Second Hand Mazda RX-8 Fuel Tank

The RX-8 was produced as a single generation running from 2003 to 2012, with a facelift introduced in 2008, so a 2004 and a 2006 tank are both pre-facelift cars and are strong candidates to interchange. The key detail to cross-reference is the engine code, which on the RX-8 is the 13B-MSP Renesis rotary across the range, but confirm with the breaker against both registrations that no ancillary or mounting changes occurred between those years. Never assume fitment without the breaker verifying against your specific VIN.

The RX-8 facelift arrived in 2008, so a 2007 car is pre-facelift and a 2009 is post-facelift, meaning you are asking about a part crossing a known production boundary. While the rotary engine code remained the 13B-MSP Renesis throughout, fuel tank mounting points and ancillary connections can change at a facelift, so you must confirm compatibility with the breaker against both registrations rather than assuming it will swap straight over. Treat the 2008 facelift as a hard boundary until the breaker has verified the part numbers match.

Trim level does not affect fuel tank fitment on the RX-8; the R3, PZ, and standard variants all shared the same 13B-MSP Renesis rotary engine and the tank specification follows the engine and model year, not the trim badge. You may find cosmetic or minor equipment differences between cars you are looking at for donor parts, but these have no bearing on whether the tank itself will fit. Focus on the engine code and production year rather than the trim name when describing your requirements to the breaker.

The single most useful piece of information is the engine code from your V5C or a VIN check — on the RX-8 this is the 13B-MSP Renesis rotary, but confirming it from your paperwork removes any doubt. You should also provide the model year and whether your car is pre-facelift (2003–2007) or post-facelift (2008–2012), as ancillary and mounting details may differ across that boundary. Your full registration or VIN lets the breaker cross-reference the part number and flag any mid-production changes you might not be aware of.

The RX-8 was petrol-only in the UK, so fuel type is not a variable here, but the gearbox type — six-speed manual or four-speed automatic — is worth mentioning to the breaker as it can influence ancillary components associated with the fuel and emissions system. The core tank is likely shared, but confirm with the breaker against your registration that no associated components differ between manual and automatic cars before purchasing. Giving the breaker your engine code alongside the gearbox type keeps the query as precise as possible.
