Built from 1\/8\" 5052 aluminum in Colorado, this tank is lightweight, high-clearance, and designed to tuck above the bumper line so it stays nearly invisible. It installs directly onto existing frame locations with minimal modification, preserving your KDSS, factory air ride, and Class 4 receiver hitch exactly as they came from the factory.\n\u003c\/p\u003e\n\u003cp\u003e\n  Fueling is seamless - the auxiliary tank fills simultaneously with your main tank through the factory filler neck, so there's no extra step at the pump. A programmable fuel transfer switch, quality fuel pump, stainless steel fuel level sender, and all necessary hardware are included so you have everything to complete the install. This system has been tested extensively from 5,000 to 13,000 feet of elevation under real overland conditions, and it shows.\n\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e18-Gallon Capacity:\u003c\/strong\u003e Adds substantial range for long-haul travel, remote off-road trips, or daily commuting in areas with limited fuel access.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1\/8\" 5052 Aluminum Construction:\u003c\/strong\u003e Thicker gauge aluminum with superior corrosion resistance keeps the tank durable and lightweight for years of hard use.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMade in the USA:\u003c\/strong\u003e 100% designed, built, and tested in Colorado - no outsourced manufacturing or compromises on quality control.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSimultaneous Dual-Tank Fill:\u003c\/strong\u003e Fills through the OEM filler neck at the same time as your factory tank - no separate fill point needed.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePreserves Factory Systems:\u003c\/strong\u003e Compatible with KDSS, factory air ride, and Class 4 receiver hitch - nothing gets removed or permanently modified.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh-Clearance, Low-Profile Design:\u003c\/strong\u003e Tucks above the bumper line for an almost invisible installation that doesn't compromise ground clearance.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReduced Leak Paths:\u003c\/strong\u003e Simplified hose routing and fewer connections mean fewer potential failure points in the field.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Corner Fuel Pickup:\u003c\/strong\u003e Allows you to use the auxiliary tank to transfer fuel to another vehicle if needed - a practical feature for remote travel.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt-In Installation:\u003c\/strong\u003e Uses existing frame mounting locations with almost no modification required - recommended install time is approximately 5 hours.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComplete Kit Included:\u003c\/strong\u003e Comes with a programmable fuel transfer switch, fuel level gauge, quality fuel pump, stainless steel fuel level sender, stainless steel clamps, stainless steel hardware, and bung.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eShipping\u003c\/h2\u003e\n\u003cp\u003ePlease email us at service@omahasportsandgames.com for a delivery ETA or to confirm shipping details.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eWhat's Included\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e18-gallon aluminum auxiliary fuel tank\u003c\/li\u003e\n  \u003cli\u003eProgrammable fuel transfer switch \/ fuel level gauge\u003c\/li\u003e\n  \u003cli\u003eQuality fuel pump\u003c\/li\u003e\n  \u003cli\u003eStainless steel fuel level sender\u003c\/li\u003e\n  \u003cli\u003eStainless steel clamps\u003c\/li\u003e\n  \u003cli\u003eStainless steel hardware\u003c\/li\u003e\n  \u003cli\u003eBung\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eWhy You'll Love It\u003c\/h2\u003e\n\u003cp\u003e\n  The Helivue Design GX550 auxiliary fuel system is built for people who push their vehicles hard and rely on them in situations where running out of fuel isn't an option. It's been beaten, bashed, and driven over rough terrain at high elevation without failure - this is a tank that earns its reputation in the real world, not just on a spec sheet. The bolt-in design means you're not cutting corners or voiding factory systems, and the clean above-bumper fitment keeps your rig looking purpose-built rather than cobbled together. Manufactured entirely in the USA, it reflects the kind of craftsmanship that overlanders and off-road enthusiasts have come to trust for demanding builds. Whether you're crossing remote stretches of the American West or simply want the peace of mind that comes with 18 extra gallons on board, this system delivers confidence mile after mile.\n\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eProduct Specifications\u003c\/h2\u003e\n\u003cdiv class=\"custom-product-faq\"\u003e\n\u003cdetails\u003e\n\u003csummary\u003e\u003cstrong\u003eView Product Specs\u003c\/strong\u003e\u003c\/summary\u003e\n\u003ctable border=\"1\"\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eHelivue Design\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eTank Type\u003c\/th\u003e\n\u003ctd\u003eAuxiliary\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eCapacity\u003c\/th\u003e\n\u003ctd\u003e18 Gallons\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e25 Pounds\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003e1\/8\" 5052 Aluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eFill Point\u003c\/th\u003e\n\u003ctd\u003eOEM Split (fills through factory filler neck)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eFuel Type\u003c\/th\u003e\n\u003ctd\u003eGasoline\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eSpare Tire Relocation Required\u003c\/th\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eRecommended Install Time\u003c\/th\u003e\n\u003ctd\u003e5 Hours\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eCompatibility\u003c\/th\u003e\n\u003ctd\u003e2024-Current Lexus GX550\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eCountry of Manufacture\u003c\/th\u003e\n\u003ctd\u003eUSA (Colorado)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003cdiv class=\"custom-product-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eDoes installing this auxiliary tank require cutting or permanently modifying my GX550?\u003c\/summary\u003e\n    \u003cp class=\"faq-content\"\u003eAlmost no modification is required.
