Alfa Romeo 156 Fuel Injection Pump Replacement Parts

The Alfa Romeo 156 ran from 1997 to 2007, with a facelift in 2003 that brought some mechanical and electrical changes, so a pump crossing that 2003 boundary may or may not interchange directly — confirm with the breaker against both registrations. What matters most is that the engine code on both cars matches exactly, as the pump is built around the engine specification, not the model year alone. Your engine code is shown on your V5C or can be found via a VIN check, and supplying it to the breaker is the single most useful thing you can do.

The Selespeed is a robotised single-clutch gearbox variant, and while the gearbox type itself does not directly determine which fuel injection pump is fitted, the two cars must share the same engine code for the pump to be a candidate for interchange. Trim and gearbox designation do not affect pump fitment — the engine code is what the pump follows. Check that the engine codes match and confirm compatibility with the breaker before purchasing.

No, the trim level — whether Lusso, Progression, TI, or any other — does not affect which fuel injection pump your 156 needs, as this is a mechanical part that follows the engine, not the badge or equipment level. What you should focus on is matching the engine code, fuel type (diesel or petrol), and confirming the pump came from a car with the same specification. Expect cosmetic differences between trim levels on breaker cars, but ignore those entirely when assessing pump fitment.

The 2003 facelift is a known production boundary for the Alfa Romeo 156, and while the engine families carried across it, there were engineering changes during this period that could affect ancillary components and their mounting. Whether a pump from a pre-2003 car will interchange directly with your post-2003 car is something you should confirm with the breaker against both registrations rather than assume. Give the breaker your engine code and registration, and ask them to check the donor car's details against yours before committing.

No — diesel and petrol fuel injection pumps are entirely different in design, function, and fitment, and the two are not interchangeable under any circumstances. The diesel 156 used JTD engines while petrol variants used a range of Twin Spark units, and the pump must match your fuel type exactly. Always confirm the fuel type and engine code with the breaker to make sure you are being quoted the correct part.

The most important detail is your engine code, which you can find on your V5C logbook or by running a VIN check — this tells the breaker exactly which pump specification your car needs, far more reliably than the year or trim level alone. You should also confirm your fuel type (diesel or petrol) and your registration so the breaker can cross-reference their stock. Be aware that ECU pairing and any immobiliser coding requirements are worth raising directly with the breaker, as these can vary and are not something to assume about without checking.
