Engineered and manufactured in Australia by Brown Davis — the country's most trusted name in long range fuel solutions since 1978 — this poly tank offers a significant weight saving over its steel equivalent while still delivering a substantial increase in fuel range.\u003c\/p\u003e\n\u003cp\u003eReplacing the factory 76 litre tank with the ISD20R1P brings your total capacity to \u003cstrong\u003e130 litres\u003c\/strong\u003e — a 71% increase — without requiring any vehicle modifications. The tank retains the standard filler point and is designed to reuse the vehicle's original fuel pump sender assembly, keeping the installation clean and straightforward.\u003c\/p\u003e\n\u003cp\u003eFor fleet managers, tradies, and drivers who primarily travel on sealed or semi-sealed roads, the poly tank is an excellent choice. Its lighter weight reduces the overall load on the vehicle compared to a steel equivalent, making it particularly well suited to payload-sensitive applications. Available at \u003cstrong\u003eBrixton 4x4\u003c\/strong\u003e, the ISD20R1P is backed by Brown Davis' 3-year manufacturer's warranty and comes complete with all parts and hardware required for installation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFits: Isuzu D-MAX (2020–Present) — All 4WD Models | Single Cab, Space Cab, Crew Cab | SX, LS-M, LS-U, X-TERRAIN | 3L Engine\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eStep-by-step DIY installation instructions with photographs and diagrams are included with every tank.\u003c\/em\u003e\u003c\/p\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: flex-start; margin-top: 20px;\"\u003e\n\u003cdiv style=\"flex: 1 1 50%; min-width: 300px; padding: 30px 50px 30px 0;\"\u003e\n\u003ch2\u003eWhy Choose the Brown Davis Poly Long Range Fuel Tank?\u003c\/h2\u003e\n\u003cp\u003eBrown Davis manufactures both steel and poly long range fuel tanks, giving customers the right option for their specific use case. The poly tank is the ideal choice for drivers who spend the majority of their time on sealed or well-maintained roads and for whom weight savings are a priority. On average, poly long range tanks are \u003cstrong\u003e10–15 kg lighter\u003c\/strong\u003e than their steel equivalents — a meaningful saving for payload-sensitive vehicles and fleet applications.\u003c\/p\u003e\n\u003cp\u003eFor drivers regularly tackling serious off-road terrain, rock crawling, or remote outback tracks, the steel ISD20R1 may be a more suitable option.
