Cheap Vauxhall Cavalier Fuel Tank

The Cavalier Mk2 ran from 1981 to 1988 and the Mk3 from 1988 to 1995, and these are completely different platforms, so a fuel tank from a Mk2 will not cross over to a Mk3. Tank mounting points, dimensions, and fuel-line connections differ between generations. Always confirm the exact generation with your breaker before ordering.

Both years fall within the Mk3 generation (1988–1995), so there is a realistic chance of compatibility, particularly if the engine code and fuel type match. That said, ancillary details such as sender unit position, strap mounts, or filler-neck routing can change quietly during a production run, so confirm the specific part number against your registration with the breaker before buying.

Trim level — whether GL, GLS, CD, or GSi — does not determine which fuel tank fits; what matters is the engine code, fuel type (petrol or diesel), and year within the generation. A breaker may supply a tank from a different trim to yours and it should be mechanically equivalent, though minor cosmetic differences in mounting brackets or straps are possible. Always quote your engine code and registration to the breaker so they can verify the correct unit.

The most important detail is your engine code, which you can find on your V5C or via a VIN check, as mechanical parts like the fuel tank follow the engine code above everything else. You should also confirm the model year and whether the car is petrol or diesel, as these affect fuel system configuration. Supply your registration to the breaker and they can cross-reference the correct tank for your specific build.

This is not recommended — diesel and petrol fuel tanks can differ in capacity, filler-neck diameter, and sender-unit arrangement, and mixing them risks fuel system problems. Always match the fuel type exactly when sourcing a used tank. Tell your breaker clearly whether your car is petrol or diesel, and provide your engine code to make sure the right unit is quoted.

The Mk3 Cavalier received a facelift in 1992, and while the fundamental platform carried over, fitment of specific components like the fuel tank across that facelift boundary is not something that can be confirmed as fact without checking. Name the facelift year and your registration when speaking to a breaker, and ask them to verify the part against both the pre- and post-facelift build before committing to a purchase.
