Fuel System Logic
SYSTEM TYPE
Direct Replacement (OEM Integrated)
Premium high-capacity replacement tank engineered specifically for the LC71 2.8T Diesel. Precision-designed to replace the 90L factory unit, expanding total onboard fuel to 139L. It integrates seamlessly with Toyota’s OEM fuel delivery and ventilation systems, retaining 100% factory functionality and reliability for extended overland expeditions.
Gauge Behavior: The factory gauge remains fully functional. Due to the expanded 139L capacity, the low-fuel warning triggers with a physical reserve of approx. 22L. Your remaining range (DTE) is dynamically calculated by the vehicle's computer based on real-time diesel consumption; this typically translates to a generous 180km - 220km+ of safety buffer depending on your driving conditions.
Structure & Protection Design
01
02
Internal Baffle System
Internal baffles help control fuel movement inside the tank, improving vehicle stability and fuel pickup reliability on uneven terrain.
03
Heat Shield Protection
Integrated heat shielding reduces exhaust heat exposure and helps protect fuel system components from excessive temperature.
04
Quick-Connect Fuel Line Fittings
Equipped with OEM-style quick-connect fittings for secure sealing, simplified installation, and reliable fuel line connections.
05
Integrated Drain Port
An integrated drain port allows fuel to be safely drained for maintenance, repairs, or long-term storage without removing the tank.
06
Direct Bolt-On Installation
Designed to mount to factory locations using original mounting points. No chassis cutting, drilling, or permanent modifications required.
07
Individual Serial Identification
Each tank is marked with a unique serial number for product identification, quality tracking, and authenticity verification.
Weight & Material Engineering
Designed to reduce weight without compromising strength, ideal for long-range and overland use.
