2023 Lexus GX460 Auxiliary Fuel Tank System 18 Gallon

Description

The Helivue Design 2023 Lexus GX460 Auxiliary Fuel Tank System adds 18 gallons of fuel capacity to your GX460 without sacrificing any of the factory equipment you rely on. Designed and manufactured in Colorado, this system is built for commuters and hardcore overlanders alike - tested at altitudes from 5,000 to 13,000 feet under real-world punishment without failure. Constructed from thick 1/8" 5052 aluminum with a hammer finish satin black powder coat, it delivers serious corrosion resistance and rugged durability in a lightweight package.

The system tucks above the bumper line, making it nearly invisible while preserving your KDSS, factory air ride, and Class 4 receiver hitch. It fills through your factory filler neck and simultaneously tops off both tanks at once - no extra steps needed. When you need to transfer fuel on the trail, the included programmable transfer switch, fuel pump, and stainless steel fuel level sender make the process simple and reliable.

Key Features

• 18-Gallon Capacity: Adds a full 18 gallons of usable fuel range - ideal for remote overland routes and long-haul commutes alike.
• 1/8" 5052 Aluminum Construction: Thicker aluminum alloy chosen for superior corrosion resistance and long-term durability in harsh conditions.
• Hammer Finish Satin Black Powder Coat: Aggressive, durable finish that resists chips and corrosion while blending with factory undercarriage aesthetics.
• OEM Split Fill Point: Fills through your factory filler neck - both tanks fill simultaneously with no extra effort or secondary fill point.
• High Clearance, Above-Bumper-Line Profile: Tucks neatly above the bumper line for a stealthy, low-profile install that protects the tank on the trail.
• Preserves KDSS, Factory Air Ride & Class 4 Hitch: No compromises - your factory systems and receiver hitch remain fully intact and functional.
• Corner Fuel Pickup ("Fill a Friend"): Side-corner fuel pickup allows you to gravity-feed or pump fuel to another vehicle when needed.
• Reduced Leak Paths: Simplified design eliminates unnecessary hosing and fittings to minimize potential leak points.
• Programmable Fuel Transfer Switch & Gauge: Included high-quality transfer switch with integrated fuel level gauge gives you full control over fuel management.
• 100% Designed, Built & Tested in the USA: Engineered and manufactured in Colorado - every unit is tested before it ships.

Why You'll Love It

Helivue Design built this system for people who push their GX460 to the limit - whether that means remote overland expeditions across Colorado's backcountry or long daily commutes far from the nearest gas station. Every component is sourced and assembled in the USA, and the tank itself has been driven hard over thousands of miles and extreme elevation changes without a single failure. The no-compromise design philosophy means you don't have to give anything up - your factory KDSS suspension, air ride, and receiver hitch all stay exactly where they belong.

Installation is straightforward with everything included in the kit, and the recommended 4-hour install time means you're back on the road or trail the same day. The nearly invisible profile above the bumper line keeps your GX looking factory-clean while secretly doubling your range. For overlanders, remote workers, and adventurers who can't afford to run dry, this is the auxiliary fuel system built to match the demands of real-world use.
