The fuel level sensor includes a float and a potentiometer. With fall of level of fuel the float falls, thus a potentiometer connected with a float, increases electric resistance of the sensor. Therefore tension falls, and the arrow of the index of level of fuel moves in the leer direction (is empty).

Fig. 206. The details of a power supply system located near a fuel tank: 1 — a cover of a fuel tank; 2 — a sealing ring; 3 — a safety ring; 4 — rubber consolidation; 5 — the return valve; 6 — an O-shaped sealing ring; 7 — the ventilating valve; 8 — the reduktsionny valve; 9 — the returnable pipeline; 10 — a cap nut; 11 — a shtekerny block, black color, the pump and the sensor of amount of fuel; 12 — a flange; 13 — a bringing fuel hose; 14 — a sealing ring; 15 — a returnable hose; 16 — the return valve; 17 — a bolt, 10 N · m; 18 — a jellied branch pipe; 19 — the ventilating pipeline; 20 — a sealing ring; 21 — a safety ring; 22 — the ventilating pipeline; 23 — bolts, 25 N · m; 24 — a fuel tank; 25 — fastening of a fuel tank; 26 — bolts, 20 N · m; 27 — the cover/holder of the fuel filter; 28 — топливопровод (black color); 29 — the fuel filter (observe the direction of movement of fuel); 30 — the fuel level sensor in a tank; 31 — the fuel pump; 32 — the mesh filter

Sensor 30 removal (see fig. 206 ) level of fuel is carried out as well as removal of the fuel pump until the flange 12 will be removed. Then a hand pull out from a fuel tank the sensor, having pressed its lock latch.

At installation of a flange pay attention to correctness of its arrangement.
