Cheap Peugeot 307 Fuel Pump

The 307 ran from 2001 to 2008, with a facelift in 2005, so a 2003 and a 2006 car sit either side of that boundary. Fitment depends primarily on the engine code rather than the year alone, so two cars sharing the same engine code are far more likely to be compatible than two cars of different years that happen to carry the same badge. Confirm with the breaker against both registrations before buying, as ancillary details can change across a facelift.

The 307 was sold with several different diesel engines — including 1.4 HDi, 1.6 HDi, and 2.0 HDi variants — and each has its own high-pressure fuel pump that is not interchangeable between engine families. The engine code, which you can find on your V5 or via a VIN check, is the single most useful detail to give a breaker when sourcing a replacement. Never assume a diesel pump will swap across engine codes even if the car looks identical from the outside.

Yes, absolutely — petrol and diesel fuel systems are completely different, and the pumps are not interchangeable under any circumstances. Petrol 307s use a low-pressure in-tank pump to feed fuel to the injectors, while diesel variants use a high-pressure pump as part of the common-rail or indirect injection system. Always confirm fuel type and engine code with the breaker to make sure you are getting the correct unit.

Trim level — whether S, SE, or XSi — does not affect which fuel pump the 307 needs, as the pump follows the engine, not the trim grade. What actually matters is your engine code and fuel type, both of which can be confirmed from your V5 or a VIN check. Give the breaker your registration alongside the engine code and they will be able to match the correct pump regardless of trim.

Body style does not determine which fuel pump a 307 requires — the pump is dictated by the engine code and fuel type. A 307 SW and a 307 hatchback sharing the same engine code will use the same pump. Confirm the engine code with the breaker and they can cross-reference fitment from either body style without issue.

Whether a used fuel pump requires any ECU pairing or immobiliser coding after fitting is something you should confirm directly with the breaker or a Peugeot specialist against your specific registration, as this can vary and is not something that can be stated as fact here. It is worth raising the question before purchasing so you understand any additional work that may be involved. A breaker familiar with 307 parts will often have useful practical experience on this point.
