Volkswagen Passat Fuel Tank Replacement Parts

The Passat moved from the B8 generation (2015–2023) so both years sit within the same generation, which is a good starting point for compatibility. However, confirm with the breaker against your registration, as ancillary fittings, sender unit connections, and mounting points can vary within a production run. The engine code from your V5 is the most useful detail to give them.

The B7 (2010–2014) and B8 (2015–2023) are distinct generations built on different platforms, so a direct swap across that boundary is unlikely to work without modification. Name this boundary clearly to the breaker and confirm against your registration before purchasing, as tank shape, capacity, and mounting points differ between generations. Never assume a cross-generation tank will fit without verification.

Fuel type can affect tank design, filler neck configuration, and associated components such as the fuel pump and sender unit, so a diesel tank and a petrol tank from the same generation are not necessarily interchangeable. Always tell the breaker both your fuel type and your engine code from the V5, as these are the most critical details for matching a used fuel tank correctly.

Trim level does not affect fuel tank fitment on the Passat — S, SE, SE Business, and R-Line all share the same mechanical underpinnings for the fuel system within a given engine and generation. You may find cosmetic differences in ancillary parts sourced from higher trims, but the tank itself is not trim-specific. Focus on matching the engine code, fuel type, and generation rather than the trim badge.

The Passat has been offered in both saloon and estate (Variant) body styles within each generation, and tank shape or capacity can differ between them due to differing underbody layouts. Confirm with the breaker against your exact registration to make sure the tank from a donor vehicle matches your body style as well as your engine code and fuel type.

The single most important detail is your engine code, found on your V5 registration document or via a VIN check, as mechanical parts follow the engine code above all else. You should also have your fuel type, gearbox type (manual or automatic), and registration year to hand, as these help the breaker narrow down the correct tank within the right generation. Confirm any ancillary fittings and mounting brackets directly with the breaker against your registration before committing to a purchase.
