Hyundai i40 Fuel Pump Replacement Parts

Yes, all Hyundai i40 variants sold in the UK have a fuel pump — both the 1.6 and 2.0 petrol engines and the 1.7 CRDi diesel engine require one to deliver fuel from the tank to the engine. However, the diesel 1.7 CRDi uses a high-pressure injection system that also involves a separate high-pressure fuel pump on the engine itself, so it is worth clarifying with the breaker which pump you need — the in-tank lift pump or the high-pressure pump. If you are searching for a fuel pump for an i40, it does exist and is a genuine fitment across the range.

The Hyundai i40 was produced as a single generation from 2011, with a facelift arriving in 2015, so a 2012 and a 2015 car sit either side of that facelift boundary. Engine codes are the most important factor here — if both cars share the same engine code (found on your V5 or via a VIN check), there is a reasonable chance of compatibility, but whether the fuel pump assembly or sender unit changed at the 2015 facelift is something you should confirm with the breaker against your specific registration before buying.

Trim level does not affect fuel pump fitment on the i40 — the pump is determined by engine code and fuel type, not by whether the car is a Style, SE, Premium, or Sport variant. You may find cosmetic differences between stripped donor cars and higher-spec ones, but the fuel pump itself is a mechanical part tied to the engine, not the trim. Just confirm your engine code and fuel type (petrol or diesel) with the breaker and trim level can be ignored entirely.

These are different engines with different engine codes, and the in-tank fuel pump assemblies are unlikely to be interchangeable between them even though both are petrol units. Always quote your engine code — not just the engine size — when getting a quote from a breaker, as this is the most reliable way to ensure the part is from a like-for-like donor vehicle. A breaker can cross-reference the part number against your registration to confirm compatibility before you commit.

Yes, the 1.7 CRDi diesel i40 uses a fundamentally different fuelling system to the petrol variants, and the pumps are not interchangeable across fuel types. Diesels have both an in-tank lift pump and a high-pressure pump driven off the engine, so make sure you tell the breaker exactly which one you need and quote your engine code (D4FD is the common code for the 1.7 CRDi) to help them locate the right part. Used diesel fuel pumps can be available from breakers but supply depends on stock, so getting quotes from multiple dismantlers on Findapart is a sensible approach.

The in-tank fuel pump on the i40 is a mechanical and electrical component that does not typically require ECU coding in the way that some other parts do, and many owners do fit these as a DIY job. However, whether any immobiliser or ECU pairing is involved with the fuel pump on your specific car is something you should confirm with the breaker against your registration, as this can vary and is not something we can state as fact. If you are unsure about the fitting process, a qualified mechanic will be able to advise based on your exact vehicle.
