To the high-pressure fuel pump, the fuel comes from the
right-side tank through the final fuel filter. As fuel is consumed,
the right-side tank is refilled from the left-side one automatically.
The plugs of the fuel tanks filling pipes necks are blind and
ensure tight packing.
The following is recommended, due to the specified features
of the fuel system design:
- when closing the tank filler necks, make sure the plugs are
in good condition, the sealing gasket is present and undamaged,
and ensure tight closing of the plugs through the application of
adequate force;
- for partial fuelling of the vehicle, start from the right-side
tank;
- monitor the fuel consumption with due account for variation
of the fuel amount in both tanks.

4, 22 (Fig. 9.17). Maintenance of the fuel tanks
includes periodic flushing of the fuel level indicator inlet tube
filter (right-side and left-side tanks) and flushing of the tanks
themselves.
From time to time, drain the settling by unscrewing the plug
in the tank bottom part.
