PUMP SUPPLY

The fuel filter is placed in the fuel feeding circuit after the fuel pump and can be found

under the body of the vehicle close  to the tank.
    The filter element is made of paper, with 0,01mm porosity and has the very important
function to retain the eventual impurities and stop them to reach  the pressure regulator
and injector.

ATTENTION:

 The fuel filter is provided at the exit with a very fine metallic cloth which can retain

possible filtering paper particles from it; Therefore upon mounting, attention must be
paid at the arrow marked on the fuel filter body, which shows the flow direction of the
fuel.

The filter is to be changed at maximum 20 000 km.

ANTIPOLLUTION

The cycling circuit of the fuel vapours has as purpose the reduction of the environment

pollution with gasoline vapours, and is composed of:

1

. Fuel tank, tight

2

. Active carbon can

3

. Carbon can purging valve

4

. Fresh air intake

The gasoline vapours are absorbed from the tank (1) in the can (2) with active carbon

grains and arriving then at the purging valve (3). The electric valve opening is done by the
electronic control unit ( pin 29) in certain operation conditions of the engine.

Check this circuit as far as its sealing is concerned, its valve operation as well as the

free cycling of the vapours between the fuel tank and the carbon can.

Take into consideration, when valve mounting, the flow direction of the gasoline vapours,

which must be according to the arrow marked on its body, from the  can to  the inlet manifold.

D

ISMO UNTING

Remove the can from its fixing support by pulling up.
Dismount the fixing ring clips of the hoses to the can and disconnect the hoses.

R

EMO UNTING

Perform in reverse order the dismounting operations.

ATTENTION:

Take into consideration when mounting, about the hoses connection direction (the

gasoline vapour cycling is from the duct to the carbon can purge valve). Use good ring
clips,which must be well tightened.
