Hyundai Tucson Fuel Injection Pump Replacement Parts

The third-generation Tucson (Mk3) ran from 2015 to 2021 with a facelift in 2018, so a 2016 and a 2019 car sit either side of that facelift boundary — they share the same generation but the facelift brought changes that may affect ancillary and mounting details on the injection pump. The safest starting point is to match the engine code exactly, which you'll find on your V5C or via a VIN check, and then confirm with the breaker whether the pre-facelift pump crosses to the post-facelift car against your registration. Engine code, fuel type, and gearbox type are the details that matter most here, not the model year alone.

The second-generation Tucson (Mk2) ran from 2009 to 2015 and the third-generation (Mk3) from 2015 to 2021, and these are distinct platforms with different engine families, so a straight swap across that generation boundary is very unlikely. Engine codes changed between the two generations, and a fuel injection pump follows the engine code above everything else. Run a VIN check to confirm your engine code and pass that to the breaker — they can tell you definitively whether any overlap exists.

No — different diesel engine displacements use different injection pumps and the engine code will be different, so a pump from a 1.7 diesel will not be a direct fit for a 2.0 diesel regardless of model year or trim. Always match on engine code first; the code stamped on the engine or listed on your V5C is the single most useful detail you can give a breaker when sourcing this part. Fuel type and exact engine code must both match.

No — trim level does not affect fuel injection pump fitment on the Hyundai Tucson. Whether your car is an entry-level S or a higher-spec Premium or Premium SE, the pump is determined entirely by the engine code, fuel type, and gearbox type. You may receive a pump pulled from a different trim with different cosmetic surroundings, but the mechanical part itself is what counts, and trim has no bearing on that.

This is an important question but one we can't answer as a blanket fact, because whether a used injection pump requires ECU pairing or immobiliser coding depends on the specific system fitted to your car and the year of production. You should raise this directly with the breaker quoting you the part, and factor in the potential cost of coding with a Hyundai specialist or auto-electrician before committing to the purchase. Don't assume a used pump will be plug-and-play without confirming this first.

Gearbox type is one of the factors that can affect injection pump calibration and compatibility, so even with a matching engine code you should not assume a pump from a manual car is a straight fit for an automatic. Pass your full engine code, fuel type, and gearbox type to the breaker and ask them to confirm compatibility against your registration rather than relying on the engine code alone. This is especially worth clarifying on diesel models where fuelling maps can differ between transmission types.
