Check of a condition and replacement of fuel lines and their shtutserny connections

See preventions at the beginning of pressure Sbrasyvaniye's Section in a power supply system.


 PERFORMANCE ORDER

1. Before starting service of fuel lines or their shtutserny connections it is necessary to dump pressure in a power supply system (see. Undressed Sbrasyvaniye pressure in a power supply system).
2. Lines of a fuel path of a power supply system are laid between a fuel tank and an impellent compartment. Steel tubes and flexible fuel hoses fasten to the car bottom by means of clips and screw fixture. Each time when the car rises over the earth with any purpose (for example, for survey or replacement of components of system of production of the fulfilled gases), try to use a case and to check a condition of fuel lines and their shtutserny connections. Attentively examine all hoses and tubes of a fuel path on existence of cracks, twisting, deformations and other mechanical damages.
3. At identification of signs of internal pollution or passableness violation the corresponding section of a fuel path is necessary for removing and blowing the compressed air. Without fail check also a condition of the mesh filter of a toplivozabornik of the pump (see. Section Check of a condition and replacement of the sensor of fuel consumption).

Steel tubes

Use as replaceable sections only high-strength steel tubes of production of the proved manufacturers.

Remember that copper and aluminum tubes are not capable to sustain vibrating loadings arising in use the car.

Do not forget that fuel lines on the models equipped with system of injection, should maintain high internal pressure.

Often in firm shops of automobile accessories it is possible to get the sections of metal tubes equipped with carving shtutserny nozzles. During the easing and a tightening of shtutserny connections use two wrenches to avoid a provorachivaniye of a reciprocal part of the socket. Without fail check a condition of shtutserny connections of sealing rings used for sealing. The worn-out or mechanically damaged rings at once replace. Try to use as replaceable components only firm details.

Flexible hoses

At replacement of fuel hoses use only firm components calculated on high internal pressure.


Flexible fuel hoses should be laid not closer than in 10 cm from components of system of production of the fulfilled gases and is not closer than in 25 cm from the catalytic converter. Watch, that fuel lines did not adjoin to body elements and suspension bracket components. The minimum admissible size of a gap makes 6.3 mm.

REPLACEMENT

 PERFORMANCE ORDER

1. The damaged sections of fuel lines (tubes or hoses) should be removed and replaced new, firm production.
2. Dump pressure in a power supply system (see. Undressed Sbrasyvaniye pressure in a power supply system).
3. Liberate section of a fuel path subject to dismantle from intermediate clamps of fastening it to the car bottom.
4. At the corresponding complete set release a collar (ы) and disconnect a hose (and) from the metal line (й). In case of need for release повращайте a hose on the union for simplification of its detachment.
5. Installation is made upside-down.
