When you think about the soul of your Subaru WRX STI, you probably think of turbocharged power, razor-sharp handling, and a car that begs to be pushed to the limit. But beneath all that excitement lies a crucial system that makes it all possible: your fuel delivery. Without a reliable, properly functioning gas tank and fuel cell assembly, your 2004 WRX STI can’t perform at its peak—or worse, it won’t run at all. That’s where the 04 WRX STI GAS TANK FUEL CELL ASSEMBLY OEM comes in, designed to deliver factory-level fitment, efficiency, and dependability.
This OEM assembly is not just a replacement part—it’s the foundation for consistent performance. Whether you’re restoring your 2004 STI to its original glory, fixing fuel delivery issues, or ensuring your track build gets the exact fuel flow it needs, this OEM fuel cell is engineered to Subaru’s strict specifications to give you reliability you can count on.
Many enthusiasts underestimate just how critical the fuel cell assembly is to overall performance. Your fuel system is the lifeline of your EJ engine. Every wide-open-throttle pull, every redline shift, and every daily drive depends on steady fuel delivery. An aftermarket or low-quality replacement tank can cause headaches ranging from fuel leaks to inaccurate fuel level readings to poor engine performance.

Factory Fitment – Direct bolt-on replacement, no modifications required.
Superior Durability – Built with OEM-grade materials resistant to rust, corrosion, and impact.
Reliable Fuel Delivery – Maintains consistent fuel pressure for both stock and tuned engines.
Peace of Mind – Tested and validated by Subaru to meet original safety and performance standards.
After all, why gamble with your Subaru’s performance when you can get the exact component it rolled off the factory line with?
The assembly is more than just a shell for storing fuel—it’s an integrated part of your vehicle’s performance system. The OEM assembly is designed to:
Securely house your fuel and minimize evaporation losses.
Work seamlessly with your factory fuel pump, lines, and sensors.
Ensure your sending unit communicates accurately with your fuel gauge.
Provide maximum safety, reducing the risk of leaks or fire in demanding conditions.
Whether you’re replacing a rusted tank, dealing with a failed assembly, or simply upgrading for long-term reliability, this OEM fuel cell gives you everything you need for a hassle-free install.
This OEM assembly is designed specifically for the 2004 Subaru WRX STI, guaranteeing compatibility without the need for custom adjustments. It’s perfect for:
Daily Driving – Keep your STI running smoothly without worrying about hidden leaks or weak welds.
Restorations – Bring your 2004 model back to factory specifications.
Track Builds – Ensure consistent fuel delivery under high G-forces and aggressive driving.
Long-Term Reliability – A one-time investment that protects the heart of your Subaru.
Imagine going into a spirited canyon run or a weekend track event—would you trust your performance to anything less than OEM?
Installation is designed to be straightforward, though some mechanical knowledge is recommended. Here’s a simplified process:
Lift and Secure the Vehicle – Safety first: elevate your WRX STI and ensure proper support.
Drain and Remove Old Tank – Disconnect lines, wiring, and mounting points carefully.
Transfer Fuel Pump & Sending Unit – Move existing components if necessary (or replace if worn).
Install New OEM Assembly – Bolt it into place using the factory mounting points.
Reconnect and Test – Hook up the lines and electrical connections, then test for leaks and gauge accuracy.
If you’re not comfortable handling fuel system components, we recommend professional installation. But for many WRX STI owners, this is a satisfying weekend project.
The aftermarket might tempt you with lower upfront costs, but with fuel systems, shortcuts can be costly. Non-OEM tanks may:
Have poor welds or fitment issues.
Fail prematurely under track stress.
Throw off your fuel level readings.
Compromise safety in the event of an accident.
By choosing the 04 WRX STI GAS TANK FUEL CELL ASSEMBLY OEM, you’re investing in:
Proven Subaru engineering.
Guaranteed fit and function.
Long-term reliability and safety.
Isn’t your Subaru STI worth the best?
Q1: Will the 04 WRX STI GAS TANK FUEL CELL ASSEMBLY OEM fit other WRX or STI models?
This assembly is specifically engineered for the 2004 Subaru WRX STI. While some WRX models share similar layouts, this fuel cell assembly is optimized for the STI chassis and is not guaranteed to fit other years or trims without modification.
Q2: How long will the OEM fuel cell assembly last?
With proper care and maintenance, an OEM fuel cell assembly can last well over a decade. Factors like exposure to road salt, harsh climates, and lack of underbody protection can shorten lifespan, but OEM-grade materials are designed to resist corrosion and wear better than aftermarket alternatives.
Your Subaru is more than a car—it’s a statement of performance, passion, and reliability. Don’t let something as essential as your fuel system be compromised by inferior parts. The 04 WRX STI GAS TANK FUEL CELL ASSEMBLY OEM ensures your Subaru stays true to its heritage: dependable under pressure, precise in engineering, and built to last.
