Second Hand Alfa Romeo 155 Fuel Injection Pump

The Alfa Romeo 155 was produced from 1992 to 1998 as a single generation, with a facelift arriving in 1995 that brought interior and exterior changes but did not fundamentally alter the engine lineup. Whether a pump from a pre-1995 car crosses to a post-1995 car depends on whether the engine codes match exactly, so name the boundary confidently but route the swap itself to your breaker: confirm with them against your registration whether ancillary or mounting changes at the 1995 facelift affect your specific application. The engine code, found on your V5 or via a VIN check, is the single most useful detail you can supply.

No — the Twin Spark and the earlier single-spark engines carry different engine codes and use different fuelling and injection systems, so the pumps are not interchangeable between them. Trim level and badge do not affect fitment here; what matters entirely is the engine code, which will confirm which injection setup your car left the factory with. Always quote your engine code to the breaker so they can match the correct pump rather than relying on model year alone.

Almost certainly not — the 1.8 and 2.0 petrol engines in the 155 range carry distinct engine codes and are calibrated for different fuel delivery requirements, so their injection pumps are unlikely to be interchangeable. Engine capacity alone is a useful guide, but the engine code is the definitive reference; check your V5 or run a VIN check to confirm exactly which unit is fitted. Give that code to the breaker and they can verify compatibility rather than working from displacement alone.

The 155 TD used a turbodiesel engine, and fitment of a used injection pump depends first on the engine code matching precisely, then on confirming fuel type (diesel only, never mix with petrol-engine parts). Year within the generation matters too, as mid-production running changes can affect ancillary and mounting details — confirm with the breaker against your registration whether the specific pump they hold suits your exact build date. The engine code from your V5 or a VIN check is the most reliable detail to give them.

Trim level does not affect which fuel injection pump your 155 needs; fitment is determined entirely by the engine code, not by whether the car is a base, Super, or Cloverleaf model. A Cloverleaf will carry a higher-specification engine with its own engine code, but it is that code driving the pump choice, not the Cloverleaf badge itself. You may find cosmetic or interior differences between a parts car and your own depending on trim, but those have no bearing on pump compatibility.

Only if the engine codes are identical — Alfa Romeo used some engines across multiple models, and if a 156 or another Alfa shares the exact same engine code as your 155, the pump may be compatible in principle. However, ancillary fitment and any ECU pairing or immobiliser coding differences between models introduce real uncertainty that goes beyond engine code matching alone, so this must be confirmed with the breaker against your specific registration. Do not assume cross-model compatibility without that verification.
