To prevent fuel leakage in the event of a vehicle collision, a safety valve is installed to prevent fuel leakage when the vehicle is overturned (rollover valve).
The fuel tank is made of plastic, resulting in a reduction in weight and an increase in anti-corrosion properties.
Removing
- Drain the fuel before removing the fuel tank. Clean the fuel tank of fuel vapors.
- Reduce the pressure in the fuel system.
- Remove the rear seat and protective cover.
- Disconnect the fuel hoses and electrical connector from the fuel pump unit.
- Unscrew the cover with a special key and remove the fuel pump unit (pic. 6.64).

- Disconnect the fuel supply flanks from the fuel tank.
- Turn out bolts and remove draft of adjustment of a convergence.
- Turn out bolts and remove thermoprotective casings.
- Disconnect the fuel tank fuel filler hose and the fuel tank equalization hose from the fuel tank.
- Install a jack under the fuel tank. While supporting the fuel tank, remove the nuts and remove the fuel tank straps. Lower the fuel tank and remove it from under the vehicle.
- Installation is carried out in the reverse order of removal, taking into account the following.
- Check that the fuel tank rubber gasket is not damaged or deformed, and then securely fasten the gasket.
Warning. If the rubber gasket is installed on the fuel pump unit, when the fuel pump unit is installed in the fuel tank, the lip of the rubber gasket will be damaged, resulting in fuel leakage (pic. 6.66).

Note. If the rubber seal is damaged or deformed, replace it.
- Apply soapy water to the inside of the gasket. Align the marks on the fuel pump assembly and the fuel tank, and install the fuel pump assembly into the fuel tank (pic. 6.67).

Warnings
- (1) Do not tilt the fuel pump when installing it.
- (2) Do not bite the gasket when installing it.
- Apply a soapy solution to the threads of the fuel pump unit cover and screw and tighten the cover with a special wrench to 49 Nm (see fig. 6.64).
Warnings. When tightening the cap, prevent the fuel pump unit from turning.
- Pour fuel into the tank.
- Check fuel system for leaks.
