2. Lift up the rear seat cushion and remove the access cover from the floor to reveal the pump.

3. Disconnect the electrical connectors from the pump.

4. Bearing in mind the information, slacken the retaining clip and disconnect the fuel hose. Plug the hose end to minimise fuel loss.

Fuel pump, damper and filter assembly

7. Clamp the fuel hoses on either side of the pump to prevent loss of fuel when they are disconnected. Self-locking grips are useful for this. Disconnect the hoses, bearing in mind the information given.

8. Unscrew the pump mounting clamp bolts and withdraw the pump from its flexible insulator. Disconnect the electrical plug as the pump is withdrawn.

9. Alternatively, the pump can be removed complete with filter and damper diaphragm unit if the mounting strap nuts are unscrewed and the assembly removed from its flexible mountings.

Refitting
