The LongRanger TR88L 143-litre replacement diesel fuel tank is engineered specifically for Isuzu D-Max 4x4 models from 2020 onwards. Designed to directly replace the factory tank, this upgrade dramatically increases your vehicle’s fuel capacity, making it ideal for drivers who demand greater range for touring, overlanding, or remote work. LongRanger’s reputation for robust, fit-for-purpose fuel solutions ensures that this tank integrates seamlessly with your D-Max’s existing fuel system.
This replacement tank is not an auxiliary add-on but a full replacement for the original underbody fuel tank. By occupying the same mounting location, it preserves the factory fuel system configuration and eliminates the need for external jerry cans or additional tanks. The TR88L increases the D-Max’s diesel capacity to 143 litres, representing an approximate 89% boost over the standard tank. This substantial increase allows for significantly longer distances between refuelling stops, which is crucial for remote expeditions and extended journeys.
The TR88L is purpose-built for Isuzu D-Max owners who regularly travel long distances, venture off-road, or operate in regions where fuel stations are scarce. It is especially valuable for:
By retaining the original tank location and factory-style plumbing, the TR88L maintains the integrity of the D-Max’s fuel delivery system while delivering the longest possible range for this platform.
The LongRanger TR88L is designed for direct replacement, using the original mounting points and fuel system connections. Due to the increased volume, the tank sits approximately 45 mm lower than the factory bash plate on 4WD models—a common trade-off for maximum capacity. Professional installation is recommended to ensure correct fitment and integration with the vehicle’s fuel system. No modifications to the fuel system layout are required, and the tank is engineered to work with the D-Max’s diesel platform from 2020 onwards.
For D-Max owners tackling remote routes or extended journeys, limited fuel range can restrict travel plans and add risk. The TR88L addresses this by nearly doubling the available fuel capacity, reducing the need for frequent stops and providing peace of mind when travelling far from refuelling points. This is especially important for overlanders, remote workers, and anyone who values self-reliance in challenging environments.

The tank sits approximately 45 mm lower than the factory bash plate on 4WD models. This is typical for high-capacity tanks and should be considered if maximum clearance is a priority.
No, the TR88L is engineered specifically for diesel-powered Isuzu D-Max models from 2020 onwards. It is not compatible with earlier models or petrol engines.
While the tank is a direct replacement, professional installation is recommended to ensure proper integration with the factory fuel system and to maintain safety standards.
The TR88L is designed to retain the factory fuel system layout, but recalibration of the fuel gauge may be necessary to accurately reflect the increased capacity. Consult your installer for details.
The TR88L offers a fully integrated solution, eliminating the need for external containers, reducing spillage risk, and keeping all fuel securely mounted under the vehicle.
The TR88L is designed as a direct replacement, but always confirm included hardware with your supplier or installer before purchase.
