Parts for your 2008 Subaru Impreza-Fuel pump

2008 Subaru Impreza Fuel Pump

Yes, a fuel pump is relevant and fitted to the 2008 Subaru Impreza. Subaru’s 2008MY Impreza/WRX factory service manual and the Subaru parts catalogue list an in-tank electric fuel pump module (combined with the fuel level sender and filter/regulator) across petrol variants. Subaru’s technical information system describes the system as multi-point fuel injection supplied by an in-tank electric pump, confirming its use on GE/GH/GR chassis cars.

On the 2008 Impreza, the fuel pump’s job is straightforward but vital: draw petrol from the tank and maintain stable pressure at the injectors so the engine starts cleanly, idles smoothly, and pulls strongly. Because it’s submerged in the tank, the pump runs cooler and quieter, and the module design helps control fuel slosh on hills and during quick cornering—handy on Aussie and Kiwi back roads.

As part of regular servicing, the pump isn’t a scheduled replacement item, but a few habits go a long way. Avoid running the tank near empty—fuel cools and lubricates the pump. Stick to quality fuel and keep an eye out for contamination after any suspect fill. If the car shows hard starting, hesitation on climbs, flat spots under load, or an audible high-pitched whine from the tank area, it’s time for checks.

• Common signs: longer cranking, lean fault codes, loss of power at highway speeds, surging, misfire under load, or a noisy pump.
• Basic checks: fuel pressure test to the spec in the Subaru service manual, current draw test at the pump circuit, and inspection of the in-tank strainer.

Replacement on a 2008 Impreza is relatively workshop-friendly thanks to a service access panel under the rear seat. A competent home mechanic can do it with care, but fuel safety is critical. Depressurise the system, disconnect the battery, work in a well-ventilated area away from sparks, and have a fire extinguisher handy. Replace the tank seal/O-ring and lock ring if worn, keep the module clean during removal, and verify no leaks on reassembly. When upgrading or replacing, stick with OEM-quality parts to maintain correct pressure and flow, especially on turbo WRX models.

Popular questions

Does the 2008 Subaru Impreza have a fuel pump and where is it located?
Yes. All 2008 petrol Impreza models use an in-tank electric fuel pump. It sits inside a combined pump/level-sender module beneath an access panel under the rear seat cushion. That design keeps the pump cool and makes servicing more straightforward than dropping the tank.

How long does the fuel pump last on a 2008 Impreza?
It’s common to see 10+ years and well over 200,000 km from the original pump if the car is well maintained. Running the tank very low, contaminated fuel, or a clogged strainer can shorten its life. If the car develops hard starting, surging, or power loss on hills, have fuel pressure checked against Subaru specs before it strands you.

Can the fuel filter be replaced separately on this model?
The primary filter is integrated into the in-tank module and is generally treated as non-serviceable by Subaru
