ATTENTION At any installation works with a fuel tank observe the following instructions. (For example fuel, an absorber with absorbent carbon, vacuum hoses), and also electric wires it is necessary to lay lines of all types how they were laid initially. Check durability of fastening of a wire of weight between a mouth of a fuel tank and a body for protection against the electrostatic category. Provide free space for all mobile and hot components.

Security measures at work in a power supply system

With a view of safety before depressurization of a power supply system it is necessary to remove safety locks 13 and 14 from a block of safety locks as the fuel pump can be involved at operation of the contact switch of a driver's door.

Safety locks 13 and 14 are in a block of safety locks in the switching block, in the left part of a water taking away box.

At removal and installation of the fuel level sensor or the fuel pump (the module of supply of fuel) from the full or partially filled fuel tanks it is necessary to consider:

ATTENTION Toplivoprovod is under pressure. to avoid traumas and hit on skin, put on goggles and gloves. Before separation of hoses wrap up a junction rags. Then dump pressure, accurately weakening connection.

Before the beginning of works near an assembly opening of a fuel tank follows establish an exhaust hose of the included installation of an extract of OG. If exhaust installation for removal of OG is absent, it is possible to apply the centrifugal fan (the engine should settle down away from an air stream) with productivity of 15 m3 / h.
