Second Hand Fiat Fullback Fuel Injection Pump

The engine code is the most important detail when matching a fuel injection pump — it tells the breaker exactly which pump variant was fitted, far more reliably than the year or trim level alone. You'll find the engine code on your V5C or by running a VIN check. Always quote this to the breaker when requesting a quote, as even cars from the same year can have different engine variants. Without it, fitment cannot be confirmed.

The Fiat Fullback was sold in the UK from 2016 and received a facelift in 2018, so a pump from a pre-facelift truck crossing into a post-facelift one spans a known production boundary. If the engine code is identical on both vehicles, compatibility is more likely, but ancillary and mounting changes can occur across a facelift and must be confirmed with the breaker against your registration. Give the breaker both the donor vehicle's engine code and your own registration to let them cross-reference accurately. Never assume fitment across that 2018 boundary without that check.

No, the trim level does not affect fuel injection pump fitment on the Fiat Fullback — this is a mechanical part that follows the engine code, not the badge or specification level. A pump from a base-spec truck will be mechanically the same as one from a higher trim, provided the engine codes match. You may notice cosmetic differences on a part pulled from a different trim, such as bracket finishes, but these don't affect function. Confirm the engine code matches and let the breaker do the rest.

The Fiat Fullback is mechanically related to the Mitsubishi L200 and shares powertrain components, so there is a reasonable chance of parts interchanging if the engine codes match exactly — both use the 4N15 diesel engine in the UK market. However, ECU pairing and immobiliser coding are areas you must confirm with the breaker against your registration, as a pump that is physically identical may still require coding to your vehicle. Quote both VINs and engine codes when requesting quotes to give the breaker the best chance of advising correctly. Do not assume direct swap without that confirmation.

Gearbox type is a relevant factor when matching a fuel injection pump, as differences in fuelling and engine management calibration can exist between automatic and manual variants even with the same engine code. It is safest to source a pump from a truck with the same gearbox type as yours. Confirm this with the breaker when requesting a quote, quoting your engine code and gearbox type together. Mixing gearbox types on this part is not something Findapart or breakers can guarantee will work without further investigation.

ECU pairing and immobiliser coding are not something that can be confirmed from part numbers or engine codes alone — this is an area you must raise directly with the breaker and ideally with a diesel specialist or auto electrician before purchasing. A pump that is a correct mechanical match may still require programming or coding to communicate properly with your vehicle's ECU. Always ask the breaker whether the pump they are supplying has any known coding requirements before committing. This step could save you a costly return or a failed repair.
