Check of a condition and replacement of fuel lines and them штуцерных connections

Remember that gasoline is extremely an inflammable liquid!

At work with power supply system components observe all taken measures of fire safety. Do not smoke! Do not come nearer to a place of work with open fire or the redurable not protected by a lamp shade!

Do not make system service in the premises equipped working on natural gas and heating devices equipped with a control torch (such as водогреи and dryers for clothes).

Do not forget that gasoline is among cancerogenic substances, i.e., - the substances promoting development of a cancer!

Try not to suppose fuel hit on open sites of a body, use rubber protective gloves, at casual unforeseen contact to fuel carefully wash out hands warm water with soap.

Immediately collect the spilt fuel and do not put the rags impregnated with PETROLEUM PRODUCTS near to sources of open fire.

Remember that the power supply system equipped with injection of fuel of models constantly is under pressure.

Before to start a detachment of fuel lines, dump residual pressure in system.

At service of components of the power supply system put on goggles. Constantly hold near at hand the class fire extinguisher In!

Lines of a fuel path of the power supply system are laid between a petrol tank and an impellent compartment. Steel tubes and flexible fuel hoses fasten to the bottom of the car 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 release of the fulfilled gases), try to take advantage of a case and to check up a condition of fuel lines and them штуцерных connections.

The scheme of a lining of lines and placing of components of a fuel path

1  — the  Electromagnetic valve of a purge of coal adsorber EVAP
2  —  Perekidnoj the valve
3  — the  Electromagnetic valve of management of pressure
4  — the  Socket of fast joining
5  — the  Fuel pump
6  — the  pressure Gauge in a fuel tank

7  — the  Electromagnetic valve of management of ventilation EVAP
8  — the  Air filter
9  — the  Coal adsorber
10  —  Zapornyj the fuel valve
11  — the  Fuel tank
12  — the  Fuel filter


1. Attentively examine all hoses and tubes of a fuel path on presence of cracks, twisting, deformations and other mechanical damages.
2. At revealing of signs of internal pollution or passableness infringement corresponding section of a fuel path it is necessary to remove and blow compressed air.
3. Make sure of reliability of a tightening of all штуцерных connections of hoses and metal tubes of a fuel path.

Steel tubes


1. Use as replaceable sections only high-strength steel tubes of manufacture of the proved manufacturers.
2. Remember that copper and aluminium tubes are not capable to sustain vibrating loadings arising while in service 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 equipped carving штуцерными nozzles of section of metal tubes. At easing and a tightening штуцерных connections use two wrenches to avoid проворачивания a reciprocal part of a socket. Without fail check a condition used for hermetic sealing штуцерных connections of sealing rings. 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 the firm components calculated on high internal pressure.

Flexible fuel hoses should be laid not more close than in 10 sm from components of system of release of the fulfilled gases and is not closer than in 25 sm from каталитического than the converter. Watch, that fuel lines did not adjoin with кузовными elements and suspension bracket components. The minimum admissible size of a backlash makes 6.3 mm.



1. Dump pressure in the power supply system (see Has undressed pressure Dump in the power supply system).
2. Liberate section of a fuel path subject to dismantle from intermediate clamps of its fastening to the car bottom.
3. In most cases flexible hoses fasten to metal lines by means of collars of spring type. For отпускания a collar compress its flat-nose pliers and shift upwards on a hose. Deformed at release the collar is not subject to a reuse and should be replaced. Track, that at connection the hose has been tense on a tube at least on 2.5 sm, in the correct image establish a fixing collar.
4. In some штуцерных knots sockets of fast joining are used, - for отпускания such socket it is necessary to compress its lock uvulas and to pull the connected lines every which way.

Needlessly do not remove the case of a socket with штуцерной a part of a metal tube as it leads to easing of keeping effort developed by it.

5. Installation is made upside-down. On sockets of fast joining track for защелкиванием both lock uvulas in reception flutes.


In case of damage of a metal or flexible fuel line it is necessary to replace the failed section only firm a corresponding standard size.
