Mazda 3 Fuel Tank Ring

Choose a Mazda 3 fuel tank retaining ring

Browse Mazda 3 fuel tank rings at Parts Factory Australia. Match the vehicle series, build details and fuel-pump mounting arrangement before selecting a replacement retainer.

Check the listed application

The linked locking-ring listing identifies Mazda 3 BK applications between 2003–2008 and reference 579-204. Review its full engine and body-style fitment before ordering. See the Mazda 3 ring product listing for current availability and supplied components.

Compare the original ring and tank opening

Match the original reference, diameter, engagement profile and pump or sender flange. Similar appearance does not prove that a ring will secure the assembly correctly. Have the installation requirements and condition of the sealing surfaces checked.

Mazda 3 fuel tank ring FAQs

Is a sealing gasket included with the Mazda ring?

The selected ring listing does not establish that a separate seal is included. Confirm the required gasket and supplied components before purchase.

Is a retaining ring the same as a sealing O-ring?

No. The ring retains the assembly; the specified seal sits at the sealing interface. Follow the vehicle-specific service procedure and do not assume a new ring alone will resolve a leak.
