Designed for serious overlanders and expedition drivers, this auxiliary tank system increases total fuel capacity without removing the factory tank, supporting extended journeys where fuel stops are scarce.\u003c\/p\u003e\n\n\u003ch2\u003eHow the TA62A Auxiliary Tank Works\u003c\/h2\u003e\n\u003cp\u003eThis LongRanger auxiliary tank is installed in the spare wheel location behind the rear differential, working in tandem with the original 82L factory tank. The system uses an electric transfer pump to move fuel from the auxiliary tank to the main tank as needed, all managed via an automatic cut-off and in-cabin LED gauge for safe, controlled transfer.\u003c\/p\u003e\n\n\u003ch2\u003eWhere This Upgrade Is Useful\u003c\/h2\u003e\n\u003cp\u003eThe TA62A is ideal for Discovery owners planning remote outback travel, long-distance touring, or expeditions where access to diesel is limited. It is especially valuable for vehicles carrying heavy loads, towing, or operating in regions with infrequent fuel stations. By increasing total capacity to approximately 186 litres, drivers can confidently tackle longer routes and remote tracks, reducing the risk of running low on fuel far from help.\u003c\/p\u003e\n\n\u003ch2\u003eKey Benefits of the LongRanger TA62A Auxiliary Tank\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e104 litres of additional diesel storage for extended range\u003c\/li\u003e\n  \u003cli\u003eMaintains factory tank and original filler location with dual filler neck\u003c\/li\u003e\n  \u003cli\u003eElectric transfer pump with automatic shut-off and LED gauge\u003c\/li\u003e\n  \u003cli\u003eNo exhaust modifications required\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty 2 mm aluminised steel construction for off-road durability\u003c\/li\u003e\n  \u003cli\u003eRetains standard departure angle and is compatible with factory tow bars and Kaymar rear bars\u003c\/li\u003e\n  \u003cli\u003eEngineered specifically for Discovery 3 \u0026amp; 4 diesel models (2005–2016), excluding AdBlue-equipped vehicles\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eConstruction and Engineering Details\u003c\/h2\u003e\n\u003cp\u003eLongRanger tanks are manufactured using CAD\/CAM processes and constructed from 2 mm (14-gauge) aluminised steel, providing strength and corrosion resistance for demanding off-road use.
