Check from time to time the reliability of the tanks' fastening
and, if necessary, tighten the fastening bolts.
To be flushed, the fuel tanks shall be dismantled from the
vehicle.
Prior to dismantling of the tanks from the vehicle, do the
following:
- disconnect the rechargeable battery;
- drain the fuel by unscrewing the plugs on the tanks bottoms;
- open the hatch in the body's floor and disconnect the block
from the fuel level indicator sensor;
- disconnect the fuel lines tubes and hoses.
Then unscrew the bolts of the fuel tanks bands, bend the
bands down, so they do not obstruct the tank lowering, and

The tank shall be re-installed in reverse order.
Pay special attention to the fuel system hermetic-tightness
and the reliability connection to the "ground".
It is not recommended to operate the vehicle, if there is less
than 5 liters of fuel in the right-side fuel tank.
When traveling over steep climbs, there must be at least 20 liters

(unscrew the orifice), flush it and purge with air.
The jet pump is fastened on the fuel hoses near the frame's
right side member.
Joint leak shall be rectified through tightening of the worm
drive joints of clamps, or by replacement of faulty components.
Upon completion of any fuel feed system maintenance
operations related to tightening of clamps' connections, removal
