Subaru Impreza Fuel Pump: A Part That Fails at the Worst Possible Moments
On the Subaru Impreza, 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.
Subaru Impreza 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 Subaru Impreza 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.

Confirmed: A Genuine, Widespread Safety Recall Worth Checking Your Car Against — Subaru Impreza Fuel Pump
This is genuinely worth checking directly on your specific car: Denso-manufactured low-pressure fuel pumps have been recalled across nearly 200,000 vehicles spanning multiple Subaru models, including 2018-2020 model year Imprezas, addressing an impeller defect that can cause the fuel pump to fail and the engine to stall while driving. A related, separate confirmed UK recall also covers certain Foresters for the same underlying issue. It's genuinely worth checking your VIN against the official recall register directly.
It's also genuinely worth knowing that a class-action settlement in relation to this issue has provided an extended warranty specifically covering the fuel pump, reportedly up to 15 years or 150,000 miles on affected vehicles — worth asking a dealer directly whether this extended coverage applies to your specific car.
