Under-Chassis Auxiliary 35L Fuel Tank – Suits INEOS Grenadier (Diesel) | Aftermarket
Overview Cruising the remote outback demands heavy-duty fuel security. While the INEOS Grenadier is built for brutal terrain, its factory 90L capacity quickly falls short when tracks turn punishing and remote fuel stops are up to 400 km apart. This under-chassis auxiliary fuel tank is the ultimate fix. Adding an extra 35L of diesel capacity to your setup, it mounts securely in the middle of your vehicle’s undercarriage without encroaching on your interior space or roof load limits. Engineered to handle corrugated roads, steep washouts, and unforgiving obstacles, it gives you the absolute confidence to push further into the deep country. Features Premium stainless steel tank construction built for punishing environments Expands fuel reserves by 35L to eliminate range anxiety between remote outback supply lines Under-chassis center-mount design keeps the vehicle’s center of gravity low.
