed air.
2. Check the serviceability of the cap valve and the condition of the fuel filler cap.
3. Checking the fuel cut-off valve (on the fuel tank).
Note: A fuel cut-off valve is installed to prevent fuel from leaking out of the tank in the event of an accident (car flip) to the fuel vapor line.
- A) Disconnect the EVAP hose and remove the fuel cutoff valve from the fuel tank.
- b) The valve is considered serviceable if, when the valve is slightly shaken up and down, the sound of the float moving inside is heard (knock).
- V) Turn over and slowly submerge the fuel cut-off valve into a container of water, blocking the valve fitting with your finger as shown in the illustration.
- G) Check that there are no air bubbles that air has been removed from the valve, then slowly remove the valve from the container.
- d) The valve is considered serviceable if after opening the fitting there is no water flowing out of the valve. In the event that water flows out through the fitting, the valve is considered faulty. If any problems are found, replace the fuel cut-off valve.
4. Checking the fuel tank.
- A) Check the fuel tank and its mounting for deformation, corrosion or cracks.
- b) Check the fuel tank for dust or foreign particles inside.
Note: If the inside of the fuel tank needs to be cleaned, use a neutral detergent.
- V) Check the in-tank pump fuel filter for damage or blockage.
5. Check that the two-way valve is working.
- A) Connect a hand vacuum pump to the two way valve.
- b) When a vacuum pump is connected to the intake side, a vacuum in the intake or exhaust guide lines is generated and maintained.
- V) When connected to the exhaust side, no vacuum is created.
Installation
1. Connect the drain hose and filler hose to the fuel tank so that the hose is put on the tube at a distance of about 40 mm from its edge.
2. When connecting the fuel filler hose, connect the short straight end of the hose to the side of the fuel tank tube.
3. Make sure the fastening is secure (welding) fuel tank buffers. Reinstall the fuel tank by tightening the self-locking nuts on the tank straps until the rear ends of the straps touch the vehicle body.
4. Connect the EVAP hose and fuel return hose. Connect the hose to the tube so that the hose is on the tube as shown in the figure.
5. Install the fuel pump with fuel level sensor assembly to the fuel tank. Tighten the fuel pump mounting screws to nominal torque.
- Tightening torque: 2-3 Nm
6. To connect the high pressure fuel hose to the fuel pump, first temporarily tighten the high pressure fuel hose union nut by hand, then tighten the nut to the specified torque.
Attention: be careful when performing this operation so that the fuel hose is not kinked.
- Tightening torque 30-40 Nm
Note: be careful when tightening the flare nut, do not twist or bend the fuel pipes to avoid damage to the connection of the pipe and the fuel pump fitting.
7. Connect a socket of the fuel pump.
8. Install and tighten the drain plug to the specified torque.
- Tightening torque: 15-25 Nm
9. After completing the work, fill the tank with fuel and activate the fuel pump (turn the ignition key to position "ON" (ON) for a few seconds), then check for fuel leaks.
