Add the fuel-side hardware needed for ethanol-content monitoring
COBB 324260 routes fuel through an ethanol-content sensor on supported 2011-2014 WRX applications. The application-specific lines use quick-connect ends, while the bracket locates the sensor near the fuse box for integration with the compatible NexGen system.
Key Features
- 324260 exact sensor-to-fuel-rail line kit for the GR WRX
- Ethanol-content sensor with application-specific mounting bracket
- Two fuel lines with quick-connect ends
- Designed for the compatible COBB NexGen Flex Fuel system
- Manufacturer installation procedure covers fuel-pressure relief, battery removal, line routing, and leak checks
- Vehicle-specific fuel-system component; not a universal hose kit

FAQ
What is the 324260?It is the ethanol-content sensor, bracket, and two fuel-line portion of the compatible NexGen Flex Fuel system for the supported WRX.
Does this kit fit the WRX STI?No. COBB's exact installation data identifies the 2011-2014 Subaru WRX, not the WRX STI.
How many fuel lines are included?Two application-specific fuel lines are included with the ethanol-content sensor and bracket.
Is the NexGen module included?No. The module, harness, and related electronics are separate components of the complete system.
Is a fuel-pressure sensor included?No. A separate compatible fuel-pressure sensor kit is required when the selected system configuration calls for it.
Is calibration required?Yes. Use only a current calibration approved for the exact vehicle, fuel system, electronics, and installed hardware.
Should the fuel system be leak-tested?Yes. COBB directs the installer to prime the system without starting the engine, inspect every connection, and correct any leak before reassembly.
Is professional installation recommended?Yes. The procedure involves depressurizing and opening the fuel system, electrical connections, component routing, and a final leak test.
Installation Instructions
- Confirm the package identifies 324260, then inspect the sensor, bracket, and both fuel lines before opening the vehicle fuel system.
- Work on a fully cooled vehicle in a ventilated area without ignition sources and follow the factory method to relieve fuel pressure.
- Disconnect the negative and positive battery terminals, remove the battery, and remove the intake components required for access.
- Disconnect the original fuel feed line at the firewall and engine using the quick-release fittings.
- Mount the ethanol-content sensor near the fuse box and connect the shorter and longer lines in the COBB-specified orientation.
- Route every fuel line and electrical lead away from abrasion, heat, battery pressure, sharp edges, and moving components.
- Reconnect the battery, prime the fuel system without starting the engine, and inspect every connection repeatedly for leaks.
- Reassemble only after the system is leak-free, then load the correct calibration and verify normal operation before road or full-load use.
