Designed and manufactured 100% in Colorado, this system adds 18 gallons of fuel capacity using a lightweight, high-clearance aluminum tank that tucks neatly above the bumper line - staying virtually invisible while preserving every key factory feature. Unlike bulky aftermarket alternatives, this system is fully compatible with KDSS, Factory Air Ride, and your Class 4 receiver hitch, making it the go-to choice for overlanders and daily drivers who refuse to compromise.\n\u003c\/p\u003e\n\u003cp\u003e\n  The tank fills simultaneously with your main tank through the factory filler neck, so there's no guesswork or extra steps at the pump. Built from thicker 1\/8\" 5052 aluminum with superior corrosion resistance, this system has been tested and beaten across Colorado's Front Range from 5,000 to 13,000 feet of elevation without failure. Whether you're chasing remote trailheads or grinding through long highway commutes, this fuel system gives you the confidence to go further.\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 a full 18 gallons of auxiliary fuel - dramatically extending your 4Runner's range for overlanding, remote travel, or long commutes.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1\/8\" 5052 Aluminum Construction:\u003c\/strong\u003e Thicker aluminum alloy provides superior corrosion resistance and durability over standard tank materials.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOEM Split Fill Point:\u003c\/strong\u003e Fills simultaneously through your factory filler neck alongside the main tank - no separate filling process required.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePreserves KDSS, Factory Air Ride, and Class 4 Hitch:\u003c\/strong\u003e Designed so you keep every key factory system intact - no sacrifices to install this tank.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh-Clearance, Low-Profile Design:\u003c\/strong\u003e Tucks above the bumper line and remains nearly invisible, preserving approach and departure angles.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimal Modification Required:\u003c\/strong\u003e Bolts directly into existing frame locations with almost no drilling or custom fabrication needed.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Corner Fuel Pickup:\u003c\/strong\u003e Built-in side pickup allows you to transfer fuel to another vehicle when needed - great for trail groups and remote expeditions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReduced Leak Paths:\u003c\/strong\u003e Simplified design eliminates unnecessary complexity and extra hosing to minimize potential failure points.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProgrammable Fuel Transfer System Included:\u003c\/strong\u003e Kit comes with a programmable fuel transfer switch, fuel level gauge, quality fuel pump, and stainless steel fuel level sender.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e100% USA Designed, Built, and Tested:\u003c\/strong\u003e Engineered and manufactured in Colorado, and proven on real terrain from 5,000 to 13,000 feet elevation.\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 5052 aluminum auxiliary fuel tank\u003c\/li\u003e\n  \u003cli\u003eProgrammable fuel transfer switch with 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  Helivue Design built this system for people who actually use their 4Runner - the overlanders pushing deep into the backcountry and the commuters logging serious highway miles far from the nearest fuel station. This isn't a compromise-filled bolt-on; it's a precision-engineered solution that respects your 4Runner's factory engineering while meaningfully extending what it can do. The fact that it keeps KDSS, factory air suspension, and your receiver hitch fully functional speaks to how thoughtfully it was designed. Proven at altitude across Colorado's most demanding terrain, this tank isn't just tough on paper - it's been validated in the real world. With everything needed for installation included in the kit and a recommended install time of just 5 hours, you'll be on the road with extended range faster than you'd expect. If you're serious about your 4Runner's capability, this is the fuel system it deserves.\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\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 (simultaneous fill 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\u003eToyota 4Runner 2025 - Current\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eManufactured In\u003c\/th\u003e\n\u003ctd\u003eColorado, USA\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\u003eWill this tank work with my 4Runner's KDSS or factory air ride suspension?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eYes - the Helivue Design auxiliary tank is specifically engineered to maintain full compatibility with KDSS (Kinetic Dynamic Suspension System), factory air ride, and your Class 4 receiver hitch.
