OEM Part Number: confirm via VIN — fuel pumps (aftermarket) Delphi FE0670-12B1 / Magneti Marelli 313011300038

Accuracy note: Covers the Lexus NX (2014-2021) 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)	Delphi FE0670-12B1 (bare in-tank pump, petrol, metal housing); Magneti Marelli 313011300038 (bare in-tank pump, 3 bar / 90 l/h, 12 V); ERA 770171A (bare in-tank pump, 4 bar / 140 l/h, 2 connectors, 52 mm body, 9 mm outlet); ERA 770161A (bare in-tank pump, 3 bar / 110 l/h, 2 connectors); ERA 770162A (bare in-tank pump, 3.2 bar / 120 l/h, 2 connectors); Ridex 458F0040 (bare in-tank pump, 3.4 bar / 100 l/h, 2 connectors); Meat & Doria 76416 (bare in-tank pump, 3 bar / 95 l/h).
Types & variants	Bare in-tank pumps only, no complete module with sender. The 200t 2.0 turbo direct-injection engine needs a higher-flow pump than the 300h hybrid, which is where the 4 bar / 140 l/h ERA 770171A fits against the 3 bar / 90-110 l/h units for the hybrid. No diesel NX exists, so the diesel-marked Delphi FE0695-12B1 does not apply.
Genuine (OE) numbers quoted	3111137300 (Meat & Doria 76385 / Hoffer 7506385); 8450008680 (Kamoka 8410005); 170429F500 (Meat & Doria 76416 / Hoffer 7506416); 142504 (Kamoka 8410016). None are Lexus numbers.
Fitment notes	Petrol and hybrid only. The bare pump drops into the original Toyota/Denso housing with the existing sender retained; the gauge sender is not sold separately in this range. Match by engine, since the turbo and hybrid pumps differ in flow.

Lexus NX Fuel Pump: A Part That Fails at the Worst Possible Moments

On the Lexus NX, there's rarely a convenient time for this to fail — it tends to strike mid-journey rather than while the car's sitting safely on the drive. Knowing what the early symptoms look like buys valuable time to get ahead of it.

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.

Lexus NX Fuel Pump: What It Does

The job here is simple in principle — draw fuel from the tank, deliver it to the engine at the right pressure — but the Lexus NX's fuel pump sits submerged inside the tank, which makes physical access for replacement far more involved than the small part itself implies.

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.

All generations, petrol, hybrid & PHEV	Petrol: typically a single in-tank low-pressure pump; some later or higher-output variants may add a separate engine-mounted high-pressure pump for direct injection — confirm your exact engine — the hybrid system doesn't change this; the combustion engine still needs its own fuel pump

Confirmed: A Genuine, Widespread Safety Recall Worth Checking Your Car Against — Lexus NX Fuel Pump

This is genuinely worth checking directly: a confirmed recall covers a fuel pump defect affecting millions of vehicles globally across the Toyota and Lexus range, including this model, caused by an internal impeller made from a resin material that can degrade or deform under certain operating conditions. If this happens, the pump can stop working entirely, which can cause the engine to stall while driving and genuinely increase the risk of a crash. It's genuinely worth checking your specific VIN against the official recall register directly — the repair is a free fuel pump assembly replacement carried out by an authorised dealer.

A genuinely useful set of symptoms worth knowing before a pump fails completely: documented warning signs include the engine turning over for several seconds before starting or failing to start at all, sputtering or hesitation particularly at consistent highway speeds, and a whining noise from the rear of the car near the fuel tank.

It's also genuinely worth knowing that Lexus has a separate, confirmed UK recall history relating to fuel pump wiring specifically on certain earlier models, where expansion and contraction of the fuel tank could stretch the pump's electrical harness, causing a break in the circuit that stops the fuel pump and engine without warning.
