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 open by fire-dangerous light devices and do not smoke.
  • Before removal of a fuel tank, merge from it fuel. Clear a fuel tank of fuel steams.
  • Uncover with топливоналивной mouths of a fuel tank to level pressure in a tank with atmospheric pressure.


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

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

    Disconnect a wire of "weight" 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 топливоналивной mouths and a hose of alignment of pressure of steams of fuel.
    Support a fuel tank a jack.
    Turn on self-locking nuts and remove tapes of fastening of a fuel tank.
    Remove a fuel tank.

Close all opened apertures of a fuel tank to exclude an exit from a tank of steams of fuel.

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



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



    Establish a fuel tank and fix its tapes.
    Connect compensating hose to a mouth of a fuel tank, having pulled it approximately over 40 mm.
    At hose connection наполнителя 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 of steams of fuel and a returnable hose. Attach a hose of giving of fuel as is shown in drawing.
    For connection of a pressure head hose with the fuel pump, temporarily tighten накидные nuts by hand, then tighten their moment of an inhaling recommended by the specification. At a tightening of nuts be cautious not to bend or to overwind a tube and to avoid damage of the fuel pump.
    Connect a socket of the electric fuel pump.
