General information and precautions (Peugeot 106)

The fuel system consists of a fuel tank mounted under the rear of the car (with an electric fuel pump immersed in it), a fuel filter, fuel feed and return lines. The fuel pump supplies fuel to the fuel rail, which acts as a reservoir for the four fuel injectors which inject fuel into the inlet tracts. A fuel filter is incorporated in the feed line from the pump to the fuel rail, to ensure that the fuel supplied to the injectors is clean.

Refer to Section 6 for further information on the operation of the relevant fuel injection system and Section 17 for information on the exhaust system. Throughout this Section, it is occasionally necessary to identify vehicles by their engine codes rather than engine capacity. Refer to Chapter 2A for further information on engine code identification.

Warning: Many of the procedures in this Chapter require the removal of fuel lines and connections, which may result in some fuel spillage. Before carrying out any operation on the fuel system, refer to the precautions given in "Safety first!" at the beginning of this manual and follow them implicitly. Petrol is a highly-dangerous and volatile liquid and the precautions necessary when handling it cannot be overstressed.

Note: Residual pressure will remain in the fuel lines long after the vehicle was last used. Before disconnecting any fuel line, depressurise the fuel system as described in Section 7.
