Mercedes-Benz SLK Fuel Pump Replacement Parts

The Mercedes-Benz SLK R170 generation ran from 1996 to 2004, so both years fall within the same generation, which is a good starting point. However, fitment depends primarily on the engine code — a pump from an SLK 200 Kompressor will not suit an SLK 320 even within the same generation, so match by engine code first. Confirm the exact interchange with the breaker against your registration before purchasing.

The R170 ran from 1996 to 2004 and the R171 from 2004 to 2011 — these are distinct generations with different engine families, so a straight swap is very unlikely to be correct. Engine codes, fuel delivery pressures, and pump mounting arrangements can all differ between generations. Always confirm cross-generation compatibility with the breaker against your registration number.

Trim level and badge alone do not determine fuel pump fitment — what matters is the engine code, fuel type (petrol or diesel), and where applicable whether the engine is supercharged or naturally aspirated. An SLK 200 Kompressor and an SLK 350 have entirely different engines, so they will require different pumps — but that difference is down to the engine, not the trim designation itself. Supply your engine code (found on your V5 or via a VIN check) to the breaker for an accurate match.

Yes — all petrol-engined SLK variants across the R170, R171, and R172 generations use an electric fuel pump, typically located in or on the fuel tank, to supply fuel to the injection system. The SLK was never offered with a diesel engine in the UK, so all standard variants have this component. If you have been told your vehicle has no fuel pump, it is worth double-checking you are not being confused with a high-pressure pump fitted additionally on direct-injection engines — confirm the specific pump type you need with the breaker.

Both years fall within the R172 generation, which ran from 2011 to 2016, so they share the same basic platform, which is encouraging. Fitment still depends on the engine code — for example, an SLK 200 and an SLK 250 use different engines — so match by engine code rather than year alone. Confirm the exact part compatibility with the breaker against your registration before buying.

The R171 received a facelift around 2008, but the core engine codes and fuel delivery systems were carried over rather than replaced at that point. In most cases the fuel pump itself is determined by engine code and fuel system type, not by whether the car is pre- or post-facelift. That said, ancillary or mounting changes mid-production are something you should confirm with the breaker against your registration, as these details can vary in ways that are not always publicly documented.
