OEM Part Number: confirm via VIN — fuel pumps (aftermarket) Hella 8TF 358 106-691 / Delphi FE0351-12B1

Accuracy note: Covers the Kia Rio (2017-) as listed in the UK aftermarket catalogues. In-tank fuel pumps are sold two ways: as a complete feed unit (the pump in its swirl pot with the fuel-level sender and float) or as a bare pump that is fitted into the old housing, and petrol and diesel versions are not interchangeable — most diesels have only a low-pressure lift pump in the tank, with the high-pressure pump on the engine. The references below are UK aftermarket catalogue listings for this generation, labelled by brand; genuine numbers are shown only where a listing quotes one. Check fuel type, the plug pin count and whether your car has one sender or two (saddle tanks on 4x4 and some larger cars) against your VIN before ordering.

Fuel pumps / feed units (aftermarket)	Hella 8TF 358 106-691 (complete in-tank feed unit with fuel sender and fine filter, 4 pins); Delphi FE0351-12B1 (bare in-tank petrol pump, 113 x 38 mm, metal housing, no seal); Delphi FE0735-12B1 (bare in-tank pump, 112.8 x 38 mm, no pressure sensor, no seal); Magneti Marelli 313011303157 (in-tank module, 3 bar operating, 3.5 bar max, 100 l/h); ERA 770162A (in-tank pump, 3.2 bar / 120 l/h, 2 connectors, 38 mm diameter, repair kit 770162 offered); Ridex 458F0040 (in-tank feed unit, 3.4 bar / 100 l/h, 2 connectors, mounting material included); Ridex 1382F0381 (complete fuel supply module, 12 V).
Types & variants	The Hella unit and the Ridex 1382F0381 are complete modules; the Hella is the only one stated to include the level sender. Everything else is a bare 38 mm petrol cartridge at 3 to 3.8 bar for the 1.0 T-GDI, 1.25 and 1.4 MPI engines. No diesel lift pump is listed for the 1.4 CRDi.
Genuine (OE) numbers quoted	170429F500 (Hoffer 7506416, Meat & Doria 76416); 8450008680 (Kamoka 8410005). The JPN 20M0512-JPN and Oyodo 20M0512-OYO share the number 20M0512 but it is not quoted as an OE reference.
Fitment notes	For a complete swap with a fresh gauge sender the Hella feed unit is the one to use; a bare Delphi or ERA cartridge goes into the original housing only if the diameter, ports and plug match, and the old sender and float are reused.

A Genuinely Important Habit Worth Building: Checking for Open Recalls — Kia Rio Fuel Pump

Kia has issued multiple genuine, confirmed fuel pump and fuel pipe recalls across its larger models, including a follow-up recall covering cars that had an engine replaced under an earlier bearing recall, where the high-pressure fuel pipe connection may have been damaged or improperly torqued during that repair work. It's genuinely worth checking your specific VIN against Kia'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.

A genuinely useful, real diagnostic pattern worth knowing: documented cases involving a fuel pipe connection leak on related Kia models describe occasional hesitation beforehand that's easy to dismiss as nothing significant, before a sudden, complete failure — the engine sputtering, multiple warning lights appearing at once, and the car entering limp mode.

It's also worth knowing that Kia has, in some cases, extended fuel pump warranty coverage considerably beyond a car's original term on specific affected engines — worth checking directly with a dealer whether any extended coverage applies to your specific model.

Kia Rio Fuel Pump: A Part That Fails at the Worst Possible Moments

Rather than failing conveniently while parked, this component on the Kia Rio tends to give up mid-journey, which is about the worst possible moment. Learning to recognise the early symptoms is the best defence against being caught out.

Before you buy: fuel pump specifications vary by engine size and fuel type, and petrol/diesel versions are never interchangeable. Always confirm against your VIN before ordering.

Kia Rio Fuel Pump: What It Does

The Kia Rio's fuel pump function — pulling fuel from the tank and pressurising it for the engine — is straightforward, but its usual location isn't: it sits submerged inside the tank itself, which is precisely why access for replacement is more work than the part's size suggests.

Accuracy note: these are documented patterns by generation and engine family, not a substitute for confirming your exact engine code — always verify against your V5C before ordering, since petrol and diesel pumps are never interchangeable.
