Check of a condition and replacement of fuel lines and their shtutserny connections
|
|
1. 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.
2. 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.
4. Make sure of reliability of a tightening of all shtutserny connections of hoses and metal tubes of a fuel path. |

Steel tubes
|
|
1. Use as replaceable sections only high-strength steel tubes of production of the proved manufacturers.
2. Remember that copper and aluminum tubes are not capable to sustain vibrating loadings arising in use the car.
3. Do not forget that fuel lines on the models equipped with system of injection, should maintain high internal pressure.
4. 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.
Replacement
|
|
1. Dump pressure in a power supply system (see. Undressed Sbrasyvaniye pressure in a power supply system).
2. Liberate section of a fuel path subject to dismantle from intermediate clamps of fastening it to the car bottom.
|
|
3. In most cases flexible hoses fasten to metal lines by means of collars of spring type. For an otpuskaniye of a collar compress it flat-nose pliers and shift up on a hose. The collar deformed at an otpuskaniye is not subject to a reuse and should be replaced. Track, that at connection the hose was tense on a tube at least on 2.5 cm, correctly establish a fixing collar (address to an accompanying illustration). |
4. In some shtutserny knots sockets of fast joining are used, – for an otpuskaniye of such socket it is necessary to compress his lock uvulas and to pull the connected lines in different directions.
|
|
Needlessly do not remove the socket case from a shtutserny part of a metal tube as it leads to weakening of holding effort developed by it. |
5. Installation is made upside-down. On sockets of fast joining track a zashchelkivaniye of both lock uvulas in reception flutes. |
|
Repair
In case of damage of the metal or flexible fuel line it is necessary to replace the failed section only firm the corresponding standard size.
