GENERAL INFORMATION

Prevention

Gasoline extremely fire - also is explosive, therefore it is necessary to show care at work on any part of fuel system.

Works on fuel system are necessary for making in well aired room for what it is possible to open all windows and doors for draft creation.

At work on fuel system do not use open fire, electric welding and tools, at work with which sparks can be formed. Check that in close proximity to a workplace there is a charged fire extinguisher.

For protection of eyes against fuel hit in them use points. At fuel hit on skin wash out this place a plentiful quantity of water.

The capacity in which there was a fuel, contains pairs of fuel and is potentially explosive.

At work with fuel system observe purity as the dirt which has got to channels of fuel system, can block them that will break normal operation of the engine.


Removal

PERFORMANCE ORDER
1. Through a toplivozalivny mouth pump out fuel from a fuel tank.
2. Lift a back part of the car and fix on supports.
Prevention

It is undesirable to remove a fuel tank on the car established over a viewing hole as in a viewing hole pairs of fuel accumulate that can cause a damage to health.


3. Remove pressure in fuel system.
4. Remove a weight wire from the accumulator.
5. Working under the car, disconnect from a fuel tank submitting and returnable fuel hoses and a ventilation hose. Not to mix hoses at installation, mark them. Close the ends топливопроводов and openings in a fuel tank jams.

Removal of the prokladochny panel of a fuel tank

Arrangement of nuts of fastening of the left side of a fuel tank

Arrangement of nuts of fastening of the right side of a fuel tank

Fastening of a fuel mouth to the body panel

PERFORMANCE ORDER
1. Remove the big rubber consolidation closing branch pipes of a fuel tank.
2. In a luggage compartment take percussion caps and move aside a carpet. Release clamps and fastenings and remove the prokladochny panel of a fuel tank (see fig. Removal of the prokladochny panel of a fuel tank).
3. Disconnect the electric socket from the fuel level sensor and take wires from fastening brackets.
4. Unscrew nuts of fastening of a fuel tank, lift a tank and disconnect a hose fuel plum. Disconnect a toplivozalvny mouth from the panel of a body and remove a sealing ring and plugs (see fig. An arrangement of nuts of fastening of the left side of a fuel tank, the Arrangement of nuts of fastening of the right side of a fuel tank, Fastening of a fuel mouth to the body panel).
5. Lift a fuel tank up, then move it back and take from a luggage compartment. Remove sealing strips.

PERFORMANCE ORDER
1. Take a back part of an exhaust system from rubber fastenings and support it boards not to deform connection of an exhaust system.
2. Disconnect the electric socket from the fuel level sensor.
3. Using a jack, through wooden whetstone support a fuel tank from below.
4. Unscrew nuts and remove a basic beam from a back part of a fuel tank. Unscrew the nuts, fixing arms on the forward party of a fuel tank, and remove washers and plugs (see fig. Fuel tank of the Versatile person models).
5. Slowly lower a jack with a fuel tank and disconnect from a tank a hose of ventilation of a jellied mouth. Disconnect a toplivozalivny mouth from the panel of a body and remove a sealing ring and plugs.

2. If in a fuel tank there is a deposit or water, remove the fuel level sensor and wash out a fuel tank a large amount of pure fuel. At existence on a fuel tank of mechanical damages restore a fuel tank in a specialized workshop or replace it.
Prevention

Do not restore a fuel tank independently with welding or soldering application as in a tank there are pairs of fuel which are explosive.


Installation

PERFORMANCE ORDER
1. Installation is made in sequence, return to removal taking into account the next moments.
2. Tighten all bolts and nuts the demanded moment.
3. For fastening of a fuel tank on the Versatile person models use only new самоконтрящиеся nuts.
4. Check correctness of installation of sealing strips.
5. Check correctness and reliability of connection of the electric socket of the fuel level sensor.
6. Make a trial trip, then check on absence of leakages of fuel all established elements.
