The gauge of level of fuel

The protective flange of a fuel tank located under the bottom of a luggage compartment

1 – the bringing pipeline to injection system;
2 – drain топливопровод from injection system (arrows specify in fixing plates for removal of it топливопровода);

3 — the tip of the fuel pump and the fuel gauge.

It is shown on an example of the 5-cylinder engine:

1 – the pipeline to a tank with the activated coal;
2 – the electromagnetic valve;
3 – топливопровод to the case of throttle knot.

The arrow specifies in the electromagnetic valve of a tank with the activated coal of model with the 6-cylinder engine.

The tank with the activated coal is located behind in the right forward wheel niche (on an illustration it is shown at removed подкрылке).

Position of installation of a protective flange: the arrow on a flange (1) should be opposite to a mark in a fuel tank (2).

On an illustration the removed protective flange (1) is shown:

2 – an electric wire of the fuel pump;
3 – a wire of the gauge of the indicator of quantity of fuel;
4 – the drain pipeline in a fuel tank;
5 – the fuel accumulator (only in models with the 5-cylinder engine and system of injection KE-III-Jetrolic).

The sediment bowl represented here is usually pasted in a fuel tank; on an illustration it is shown for the best presentation separately. Removal of the fuel gauge (1) is possible after pressing of the button (arrow). Thus occurs разблокирование. The gauge can be extended now.

The fuel gauge is established from above in the case топливозаборника, located inside in the middle of a fuel tank. The description of a way of its action you will find Devices and auxiliary devices in the head.

By the way, depending on various forms of a fuel tank there are various fuel gauges for front-wheel and all-wheel drive models. A distinction sign: the gauge with a rectangular float – front-wheel model, with a spherical float – all-wheel drive model.

 The help: the indicator of level of gasoline is not the high-precision device. Incorrectly showing gauge can be corrected indicator regulation on a control panel (the head Devices and auxiliary devices).

Removal of the fuel gauge

 Important: the fuel tank should be filled a maximum to 2/3, differently fuel will pour out!


  1. To turn on aside a rug of a luggage compartment.
  2. To turn off a black protective cover.
  3. To remove the multicontact tip.
  4. To squeeze fixing plates on a connector drain топливопровода and to remove топливопровод.
  5. To turn off топливопровод fuel givings.
  6. To turn off plastic накидную a nut. More often it sits very strong. Therefore it is necessary to put probably more stupid screw-driver to one of nut edges and to weaken a nut easy blows of a hammer on a handle core. If necessary to apply on other sides.
  7. Now it is possible to raise a protective flange a little.
  8. If it is necessary, to squeeze on a flange inside (as already it has been made outside) fixing plates drain топливопровода and to extend it in a direction downwards.
  9. Now to lower a hand in a fuel tank and to pull out the gauge from the case топливозаборника, simultaneously pressing "doggie".
  10. To disconnect the tip of the fuel gauge on a protective flange.
  11. Before installation to moisten a sealing ring of a protective flange with fuel.
  12. Position of installation of a protective flange: the arrow on a flange should be opposite to a mark in a fuel tank.
