About part number KBB3424CX

A fuel filler flap housing supports the outer fuel door and secures the locking actuator on the body panel. Located on the rear, right-hand side of the vehicle, this unit houses the filler neck access area and connects to the central locking system. When the unit is working correctly, the fuel flap sits flush with the surrounding bodywork, opens smoothly when released, and locks securely when the vehicle is locked.

To ensure this component is correct for your vehicle, you must match the part number directly. The primary manufacturer part number for this item is KBB3424CX, and associated numbers found on the part include KBB3424C1 and KBB3424D1. You can usually find these numbers stamped or moulded into the plastic housing on the rear or underside of the casing. Matching these exact numbers is what decides if the part will fit.

These housings are commonly replaced after accidental damage, hinge failure, or when the internal locking actuator stops responding. When fitting a replacement housing, you may also need new plastic mounting clips or fixings, and you may need to transfer the outer painted flap cover from your original unit.

  • Specification: manufacturer Mazda; colour Black; intended use Replacement Part.

About this kind of part: fuel filler flaps

A fuel filler flap is the small painted door over the filler neck, with its hinge and usually a spring or a damper behind it. On an electric or a hybrid car the same part covers the charging socket and is often larger and electrically released. It is painted to match the body, which is why it is replaced far more often than it fails: the flap sits where people lean, and it is one of the few painted parts a careless hand touches every week.

Why people replace one

  • The flap has been creased or dented, usually by being pushed shut against the filler cap or by a knock at a pump.
  • The hinge has broken or the spring has failed, so the flap no longer stays shut or no longer stays open.
  • The paint has faded or the lacquer has lifted, which shows badly because the flap sits in the middle of a large flat panel.
  • The release mechanism or the electric actuator has failed and the flap no longer opens from inside the car.
  • A rear quarter panel has been repaired and the original flap was damaged in the process.

Fitting it

  • Most flaps unbolt from the hinge inside the filler recess, sometimes with the hinge as one assembly and sometimes as a separate part.
  • On a car with an electric release, the actuator and its loom stay with the car and the flap comes off on its own.
  • The seal or the foam around the recess is worth checking at the same time, because it is what stops water collecting in the bottom of it.
  • A flap is supplied in primer or in the colour it was sprayed when new, and a matching finish needs the paint code from the car's own identification plate.

Making sure it is the right one

  • Match the part number. A petrol or diesel flap and a charging flap for the same model are different parts, and so are the versions before and after a facelift.
  • Check whether yours comes with the hinge. Some models sell the flap alone and some sell it as an assembly, and the hinge is often the part that broke.
  • Compare the curvature against your own panel. A flap is pressed to the shape of one body line and will not sit flush in another.
  • Treat a painted used flap as a starting point for colour rather than a match, because it has aged with the car it came off.

What to look for in the photographs

A Part number — Stamped or on a label on the inner face, often under the hinge.
B Hinge — Whether the hinge is included and whether it is straight. A bent hinge is why most flaps no longer sit flush.
C Spring or damper — The mechanism that holds the flap open or shut. It is often what has failed, and it is sometimes a separate part.
D Inner face — The back of the flap, where water sits and where corrosion starts on a steel one.
E Outer surface — Look across the face at a shallow angle. A crease or a dent in a flat panel this small is invisible in a straight-on photograph.
