OEM Part Number: confirm via VIN — fuel pumps (aftermarket) Hüco 133543 / Astemo 2503543
| Fuel pumps / feed units (aftermarket) | Astemo 2503543 (complete feed unit / tank module with sender, diesel, assembly notes apply); Hüco 133543 (complete feed unit / tank module with sender, diesel, assembly notes apply); Hüco 133047 (bare electric in-tank pump, petrol); Hella 8TF 358 304-031 (feed unit / sender assembly, 5-pin, with sender, supplied with seal, fuel type not stated); Ridex 1382F0193 (feed unit with in-tank pump and sender, 5-pin, 12 V, 3 bar, 130 l/h and 80 l/h dual output); ERA 770162A (bare in-tank pump, 3.2 bar, 120 l/h, 2-pin, 38 mm diameter, repair kit 770162 also offered); Magneti Marelli 313011300142 (bare supply pump insert, 3 bar, 115 l/h, 12 V); Ridex 458F0040 (bare in-tank pump, 3.4 bar, 100 l/h, 2-pin, mounting kit included). |
|---|---|
| Types & variants | The 1.7 and 2.0 CRDi diesels use a tank-mounted feed unit with level sender only (Astemo and Hüco modules, diesel-labelled); the 1.6 GDi, 1.6 T-GDi and 2.0 petrols use an in-tank electric pump, listed as a bare pump (Hüco 133047) or as part of a sender assembly (Hella, Ridex 1382F0193). Several 3 bar, 95-130 l/h bare pump inserts are listed without fuel or engine assignment. |
| Genuine (OE) numbers quoted | Kamoka 8410005 quotes OE 8450008680; Kamoka 8410007 quotes OE 311110M000; none quoted on the Bosch-group, Hüco, Astemo, Hella or ERA items. |
| Fitment notes | Diesel Tucsons have no in-tank pressure pump of their own, so a feed-unit replacement is a sender module rather than a pump, and the two diesel modules carry assembly instructions that must be followed. On petrol cars a bare insert such as Hüco 133047 or ERA 770162A can be fitted into the original housing, leaving the level sender in place; the Hella and Ridex 5-pin assemblies replace the sender as well, so the gauge calibration should be checked after fitting. |
A Genuinely Important Habit Worth Building: Checking for Open Recalls — Hyundai Tucson Fuel Pump
Hyundai has issued multiple genuine, confirmed fuel pump recalls across various models and years, including issues with both the low-pressure in-tank pump and, on some turbocharged models, the high-pressure pump connection not being properly torqued during assembly — creating a genuine fuel leak and fire risk in the affected cases. It's genuinely worth checking your specific VIN against Hyundai's official recall checker directly, particularly on a used car where you can't be certain a previous owner had any relevant recall work completed.
It's also worth knowing the documented symptoms worth watching for: engine hesitation or a "bucking" feeling during acceleration, noticeably longer crank times when starting, and difficulty accelerating under load such as merging or climbing hills — worth having these looked at promptly if you notice them, rather than waiting for a complete failure.
Hyundai Tucson Fuel Pump: A Part That Fails at the Worst Possible Moments
On the Hyundai Tucson, this particular failure has a knack for terrible timing, stranding drivers mid-journey instead of giving fair warning while the car's parked up safely. Spotting the early signs early enough is what stands between a routine fix and a roadside breakdown.

Hyundai Tucson Fuel Pump: What It Does
Getting fuel from tank to engine at the correct combustion pressure is down to the fuel pump, and on the Hyundai Tucson that pump sits inside the tank, submerged in fuel. That location is exactly why swapping out such a small part is rarely a quick job.
Hyundai Tucson Fuel Pump: Generations & Engines: Fuel Pump Type
| JM (2004–2010), all petrol (2.0/2.7 V6) & diesel | Spans both diesel (in-tank lift pump plus an engine-mounted high-pressure pump) and petrol (in-tank low-pressure pump, plus a separate high-pressure pump if direct-injection) variants — confirm your exact engine before ordering |
|---|---|
| LM/ix35 (2009/2010–2015), all petrol & diesel | Spans both diesel (in-tank lift pump plus an engine-mounted high-pressure pump) and petrol (in-tank low-pressure pump, plus a separate high-pressure pump if direct-injection) variants — confirm your exact engine before ordering |
| TL (2015–2020), all petrol & diesel (incl. N Line trim) | Spans both diesel (in-tank lift pump plus an engine-mounted high-pressure pump) and petrol (in-tank low-pressure pump, plus a separate high-pressure pump if direct-injection) variants — confirm your exact engine before ordering |
| NX4 (2020–present), all petrol, diesel & hybrid/PHEV (incl. N Line) | Spans both diesel (in-tank lift pump plus an engine-mounted high-pressure pump) and petrol (in-tank low-pressure pump, plus a separate high-pressure pump if direct-injection) variants — confirm your exact engine before ordering — the hybrid system doesn't change this; the combustion engine still needs its own fuel pump |
