Technical Specifications

Installation and Practical Considerations

The TR74L is designed for straightforward installation in place of the factory tank, using original mounting points and fuel system connections. Note that on 4WD models, the tank sits around 45 mm lower than the standard bash plate—a typical characteristic of high-capacity replacement tanks. This should be considered if your build prioritises maximum ground clearance for technical off-road use.

No additional fuel pumps or complex wiring are required; the system is fully compatible with the D-Max’s existing fuel sender and lines. Professional installation is recommended for best results and safety compliance.

Why Choose the LongRanger TR74L for Your Isuzu D-Max?

For owners planning extended journeys, remote expeditions, or simply seeking fewer fuel stops, the LongRanger TR74L offers a proven solution. Its direct replacement design means no compromise on reliability or integration, and it removes the inconvenience and safety risks of carrying loose fuel containers. Widely trusted in off-road and touring builds, LongRanger tanks are engineered for demanding environments where range and dependability are critical.
