Fuel System Logic
SYSTEM TYPE
Direct Replacement (OEM Sub-Tank Integrated)
Premium high-capacity auxiliary (sub) tank precision-engineered for the 2022+ Toyota Land Cruiser 300 3.3T Diesel with factory dual fuel tanks. Designed to directly replace the 30L factory sub-tank with an upgraded 52L capacity, expanding total onboard diesel volume from 110L to 132L. It integrates seamlessly with Toyota’s OEM dual-tank fuel management, pump transfer, and emission control systems, retaining 100% factory switch logic with zero diagnostic codes.
Gauge Behavior: The factory dual-tank display and automatic transfer system remain 100% functional. The upgraded 52L sub-tank causes the auxiliary fuel gauge section to decline more gradually than the OEM setup. When the main fuel warning triggers, a physical reserve of approx. 17L remains. Distance to Empty (DTE) is dynamically calculated by Toyota’s ECU based on real-time diesel consumption across both tanks, providing an exceptional 140km - 170km+ safety buffer once the warning activates.
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
Strap Shield Protection System
Recessed mounting pockets allow the tank straps to sit flush within protected zones, reducing the risk of strap damage or snagging when sliding over obstacles off-road.
05
Quick-Connect Fuel Line Fittings
Equipped with OEM-style quick-connect fittings for secure sealing, simplified installation, and reliable fuel line connections.
06
Integrated Drain Port
An integrated drain port allows fuel to be safely drained for maintenance, repairs, or long-term storage without removing the tank.
07
Direct Bolt-On Installation
Designed to mount to factory locations using original mounting points. No chassis cutting, drilling, or permanent modifications required.
08
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.
