Removal

PERFORMANCE ORDER
1. Through a toplivozalivny mouth pump out from a fuel tank fuel.
2. Lift the bottom edge of the consolidation located round a jellied mouth and unscrew the fastening screw.
3. Lift a back part of the car and fix on supports.
4. Unscrew a bolt of fastening of a pipe of a toplivozalivny mouth to the car bottom. Cut connecting collars or brackets which other hoses to a pipe of a toplivozalivny mouth fix. Release collars and disconnect hoses of filling of a fuel tank and ventilation from the bottom end of a pipe of a toplivozalivny mouth. Disconnect hoses of ventilation of small diameter from connecting couplings on the top end of a pipe.
5. Check that all elements connected to a pipe, are removed or disconnected and remove a pipe of a toplivozalivny mouth from under the car.
6. For check of operability of the valve interfering leak in a pipe of a toplivozalivny mouth, overturn a pipe and fill in in the bottom connecting coupling gasoline. If the valve is serviceable, gasoline should not follow on the other side of a pipe. If gasoline follows, means, the valve is faulty and it is necessary to replace completely a pipe of a toplivozalivny mouth.

Installation

Places of connection of hoses of ventilation to a pipe of a toplivozalivny mouth

And – a hose of the coal filter;

In – a hose of ventilation of a fuel tank


PERFORMANCE ORDER
1. Installation is made in sequence, return to removal taking into account the next moments:

– check a condition of all hoses and collars of fastening and if necessary, replace them;
– connect hoses of ventilation of a fuel tank to connecting couplings in the top end of a pipe of a toplivozalivny mouth, and also a hose from the coal filter to the top connecting coupling and the hose of ventilation going from a fuel tank to the bottom connecting coupling (see drawing);
– replace all brackets cut at removal and the collars, fixing hoses to a pipe of a toplivozalivny mouth;
– check, that there were no leakages of fuel at its filling in a fuel tank.
