Fuel System Logic
SYSTEM TYPE
Automatic Siphon Transfer
Non-destructive auxiliary system engineered for all model years of the LC71 (4.0L Gas / 2.8T Diesel). Seamlessly integrates with the 90L OEM primary tank without requiring additional mechanical pumps or complex electrical wiring. Fuel is automatically replenished via the factory venturi system, ensuring fail-safe reliability for remote overland travel.
Gauge Behavior: The factory fuel gauge will remain at the "Full" position while fuel is actively being drawn from the 30L auxiliary tank. Once the auxiliary fuel is fully depleted, the gauge will decline naturally to reflect the 90L primary tank's level. Please note that due to the upgraded combined capacity, the ECU’s Estimated Range (DTE) cannot be calculated with absolute precision and should be utilized as a general reference only.
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.
