Used Peugeot 407 Fuel Tank

The Peugeot 407 ran as a single generation from 2004 to 2011, with a facelift arriving in 2008, so a 2005 tank and a 2008 tank sit either side of that facelift boundary. Whether the tank itself changed at that point is something you should confirm with the breaker against your exact registration, as ancillary fittings and sender unit positions can vary mid-production. Give the breaker your engine code from your V5 and they can cross-reference properly before supplying the part.

Yes, fuel type is one of the most important things to get right — a petrol tank and a diesel tank are not interchangeable, and fitting the wrong one is a serious safety and mechanical concern. Always tell the breaker whether your 407 is petrol or diesel, and ideally supply your engine code from your V5 or a VIN check so they can match the correct unit. Never assume a tank from a different fuel type will do even as a temporary fix.

Trim level does not affect fuel tank fitment on the 407 — the SE, Executive, and GT all use the same tank for a given engine and fuel type. You may find cosmetic or minor ancillary differences between cars depending on spec, but the tank itself follows the engine code and fuel type, not the badge on the boot. Focus on matching engine code, fuel type, and year range rather than worrying about trim.

The 407 facelift arrived in 2008, and while the core tank design may be shared, whether the fittings, sender unit, and mounting points are identical across that boundary is not something we can state as fact. Route this question to the breaker and give them both the year of the donor car and your own registration, along with your engine code, so they can check compatibility before dispatch. Crossing a facelift boundary always warrants that extra check.

The single most useful thing you can supply is your engine code, which you'll find on your V5 registration document or via a VIN check — this tells the breaker far more than the year or trim level alone. You should also confirm whether your car is petrol or diesel, your gearbox type, and the year of your car. With those details the breaker can match the correct tank and flag any known fitting differences before you buy.

Body style can sometimes affect tank shape or capacity, so it is worth mentioning to the breaker whether your car is a saloon or estate when requesting a quote. However, the primary matching criteria remain the engine code, fuel type, and year — confirm with the breaker whether the body style makes a difference for your specific engine and year combination. Do not assume a tank from one body style will drop straight in to the other without that confirmation.
