Fuel System Logic
SYSTEM TYPE
Integrated Primary Upgrade with Auto-Siphon Sub-Tank
Ultimate high-capacity dual-tank system precision-engineered for the 2022+ INEOS Grenadier (3.0L Turbo I6 Gas B58 / Diesel B57). Features an upgraded 120L replacement primary tank paired with a 45L side-mounted auxiliary tank, boosting total fuel volume from 90L to 165L without sacrificing underbody ground clearance. The auxiliary tank transfers fuel automatically to the expanded primary tank via the OEM venturi system—requiring zero secondary pumps or manual switches for a 100% codes-free overland upgrade.
Gauge Behavior: The factory fuel gauge will remain sustained at the "Full" position for an extended period as fuel automatically transfers from the 45L auxiliary tank. Once depleted, the gauge smoothly registers the upgraded 120L primary tank, declining much more gradually than stock. When the low-fuel warning triggers, a physical reserve of approx. 18L remains in the main tank. Distance to Empty (DTE) is dynamically calculated by the computer and serves as a general reference.
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.
