Opel Corsa B 1993–2000 Service and Repair Manual: General information and precautions

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. On 1.4 and 1.6 litre models, the pump supplies fuel to throttle body unit which incorporates the fuel injection valve and pressure regulator. On 1.8 and 2.0 litre models, 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.

On all models a fuel filter is incorporated in the feed line from the pump to the fuel rail to ensure the fuel supplied to the injectors is clean.

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, when disconnecting any fuel line, depressurise the fuel system.
