Toyota RAV4>> Fuel system and system of release of the fulfilled gases>> The general check of fuel system>> Check of fuel tubes, hoses and their connections
Check of fuel tubes, hoses and their connections carry out as follows.
Dump pressure in fuel system.
Metal fuel tubes are laid under the bottom of the car and fixed by clips and screws-samorezami. Periodically examine them on absence of leaks and damages.
If at replacement of the fuel filter in it and fuel pipelines there is a dirt, necessarily disconnect pipelines and blow their compressed air. Also check up a condition of the mesh filter on the block of the fuel pump.
Never use copper or aluminium tubes instead of steel tubes established on the car as they can not sustain vibration at car operation.
As fuel tubes are under a high pressure, they demand special service.
Some fuel tubes have carving connections with sealing rings which are necessary for unscrewing before service or replacement of components. In such connections are used конусные nuts which nuts at a tightening, in addition press out connection. Sealing rings check up on absence of cracks and damages and if necessary replace. If replacement of steel tubes is spent, establish only original tubes.
Flexible fuel hoses should settle down on distance not less than 100 mm from elements of system of release of the fulfilled gases and 250 mm from catalytic neutralizer.
On some models establish nylon fuel hoses with quick-detachable connectors. In this case in need of replacement of one hose spend replacement of hoses complete with quick-detachable connectors.
Replacement of fuel tubes/hoses make as follows.
Dump pressure in fuel system.
Release all clips, крепящие a tube/hose to a car body.
On usual connections of a steel fuel tube and a hose, loosen the a collar, then extend a tube of their hose. Проворачивание every which way a tube and a hose facilitates separation process.

Fig. 5.4. Pressing of clamps and extraction of a tube from a quick-detachable connector

If connection of hoses is carried out by a quick-detachable connector, open and remove a clip, then one hand from two parties press clamps, and other hand take a tube from a connector (fig. 5.3, 5.4).
At connection of tubes and hoses necessarily establish new sealing rings (if it is provided by a design).
On quick-detachable connectors combine a tube with a connector and insert a tube into a connector to защелкивания its clamps.

Fig. 5.5. Usual connection of a hose with a steel tube: 1 – a steel tube; 2 – a hose; 3 – a collar

At usual connection of a hose with a steel tube pull a hose over a tube and fix connection by a collar (fig. 5.5).
