Second Hand Ford Fusion Fuel Injection Pump

The Ford Fusion was sold in the UK as a single generation from 2002 to 2012, with a facelift arriving around 2005, so there is one broad family to work within. Whether a pump from a pre-facelift car (2002–2005) will cross over to a post-facelift car (2005–2012) depends on whether the engine code and fuel system specification remained unchanged across that boundary, and you should confirm this with the breaker against your exact registration rather than assume it will swap straight over. The engine code, found on your V5C or via a VIN check, is the detail the breaker needs above all else.

The engine code is the single most important piece of information — it tells the breaker exactly which pump specification your car left the factory with, far more reliably than the year or badge alone. You will also want to confirm the fuel type (diesel pumps and any petrol direct-injection pumps are not interchangeable) and your gearbox type, as these can influence the pump variant used. Dig the engine code out of your V5C or run a VIN check before contacting any breaker.

Trim level does not affect which Fuel Injection Pump you need — LX, Zetec, and Ghia are specification packages covering interior and cosmetic features, not the engine or fuel system. What matters is that the engine code, fuel type, and gearbox type match between the donor car and yours. Bear in mind a pump pulled from a different trim car may look slightly different in terms of brackets or ancillary mounting, so confirm any ancillary or mounting details with the breaker against your registration.

A 2004 Fusion is pre-facelift and a 2007 is post-facelift (the facelift came around 2005), so you are crossing a known production boundary, which means you cannot assume the pump will interchange without checking. Provide the breaker with both engine codes and your registration so they can verify whether the pump specification changed across that boundary. Never assume year-to-year compatibility on its own — the engine code is what the breaker will work from.

TDCi and TDdi are different diesel fuel system architectures — the TDDi uses a distributor-type injection pump while the TDCi uses a common-rail system — so these pumps are not interchangeable. Always make sure the engine code on the donor car matches yours exactly, not just the broad diesel badge. Confirm the full engine code with the breaker before agreeing to any purchase.

Whether a used Fuel Injection Pump requires ECU pairing or immobiliser coding to your specific vehicle is something you must confirm with the breaker and a qualified auto-electrician rather than assume either way. Some diesel pump and ECU combinations are paired at manufacture, and fitting an uncoded unit can cause a no-start condition. Make sure you raise this question before you buy so you can factor in any additional work and cost.
