9 Disconnect the battery negative lead.

10 Chock the front wheels, then jack up the rear of the vehicle and support on axle stands.

(see УJacking and Vehicle SupportФ).

11 Clean the area around the pump mounting, and position a suitable container under the pump.

12 Using a hose clamping tool or self-locking pliers, clamp the fuel tank-to pump hose to prevent excessive petrol spillage, or alternatively make arrangements to collect the contents of the fuel tank which will otherwise be released. Disconnect the hose from the pump.

13 Disconnect the fuel outlet hose from the pump and plug the hose to prevent petrol spillage.

Caution: Petrol under pressure may spray out of the outlet as the hose is disconnected.

14 Disconnect the wiring plug from the pump.

15 Slacken the clamping bolt, and slide the pump from the bracket assembly.

16 Refitting is a reversal of removal, but make sure that the rubber sleeve is correctly located around the pump body in the bracket, and ensure that the fuel hoses are securely connected. If the hoses were originally secured with crimped type clips, discard these and use new worm drive clips.

2.0 litre DOHC models
17 On these models the fuel pump is mounted in the fuel tank, on the same mounting as the fuel level sender unit (see illustration).
