Product Description
On some Subaru Impreza models, fuel can move away from the pump during hard cornering when running below half a tank, causing the pump to draw in air and briefly cut fuel supply to the engine.
Subaru addressed this on the Impreza STi Spec C with a redesigned fuel pump assembly. A revised housing helps keep the pump’s sock submerged in fuel, supporting a steadier fuel supply during spirited driving.
This listing shows fitment across several Impreza generations, including 1992-2000 (GC/GF), 2001-2002 (GD/GG Bugeye), 2003-2005 (GD/GG Blobeye) and 2006-2007 (GD/GG Hawkeye).
