3 Working inside the luggage compartment, depress the filler housing retaining tangs, and push the assembly out through the body panel. Recover the gasket.

4 Immerse the housing assembly in a container of hot water for approximately ten minutes, then prise the hinge cover from the housing, and using a screwdriver, prise the filler flap hinge legs out of the sockets in the housing.

Refitting
5 Commence refitting by warming the filler flap and housing, as during removal, then push the flap hinge legs into the housing.

6 Further refitting is a reversal of removal, ensuring that the housing gasket and retaining tangs are correctly located.
