Shop fuel system parts for the Subaru WRX (all generations — Impreza-based GC/GF/GM, GD/GG and GE/GH/GV/GR, plus standalone VA and VB). This collection spans every WRX generation in the research: Impreza-based cars on GC/GF/GM, GD/GG and GE/GH/GV/GR chassis (sold in the US from 2002) and the standalone VA (2015–2021) and VB (2022–present) cars, all with turbocharged flat-four engines — EJ20 / EJ205 2.0-liter, EJ255 2.5-liter, FA20DIT / FA20F 2.0-liter and FA24F / FA24DIT 2.4-liter, varying by generation and market — and Symmetrical All-Wheel Drive throughout. Fuel systems split by era: EJ generations use port injection, while FA WRX generations use direct injection only, so fuel-system advice flips by generation. You will find fuel pumps, injectors, rails, lines and flex-fuel kits here — every part in this collection is fitment-tagged for the Subaru WRX, so check your trim, year and engine against the product fitment notes before ordering.

Frequently Asked Questions

What fuel system parts fit my Subaru WRX (all generations — Impreza-based GC/GF/GM, GD/GG and GE/GH/GV/GR, plus standalone VA and VB)?
Every fuel system part in this collection is fitment-tagged for the Subaru WRX. The split is by era: port injection on EJ generations versus direct injection only on FA generations, so start with your engine and confirm fitment on the product page before ordering.

How does WRX fuel-system advice change by generation?
It flips by era. EJ generations use port injection, while FA WRX generations use direct injection only, so fuel-system parts and carbon-maintenance advice are not the same across the line. Identify whether your car is an EJ or an FA car before choosing fuel-system parts.
