Used Hyundai i30 Fuel Tank

Both years fall within the second-generation i30 (Mk2, 2012–2017), so they share the same basic platform, but Hyundai made running production changes and the 2014 facelift introduced some updates that could affect ancillary fittings, sender unit positions, or mounting points. The core tank shape may well be compatible, but you should confirm the exact fit with the breaker by providing both registration numbers so they can cross-reference part numbers. Never assume fitment across a facelift boundary without that check.

No — the first-generation i30 (Mk1, 2007–2012) and the second-generation i30 (Mk2, 2012–2017) are built on different platforms with different underbody dimensions, so the fuel tanks are not interchangeable. Always stay within the same generation when sourcing a used tank. Confirm the exact part number with the breaker against your registration to be sure.

Yes, fuel type matters — a diesel i30 and a petrol i30 can have differently specified tanks or sender unit arrangements, so always tell the breaker whether your car is petrol or diesel. The engine code (found on your V5 logbook or via a VIN check) is the single most useful detail you can supply, as mechanical parts follow the engine specification rather than the badge or trim level. Providing both your registration and the engine code gives the breaker the best chance of finding you a confirmed match.

No — trim level does not affect fuel tank fitment on the i30; the tank is determined by the platform, generation, and fuel type, not by whether the car is a Classic, Active, Style, or SR. You may find cosmetic differences in the engine bay or surrounding components depending on trim, but the tank itself is not trim-specific. Focus on matching generation, fuel type, and engine code rather than trim name.

The third-generation i30 (Mk3, 2017–present) uses a new platform and is not the same as the outgoing Mk2 (2012–2017), so crossing that generation boundary is a significant risk and the tanks are very unlikely to be directly interchangeable. You should source a tank confirmed as Mk3 and provide your full registration and engine code to the breaker so they can verify the correct part. Do not assume compatibility just because the model years are close together.

Body style can influence tank shape and capacity, so a tank from a Tourer estate may not be the same as one from a hatchback even within the same generation. Always tell the breaker your exact body style alongside your registration and engine code, rather than assuming all i30 variants share an identical tank. The breaker can cross-reference part numbers to confirm the right unit for your specific car.
