- disconnect the plug «–» from AB;
- unscrew for short time a stopper of a bulk mouth to dump pressure in system;
- remove a rug on the right side under the second row of seats, unscrew bolts of fastening and remove the electrogasoline pump and fuel level sensor hatch;

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
