Second Hand BMW M8 Fuel Tank

The BMW M8 (F91/F92/F93) was produced from 2019 onwards, with a mid-cycle update arriving for the 2022 model year; this is the boundary to be aware of when sourcing a used fuel tank. For a mechanical component like the fuel tank, the engine code from your V5 or a VIN check is the most reliable guide, as it confirms exactly which specification your car was built to. Whether a tank from a pre-2022 car crosses cleanly to a post-2022 car is something you should confirm with the breaker against your registration, as mounting and ancillary details can change at a facelift without being widely documented.

2019 and 2022 M8s both use the S63 4.4-litre twin-turbo V8, so the core engine specification is consistent across that boundary, which is a good starting point. However, 2022 marks the mid-cycle update for the F92/F91/F93 generation, and ancillary details such as tank mounting points, sender unit connections, or fuel pump housings can quietly change at a facelift even when the drivetrain stays the same. You should confirm cross-year fitment directly with the breaker against your exact registration rather than assume like-for-like interchange.

The M8 was offered in three body styles — Coupe (F92), Convertible (F91), and Gran Coupe (F93) — and the fuel tank can differ between these body styles because the floor and underbody packaging are not identical across them. When contacting a breaker, confirm which body style the donor car is, as well as the engine code, to avoid ordering a tank with the wrong shape or filler neck position. Never assume a Coupe tank will drop straight into a Gran Coupe or Convertible without checking with the breaker against your registration.

The M8 and M8 Competition are trim levels rather than different mechanical platforms — both use the same S63 4.4-litre twin-turbo V8 engine code, and trim level alone does not affect fuel tank fitment. A tank from a standard M8 and an M8 Competition of the same body style and year should be mechanically equivalent, so do not pay a premium purely on the basis of the Competition badge. Confirm the engine code, body style, and year with the breaker as normal, and the trim name itself can be disregarded for this component.

The single most useful detail is your engine code, which will be on your V5C or can be confirmed via a VIN check — for the M8 this should be the S63 unit, but quoting the exact code removes all ambiguity. Also tell the breaker your model year, body style (Coupe, Convertible, or Gran Coupe), and whether your car is pre- or post-2022 facelift, as these factors can affect tank shape and ancillary connections. Trim level and colour are irrelevant for this part and can be left out.

The standard 8 Series (G14/G15/G16) shares its generation with the M8 but uses different engines — petrols such as the B58 straight-six or N63 V8 — and the fuel system components are not necessarily identical to those paired with the M8's S63 unit. Differences in fuel pump requirements, sender unit wiring, and underbody packaging mean a straight swap from a non-M 8 Series cannot be assumed. Always cross-reference the engine code with the breaker and confirm fitment against your registration before purchasing.
