Cleaning and repair of the fuel tank

Any works on repair of a tank or jellied mouth have to be carried out by the highly skilled personnel having experience in so dangerous and responsible works.

Even after cleaning and washing of fuel system residual explosive couples which can ignite during repair of a tank can accumulate.

If the fuel tank is removed from the car, it should not be stored in those places in which there is a danger of explosion of vapors from a spark or naked flame.

Observe extra care in a garage with a supply of natural gas as antiemergency gas lighting can be a cause of explosion.

2. Establish a jack under the fuel tank.
3. Weaken a collar of a hose of a jellied mouth.
4. Disconnect hoses of system of collecting vapors of fuel from the fuel tank.
5. Turn off bolts of fixing collars and remove the fuel tank.
6. Installation is carried out upside-down removals.
