LongRanger TR88L 143L Replacement Diesel Fuel Tank – Isuzu D-Max 2020+ Long Range Upgrade

Extended Range Solution for Isuzu D-Max 2020+ Diesel Models

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.

How the TR88L Replacement Fuel Tank Works

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.

Where the LongRanger TR88L Tank Excels

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:

• Overlanders and expedition travellers seeking maximum self-sufficiency
• Touring enthusiasts covering extended routes without frequent stops
• Work vehicles operating in remote or rural areas
• Drivers wanting to reduce reliance on portable fuel containers

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.

Technical Specifications

Installation and Practical Considerations

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.

Real-World Problem Solved

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.
