Fig. 2.227. Cover of a jellied mouth of a fuel tank

The cover of a jellied mouth of a fuel tank is equipped with a safety valve for emission prevention паров fuels in the atmosphere (fig. 2.227).

Removal and drive installation

managements of supply of fuel

Fig. 2.228. Details of a drive of management of supply of fuel

Details of a drive of management are shown by supply of fuel on fig. 2.228.

Removal

Fig. 2.229. Bolts of fastening of the plug of a cable of a drive of a butterfly valve

Remove the plug (fig. 2.229) and an internal part of a cable from the lever of a pedal of an accelerator.

Fig. 2.230. Bolts of fastening of an arm of the lever of a pedal of an accelerator

Separate the electric socket of the switch of a pedal of an accelerator, unscrew bolts of fastening of an arm of the lever of a pedal of an accelerator (fig. 2.230) and remove an accelerator pedal.

Check internal and external parts of a cable on existence of damages.

Check smoothness of moving of a cable.

Check the lever of a pedal of an accelerator on existence of deformations.

Check a returnable spring on existence of damages.

Check connection of the plug to the metal holder.

Check operability of the switch of a pedal of an accelerator.

Fig. 2.231. Points of drawing of konsistentny greasing

At installation of a returnable spring and the lever of a pedal of an accelerator put universal konsistentny greasing in all points of a friction of the lever (fig. 2.231).

Fig. 2.232. Places of drawing of hermetic (are shown by shooters)

Put hermetic in openings under bolts of fastening of an arm of the lever of a pedal (fig. 2.232) and tighten bolts the specified moment.

Moment of an inhaling of bolts of fastening of an arm of the lever of a pedal of an accelerator: 8–12 N · m.

Reliably establish the plastic plug of a cable of management of a butterfly valve on the end of the lever of a pedal.

Fig. 2.233. Places of drawing of hermetic (are shown by shooters)

Put universal greasing on a cable tip (fig. 2.233).

Fig. 2.234. Fuel tank

The system of supply of fuel consists of a fuel tank (fig. 2.234), the fuel pump, the fuel filter, топливопроводов and a fuel stage with nozzles.

Combine a back of a back seat on a pillow, then cast away the combined seat forward

Screw-driver open the hatch of the fuel pump in the body bottom.

For pressure dumping in fuel pipelines and hoses disconnect the electric socket from the fuel pump, start the engine and wait, while the engine will not stop.

NOTE For prevention of emission of fuel before a detachment of the pipeline and a hose of supply of fuel it is necessary dump pressure in system.

Disconnect a wire from a minus conclusion of the storage battery.

Disconnect a hose of a high pressure from the target union of the fuel filter, disconnect the conductor of branch of a static electricity.

ATTENTION For prevention of emission of fuel under the influence of residual pressure to cover hose connection by rags.

Establish the car on the lift.

Disconnect from a tank a jellied hose and a perelivny tube.

Establish under a tank a jack.

Fig. 2.235. Collars of fastening of a fuel tank to the bottom of a body of the car

Remove collars of fastening of a fuel tank to the bottom of a body of the car (fig. 2.235).

Accurately remove a fuel tank.

Check hoses and pipelines on existence of cracks or damages.

Check serviceability of a stopper of a jellied mouth of a tank.

Check a fuel tank on existence of deformation, corrosion or cracks.

Check, whether is not present in a tank of dirt and extraneous subjects.

Check the internal filter of a tank on existence of damages and pollution.

Check operation of the double-thread valve.

For check of the on-off valve slightly to blow in it from entrance and target branch pipes. If air passes after small resistance, the valve is serviceable.

Installation

Be convinced that laying is reliably pasted to a tank then establish a tank and tighten самоконтрящиеся nuts of fastening of collars.

Attach perelivny a hose to a tank and a bulk mouth, having inserted it on depth about 40 mm.

Fig. 2.236. Scheme of connection of a bulk hose

Bulk hose attach to a tank it shorter, not goffered part (fig. 2.236).

Attach parootvodny a hose.

Attach a hose of a high pressure to the fuel pump, without allowing thus a hose perekruchivaniye.

Connect the electric socket of the fuel pump.
