Alfa Romeo 159 Fuel Injection Pump Replacement Parts

The Alfa Romeo 159 ran as a single generation from 2005 to 2011 with no major facelift that split the range into distinct mechanical generations, so a 2006 and a 2010 car can share the same pump — but only if they share the same engine code. The engine code is the critical factor here, not the year, so check your V5 or run a VIN check to confirm your code before ordering. Always verify the specific part numbers with the breaker against your registration to be certain.

Trim level — including Lusso — has no effect on fuel injection pump fitment; what matters is the engine code, fuel type, and gearbox type, not the trim badge. The Sportwagon is a different body style to the saloon, but the injection pump follows the engine, not the bodywork, so a matching engine code is what you need to confirm. Check your engine code on the V5 and give it to the breaker so they can pull the right unit.

The engine code is the single most important detail for this part — it tells the breaker exactly which pump was fitted and ensures the fuel delivery characteristics, fixings, and connections are correct for your car. You'll find the engine code on your V5 logbook or through a VIN check, and it's worth quoting it to the breaker upfront rather than relying on year and fuel type alone. Diesel variants in particular had several different engines across the 159 range, so the code matters more than anything else.

No — petrol and diesel fuel injection pumps are completely different in design, pressure ratings, and function, and they are not interchangeable under any circumstances. Always confirm your fuel type alongside the engine code when requesting a quote from a breaker. Fitting the wrong pump type would cause serious engine damage, so this is one point where there is no flexibility.

In most cases the injection pump itself is matched to the engine rather than the gearbox, but some diesel high-pressure pump variants can differ depending on whether the car has a manual or automatic transmission due to fuelling and calibration differences. It's safest to tell the breaker both your engine code and your gearbox type when asking for a quote, so they can confirm compatibility. Do not assume a manual and automatic 159 with the same engine code will always take an identical pump without the breaker checking first.

Ti is a trim designation and has no bearing on the fuel injection pump fitted; the pump is determined entirely by your engine code, fuel type, and gearbox type. Give the breaker your engine code from the V5 rather than the trim name and they'll be able to match the correct unit. Trim differences on the 159 are cosmetic and equipment-related, so they won't lead you to a different pump.
