Attention: Follow the safety precautions (see section 1).
See also Chapter 1, Section 9.
1. The lines of the fuel path of the power system are laid between the fuel tank and the engine compartment. Steel tubes and flexible fuel hoses are attached to the underbody of the vehicle with clips and screw fasteners. Every time the vehicle is lifted off the ground for any purpose (e.g. to inspect or replace exhaust system components), try to take the opportunity to check the condition of the fuel lines and their fittings.
2. Carefully inspect all hoses and tubes of the fuel path for cracks, twists, deformations and other mechanical damage.
3. If signs of internal contamination or obstruction are detected, the corresponding section of the fuel path must be removed and blown with compressed air.
4. Be convinced of reliability of a tightening of all union connections of hoses and metal tubes of a fuel path. Use two wrenches when loosening and tightening bar connections to avoid turning the mating connector.
5. Be sure to check the condition of the o-rings used for sealing. Replace worn or mechanically damaged rings immediately. When replacing flexible fuel hoses, use only genuine high internal pressure components.
6. Flexible fuel hoses must be laid no closer than 10 cm from the components of the exhaust system and no closer than 25 cm from the catalytic converter. Keep fuel lines away from bodywork and suspension components. The minimum allowable gap is 6.3 mm.
7. To replace, release the section of the fuel path to be dismantled from the intermediate clamps securing it to the bottom of the vehicle. In most cases, flexible hoses are attached to metal lines with spring-type clamps. To release the clamp, squeeze it with pliers and slide it up the hose. A clamp deformed when released cannot be reused and must be replaced. Make sure that when connecting the hose is pulled over the tube by at least 2.5 cm, install the mounting clamp correctly.
Note: Some choke assemblies use quick-connect connectors, which may have different designs. In order not to damage such a connector, carefully inspect it and understand the principle of its operation. Unless necessary, do not remove the connector housing from the fitting part of the metal tube, as this leads to a weakening of the holding force developed by it.
8. In case of damage, metal or flexible fuel lines, as well as connecting fittings, cannot be repaired and must be replaced - try to use only branded spare parts of the appropriate size.
