Cheap Peugeot 408 Fuel Tank

The Peugeot 408 was introduced in the UK in 2022 as a second-generation model, built on the EMP2 platform, with the first facelift not yet firmly established in the UK market at the time of writing. For fuel tank fitment, the engine code is the most important detail rather than the model year alone, so always have your engine code to hand from your V5 or a VIN check before approaching a breaker. If you are unsure which production phase your car falls into, confirm the exact specification with the breaker against your registration.

The 408 launched in 2022 and any mid-production changes to tank mounting points or ancillary fittings across that 2022–2024 window are not always well documented, so you cannot assume all tanks within that range are a straight swap. Your engine code is the most reliable starting point, and you should confirm with the breaker against your registration whether the specific tank they have matches your build date and specification. Never guarantee fitment based on year alone.

Yes, fuel type matters significantly here. The 408 was offered with petrol and plug-in hybrid (PHEV) powertrains, and PHEV variants have a smaller or differently configured fuel tank to accommodate the hybrid system, so a petrol-only tank and a PHEV tank are not interchangeable. Always tell the breaker your exact fuel type and engine code so they can match the correct tank to your car.

Trim level does not affect fuel tank fitment on the 408; whether your car is a GT, Allure, or Allure Premium, the tank is determined by the drivetrain and engine code, not the badge. You may find minor cosmetic differences in surrounding trim panels or underbody covers between specifications, but the tank itself should be common across trims sharing the same engine and fuel type. Confirm the engine code with the breaker and disregard the trim name when sourcing this part.

On PHEV models the fuel system can interact with engine management and hybrid control systems, and whether a replacement used tank requires any module pairing or sensor configuration is something you must confirm with the breaker and your fitting garage rather than assume. Bring your registration and engine code to the breaker so they can advise on what comes with the tank. Never assume a used tank is a plug-and-play fit without checking this with a qualified technician.

The single most useful detail you can supply to a breaker is your engine code, which you can find on your V5 logbook or via a VIN check, and you should also confirm your fuel type (petrol or PHEV) and gearbox type. Body style and trim level do not affect which tank you need, so focus the conversation with the breaker on those mechanical details. Always confirm fitment against your exact registration before purchasing, as mid-production changes to ancillary fittings or mounting points may not be publicly documented.
