OEM Part Number: confirm via VIN — fuel pumps (aftermarket) Hüco 133305 / Delphi FE0670-12B1
| Fuel pumps / feed units (aftermarket) | Hüco 133305 (bare in-tank pump, petrol, 3 bar, assembly information must be observed); 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 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, mounting kit); Meat & Doria 76416 (bare in-tank pump, 3 bar / 95 l/h). |
|---|---|
| Types & variants | All listings are bare electric in-tank pumps without a sender; no complete IS III feed unit is offered. The IS 300h hybrid and the 2.0 turbo 200t share the same bare-pump approach, while the 250 and 350 V6 with D-4S direct injection run a higher-pressure in-tank supply, so flow and pressure must be checked against the engine. There is no diesel IS III, and the Delphi FE0695-12B1 shown as diesel is not applicable. |
| Genuine (OE) numbers quoted | 170429F500 (Meat & Doria 76416 / Hoffer 7506416); 3111137300 (Hoffer 7506385 / Meat & Doria 76385); 142504 (Kamoka 8410016); 8450008680 (Kamoka 8410005). No Lexus numbers are quoted. |
| Fitment notes | Petrol only. The bare pump is fitted into the original Lexus module, reusing the sender, float arm and swirl pot. The Hüco 133305 is the only reference that names the application as petrol and carries fitting instructions; the rest are generic by size, so compare body diameter, length and outlet with the old pump before ordering. |
Lexus IS Fuel Pump: A Part That Fails at the Worst Possible Moments
On the Lexus IS, 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.
Lexus IS 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 IS's fuel pump sits submerged inside the tank, which makes physical access for replacement far more involved than the small part itself implies.
Lexus IS Fuel Pump: Generations & Engines: Fuel Pump Type
| All generations, petrol & hybrid | 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, Specific Safety Recall Worth Checking Your Car Against — Lexus IS Fuel Pump
This is genuinely worth checking directly, particularly on a 2022 model: a confirmed recall specifically named 856 examples of the 2022 IS, produced between May 2021 and February 2022, as part of a wider fuel delivery recall covering 9,139 vehicles across several Lexus models. The recalled component is the internal impeller within the low-pressure fuel pump, made from a resin material that can degrade under certain conditions, potentially causing the pump to fail entirely and the engine to stall while driving. 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.
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.
