Why the 2011-2014 WRX STI Fuel Cell Gas Tank Assembly Matters

Your STI’s performance depends on a clean and reliable fuel system. Even the most powerful EJ engine can’t deliver if it doesn’t have a steady, uncontaminated supply of fuel. The 2011-2014 WRX STI FUEL CELL GAS TANK ASSEMBLY ensures that:

• Fuel Flow is Consistent – Maintains the pressure your high-performance turbocharged engine demands.

• OEM Reliability – Genuine Subaru engineering guarantees a direct fit with zero modifications.

• Safety First – Prevents leaks and hazards that could put you and your vehicle at risk.

• Longevity – Built to withstand daily driving and performance demands without premature wear.

Unlike aftermarket alternatives, OEM Subaru assemblies are tested under the same conditions as your vehicle was when it left the factory. That means peace of mind every time you start your car.

What Comes with the 2011-2014 WRX STI Fuel Cell Gas Tank Assembly

This isn’t just a bare tank—it’s a full fuel cell gas tank assembly designed for complete integration with your 2011, 2012, 2013, or 2014 WRX STI. The assembly may include:

• Fuel tank shell engineered to factory spec.

• Mounting points for OEM straps and hardware.

• Compatibility with factory fuel pump and sending unit.

• Precise fitment with stock fuel lines and EVAP system.

That means no cutting, bending, or retrofitting—just seamless installation for OEM performance.

Where This Fuel Cell Gas Tank Assembly Makes the Difference

So, when do you really need the 2011-2014 WRX STI FUEL CELL GAS TANK ASSEMBLY?

• Restoration Projects: Bringing an older STI back to showroom condition means starting with core components like the fuel system.

• Accident Repairs: If your STI has suffered underbody damage, the tank may be compromised, and replacement is a must.

• Rust & Corrosion Issues: Many Subarus live in harsh climates where road salt and moisture can eat away at fuel tanks.

• Performance Builds: For tuners pushing high horsepower, a clean and properly functioning tank ensures reliability.

A compromised fuel cell doesn’t just affect performance—it can end your build before it begins.

How to Install the 2011-2014 WRX STI Fuel Cell Gas Tank Assembly

Replacing a fuel cell gas tank isn’t as simple as swapping wheels, but Subaru engineered the process to be as straightforward as possible.

Step 1: Preparation
Safely lift and support the car. Relieve fuel system pressure and disconnect the battery.

Step 2: Remove Old Tank
Unbolt straps, disconnect filler neck, EVAP lines, and fuel lines, then carefully lower the old tank.

Step 3: Transfer Components
Move over your existing fuel pump, level sending unit, and any necessary sensors.

Step 4: Install the New Tank
Lift the 2011-2014 WRX STI FUEL CELL GAS TANK ASSEMBLY into place, reconnect all lines, and secure straps.

Step 5: Final Checks
Reconnect the battery, prime the fuel system, and check for leaks.

Pro tip: Many Subaru enthusiasts tackle this job in their garage, but professional installation is recommended if you don’t have a lift or fuel system experience.
