Second Hand Vauxhall Insignia Fuel Tank

The Insignia ran in two distinct generations: the Mk1 from 2008 to 2017 (with a facelift in 2013) and the Mk2 (also known as the Grand Sport/Sports Tourer) from 2017 onwards. Fuel tanks are generally generation-specific, so a Mk1 tank is very unlikely to suit a Mk2 and vice versa. Always confirm the generation with your breaker before ordering.

Both years sit within the Mk1 generation, but 2013 is the facelift year, which means your 2012 car is pre-facelift and your 2015 is post-facelift. The tank itself may physically interchange, but ancillary fittings, sender unit connections, and mounting points can vary across that boundary. Name the exact engine code from your V5 when asking breakers, and ask them to confirm fitment against your registration rather than the year alone.

Yes — fuel type matters directly, as a diesel tank and a petrol tank are not interchangeable due to differences in the filler neck, pump housing, and vent systems. Beyond that, your engine code (found on your V5 or via a VIN check) is the single most useful detail you can give a breaker, as mechanical specifications including tank configuration follow the engine code more reliably than the model year alone. Always quote your engine code when requesting a quote.

For the fuel tank itself, trim level — whether that's SE, SRi, Elite, or Design — does not affect fitment; the tank is determined by engine, fuel type, and generation, not the badge on the bootlid. You may find cosmetic or ancillary differences on the donor car (such as condition or attached brackets), but the trim name alone should not drive your search. Focus on matching the engine code and fuel type, and let your breaker confirm against your registration.

Gearbox type can occasionally influence fuel tank shape or capacity on some vehicles where the tank is designed around drivetrain tunnel packaging, so it is worth flagging whether your car is manual or automatic when speaking to a breaker. The engine code and fuel type remain the primary fitment factors, but confirming gearbox type as well gives the breaker the full picture. Never assume a direct swap without the breaker checking your specific registration.

The Sports Tourer (estate) and the hatchback/saloon body styles can differ in underfloor packaging, which may mean the fuel tank shape or mounting differs between them. This is a case where body style genuinely could matter, unlike trim level, so you should tell the breaker which body style your car is as well as the engine code and fuel type. Confirm fitment against your registration with the breaker rather than assuming tanks are shared across body styles.
