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


The cover of a jellied mouth of the fuel tank is equipped with the safety valve for prevention of emission of vapors of fuel in the atmosphere (fig. 2.227).
Removal and installation of the drive
managements of fuel supply

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


Details of the drive of management of supply of fuel are shown in fig. 2.228.

Removal

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


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

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, turn off bolts of fastening of an arm of the lever of a pedal of an accelerator (fig. 2.230) and remove an accelerator pedal.

Check of technical condition
Check internal and external parts of a cable for existence of damages.
Check smoothness of movement of a cable.
Check the accelerator pedal lever for existence of deformations.
Check a returnable spring for existence of damages.
Check connection of the plug to the metal holder.
Check operability of the switch of a pedal of an accelerator.

Installation

Fig. 2.231. Points of putting jellied lubricant


At installation of a returnable spring and the lever of a pedal of an accelerator apply universal jellied lubricant in all points of friction of the lever (fig. 2.231).

Fig. 2.232. Places of putting sealant (are shown by shooters)


Apply sealant 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 install 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 putting sealant (are shown by shooters)


Apply universal lubricant on a tip of a cable (fig. 2.233).

Removal and installation of the fuel tank

Fig. 2.234. Fuel tank


The fuel supply system consists of the fuel tank (fig. 2.234), the fuel pump, the fuel filter, fuel-supply lines and a fuel stage with nozzles.
Put a back of a back seat on a pillow, then cast away the put seat forward
The screw-driver open the hatch of the fuel pump in the body bottom.
For dumping of pressure in fuel pipelines and hoses disconnect the electric socket from the fuel pump, start the engine and wait until the engine stops.

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

Disconnect a wire from a minus conclusion of the rechargeable battery.
Disconnect a hose of high pressure from the output union of the fuel filter, disconnect the conductor of removal of static electricity.

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

Install the car on the elevator.
Disconnect a jellied hose and an overflow tube from a tank.
Establish a jack under a tank.

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


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

Check of technical condition
Check hoses and pipelines for existence of cracks or damages.
Check serviceability of a stopper of a jellied mouth of a tank.
Check the fuel tank for existence of deformation, corrosion or cracks.
Check whether is not present in a tank of dirt and foreign objects.
Check the internal filter of a tank for 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 output branch pipes. If air passes after small resistance, the valve is serviceable.

Installation
Make sure that laying is reliably pasted to a tank then install a tank and tighten самоконтрящиеся nuts of fastening of collars.
Attach an overflow 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 a corrugated part (fig. 2.236).
Attach steam discharge a hose.
Attach a hose of high pressure to the fuel pump, without allowing at the same time twisting of a hose.
Connect the electric socket of the fuel pump.
