SYSTEM TYPE
Direct Replacement (OEM Integrated)
High-capacity primary tank upgrade engineered specifically for the 2010+ FJ Cruiser 4.0L. Designed to replace the restrictive 73L factory tank, integrating seamlessly with Toyota’s OEM fuel delivery and EVAP emissions systems. Retains 100% factory functionality and ensures a codes-free installation for long-distance remote touring.
Gauge Behavior: The factory gauge remains fully functional. Due to the upgraded 113L capacity, the low-fuel warning triggers with a physical reserve of approx. 19L. Your remaining range (DTE) is dynamically calculated by the vehicle's computer based on real-time consumption; this typically translates to a reliable 110km - 130km+ of safety buffer for your journey.
