Fuel tank


  • Gasoline is explosive, therefore at work with elements of fuel system provide normal ventilation of a workplace, do not use fire, the sparking devices opened by fire-dangerous light devices and do not smoke.
  • Before removal of a fuel tank, merge from it fuel. Clear a fuel tank from паров fuels.
  • Uncover a toplivonalivny mouth of a fuel tank to level pressure in a tank with atmospheric pressure.


    Remove a pillow of back sitting and disconnect the socket of the fuel pump.
    Start up the engine and leave it to work till a stop connected with lack of fuel in the distributive fuel highway. As a result of the executed actions pressure in fuel system is removed.

For an exception of a razbryzgivaniye of fuel close a place of separation of fuel system pure rags and, being careful, smoothly separate pipelines.

    Disconnect a "weight" wire from the storage battery.
    Disconnect the top pressure head hose from the party of an exit of the fuel filter and a wire of removal of a static electricity. Lift the car. Disconnect a hose from a toplivonalivny mouth and a hose of alignment of pressure паров fuels.
    Support a fuel tank a jack.
    Unscrew самоконтрящиеся nuts and remove tapes of fastening of a fuel tank.
    Remove a fuel tank.

Close all opened openings of a fuel tank to exclude an exit from a tank паров fuels.

Even in an empty fuel tank there are pairs of fuel which are explosive therefore be careful. Provide normal ventilation of a workplace, do not use fire, the sparking devices opened by fire-dangerous light devices and do not smoke. As soon as possible clear a fuel tank from паров fuels.



    Check hoses and pipes on lack of cracks, an excess, deformation, aging and a contamination. Check functioning of a cover of a jellied mouth of a fuel tank. Clear a tank and check it on existence of traces of a rust, damages and cracks. Damaged or treated it is necessary for corrosion action to replace a fuel tank. Check an internal surface of a fuel tank on existence of pollution. Check the fuel filter on lack of a contamination or damages. Check operability of the limiter of overflow (the double-thread valve).
    Check operability of the double-thread valve, blowing it from two parties.



    Establish a fuel tank and fix it tapes.
    Connect compensating hose to a mouth of a fuel tank, having pulled it approximately over 40 mm.
    At connection of a hose of a filler it is necessary to connect the end with shorter direct pipe сл the parties of a fuel tank.
    Connect a hose of system of catching паров fuels and a returnable hose. Attach a hose of supply of fuel as is shown in drawing.
    For connection of a pressure head hose with the fuel pump, temporarily tighten cap nuts by hand, then tighten them the moment of the inhaling recommended by the specification. At a tightening of nuts be careful not to bend or to overwind a tube and to avoid damage of the fuel pump.
    Connect the socket of the electric fuel pump.
