Used Mazda 6 Fuel Injection Pump

The Mazda 6 ran as the GH generation from 2008 to 2012, with the GJ generation starting from 2013, so a 2010 and a 2013 are from entirely different generations with different engines and fuel systems. A pump from the GH generation is very unlikely to suit a GJ car, but the engine code is the definitive check — supply your V5 engine code and the breaker can confirm whether anything overlaps. Never assume fitment across that 2012–2013 generation boundary without the breaker verifying it against both registrations.

Yes — body style makes no difference to fuel injection pump fitment on the Mazda 6; the pump follows the engine, not the shape of the car. A saloon and an estate sharing the same engine code and fuel type will use the same pump. Always confirm the engine code from your V5 rather than relying on body style when ordering.

Trim level — whether SE, Sport, Sport Nav, or any other Mazda 6 grade — has no bearing on fuel injection pump fitment whatsoever. The pump is determined by the engine code, fuel type, and year within the generation, not by which trim the car left the factory with. Match the engine code on your V5 and you can disregard trim entirely, though do expect cosmetic differences between donor and your car that have no effect on the part itself.

Both years sit within the GJ generation (2013 onwards), so there is a reasonable basis for compatibility if the engine codes match, but there were running production changes across this generation that could affect ancillary fittings or mounting details. Get the engine code from your V5 and ask the breaker to check both registrations before buying, as only they can confirm whether a mid-production change affects the specific pump you need.

No — petrol and diesel fuel injection systems are fundamentally different in design and operation, and the two are not interchangeable under any circumstances. Always specify your fuel type alongside the engine code when requesting a quote from a breaker. Fitting the wrong type of pump would cause serious engine damage, so this is one compatibility point that must be confirmed before any purchase.

The GJ Mazda 6 received a facelift in 2015, and while the generation runs continuously from 2013, there can be differences in engine specification and ancillary components across that facelift boundary. The engine code on your V5 is the starting point, but whether a pre-2015 pump crosses cleanly to a post-2015 car — or vice versa — is something you should confirm with the breaker against both registrations rather than assume. Name the facelift year and your exact engine code when contacting a breaker and they can advise properly.
