Repair Sharan/Sharan Volkswagen>> System of injection of fuel of the VR6 engine>> Electric fuel pump>> Removal and installation of the fuel pump
The fuel pump fastens in the peculiar way and its removal needs a special key of VW 3217. If it is, the pump can be removed together with an internal part of the soaking-up case.

At electrogasoline pump removal the fuel tank should be filled no more, than on 2/3.

At removal of the fuel pump fuel can flow out a little. Pairs of fuel are poisonous and inflammable, therefore it is necessary to provide good airing of a workplace.

Removal of the fuel pump carry out in the following order:
- 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

- disconnect from the pump a four-contact shtekerny block 11 (fig. 206) of the fuel level sensor 30 of the fuel pump 31;
- disconnect submitting and returnable 9th pipelines from a flange 12;
- by means of a special key of VW 3217 remove a flange 12. If the special tool is not present, unscrew a plastic nut on which there are small edges, by means of a screw-driver (it is better stupid) easily striking on it;
- take from an opening of a fuel tank a flange 12 and a sealing ring 14;

From the bottom party of a flange two are attached топливопровода: bringing 13 (it is designated by a letter "V") and returnable (retsirkulyatsionny) 15 (is designated by the letter "R").

- turn to the left the fuel pump, deducing it from bayonetny fastening, and take out it.
Installation of the fuel pump carry out to sequences of return to removal, carrying out the following recommendations:
- at installation of the pump do not deform a fuel level sensor float in a tank;
- at installation of a flange pay attention to its situation. On it there is an arrow who after installation should be on one line with a stamped arrow in a tank;
- moisten with gasoline a sealing ring of the 14th flange before assembly;
- check durability of landing of submitting and returnable pipelines. Fix them spring collars.
