Parts for your 2014 Subaru Impreza-Fuel pump

2014 Subaru Impreza fuel pump — what it does and how to look after it

Based on Subaru’s factory service manual for the 2012–2016 Impreza (FB20) in the Fuel Injection section, and the Subaru Electronic Parts Catalogue for MY2014, this model is fitted with an in‑tank electric fuel pump module located beneath the rear seat access panel. So yes, a fuel pump is relevant and used on the 2014 Subaru Impreza.

The fuel pump’s job is straightforward but critical: it draws petrol from the tank and delivers it at steady pressure to the Impreza’s multi‑point injectors. On the FB20 engine it’s a returnless, in‑tank setup with an integrated strainer and fuel level sender, and it’s managed by the ECU via a control module to keep pressure stable during cold starts, overtaking and long climbs. When it’s healthy, starts are crisp, throttle response feels clean, and the car runs smoothly on 91–98 RON petrol, including E10 where applicable.

There’s no scheduled replacement interval for the pump on this model. The filter/strainer is part of the in‑tank module and isn’t a routine service item. Sensible habits go a long way: avoid frequently driving on near‑empty, as the pump relies on fuel for cooling
