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 throttle body assembly (which incorporates the single fuel injector and the fuel pressure regulator), as well as the Electronic Control Unit (ECU) and the various sensors, electrical components and related wiring. The air cleaner contains a disposable paper filter element and incorporates a flap valve air temperature control system, which allows cold air from the outside of the car and air warmed by the exhaust manifold, to enter the air cleaner in the correct proportions.

Refer to Section 7 for further information on the operation of each relevant fuel injection system and to Section 18 for information on the exhaust system. Throughout this Chapter, 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 8.
