Mercedes-Benz Citan Fuel Tank Replacement Parts

The first-generation Citan ran from 2012 through to around 2021, so a 2013 and a 2015 are within the same generation and the fuel tank is likely to be compatible provided the engine code and fuel type match. The engine code is the most reliable guide here — check your V5 or run a VIN check and supply that code to the breaker. Ancillary fittings and mounting brackets can change quietly mid-production, so always confirm the specific part number with the breaker against your registration before buying.

The Citan received a mid-life update around 2016-2017, and while the core tank shape may be shared across the generation, mounting points and sender unit connections can differ across that boundary. Name the boundary to the breaker — tell them whether your van is pre- or post-2016 — and confirm fitment against your registration rather than assuming the tank drops straight in. Matching engine codes and fuel type (diesel or petrol) on both vehicles remains the most important starting point.

No — trim level has no bearing on fuel tank fitment for the Citan; whether you have a base Worker or a higher-spec Tourer, the tank is determined by engine code, fuel type, and gearbox type rather than trim. You may find cosmetic differences around the filler neck area or protective covers between variants, but the structural tank itself follows the drivetrain specification. Give the breaker your engine code and fuel type and ignore the trim badge when searching.

No, diesel and petrol fuel tanks are not interchangeable: the filler neck diameter, vapour recovery system, and sometimes the tank geometry differ between the two fuel types. Always source a tank that matches your exact fuel type, and confirm the engine code with the breaker so they can verify the correct specification. Fitting the wrong fuel-type tank is a safety risk, so this is one area where there is no grey zone.

Engine code matters more than year for the Citan because Mercedes-Benz offered different engine options across the range and tank specifications can follow the drivetrain rather than the model year. Two Citans from the same year but with different engines could require different tanks, so supplying your engine code — found on your V5 or via a VIN check — gives the breaker the most accurate information to match the part. Year is a useful secondary filter, but on its own it is not a reliable enough guide to guarantee fitment.

Gearbox type is one of the fitment factors to consider, as the tank position or shape can sometimes be influenced by the transmission tunnel in vans with different gearbox configurations. This is one to route directly to the breaker — give them your engine code, fuel type, and confirm whether your van is manual or automatic so they can cross-reference against their stock. Never assume a straight swap without the breaker verifying the specific part against your registration.
