Coming Soon! 2000-2006 Toyota Tundra Auxiliary Fuel Tank System 18 Gallon
Description
The Helivue Design 18-Gallon Auxiliary Fuel Tank System is purpose-built for 2000-2006 Toyota Tundra (1st Gen) owners who demand more range without sacrificing ground clearance or factory functionality. Designed, built, and tested 100% in the USA - right out of Colorado - this system is engineered for the daily commuter and the hardcore overlander alike. Constructed from thick 1/8" 5052 aluminum alloy, it delivers superior corrosion resistance and the rugged durability to handle everything from highway miles to high-altitude off-road terrain.
The system integrates seamlessly with your Tundra, tucking neatly above the bumper line so it stays nearly invisible while keeping all factory evap systems intact. It fills through your OEM filler neck, simultaneously topping off both tanks at once - no extra steps, no hassle. With a sloped bottom design that lets you access the residual 2.5 gallons and a side-corner fuel pickup for transferring fuel to others, this is a no-compromises solution for serious off-road and long-distance driving.
Key Features
- 18-Gallon Capacity: Adds a full 18 gallons of auxiliary fuel storage, extending your Tundra's range dramatically for long hauls and remote adventures.
- 1/8" 5052 Aluminum Construction: Thicker-than-standard aluminum with superior corrosion resistance - built to take punishment on and off the road.
- OEM Split Fill Point: Fills through your factory filler neck and simultaneously fills both the auxiliary and factory tanks at once - no separate fill port needed.
- Sloped Bottom Design: Tank bottom is angled to allow use of the residual 2.5 gallons of fuel, so you're never leaving range on the table.
- Side-Corner Fuel Pickup: Dedicated side-corner pickup port makes it easy to transfer fuel to another vehicle when needed.
- Reduced Leak Paths: Simplified design eliminates unnecessary complexity and excess hosing, minimizing potential leak points for long-term reliability.
- High-Clearance, Low-Profile Install: Tucks above the bumper line and stays nearly invisible - no compromise to ground clearance or aesthetics.
- Factory Evap System Preserved: Keeps all OEM evaporative emission systems in place - no cutting corners on compliance or function.
- Programmable Fuel Transfer Switch & Gauge: Includes a quality programmable transfer switch and fuel level gauge so you always know what's in the auxiliary tank.
- Made in Colorado, USA: 100% designed, manufactured, and tested domestically - proven at elevations from 5,000 to 13,000 feet without failure.

Why You'll Love It
Helivue Design built this system because serious Tundra owners deserve an auxiliary fuel solution that doesn't cut corners - and this tank delivers exactly that. It's been beaten, bashed, landed on, and driven hard through Colorado's Rocky Mountains from 5,000 to 13,000 feet of elevation without a single failure, giving you the kind of real-world confidence that lab testing alone can't provide. The all-American manufacturing means every weld, every fitting, and every component is held to a standard that imported alternatives simply can't match. Whether you're a facilities manager running a fleet, a coach hauling equipment across the state, or an overlander pushing deep into the backcountry, this system quietly adds 18 gallons of range without changing the look or function of your truck. Trusted by commuters and off-road enthusiasts who refuse to compromise, the Helivue Design auxiliary tank is the last fuel range upgrade your 1st Gen Tundra will ever need.

FAQ
Will this tank work with my 2000-2006 Toyota Tundra?
Yes - this auxiliary fuel tank system is specifically designed and fitment-tested for the 2000-2006 Toyota Tundra (1st Generation). It is not compatible with other model years or trims outside of this range. If you're unsure about your specific configuration, feel free to email us at service@omahasportsandgames.com before purchasing.
Does this system require any modifications to my factory fuel or evap system?
No - one of the standout features of this system is that it keeps all factory evaporative emission systems in place. It fills through your OEM filler neck and integrates with your existing setup without requiring you to cut, remove, or relocate any factory components.
How does the auxiliary tank fill - do I need a separate filler port?
No separate filler port is needed. The Helivue Design system uses an OEM split fill point, meaning fuel flows through your factory filler neck and simultaneously fills both the factory tank and the auxiliary tank at the same time. It's a seamless, user-friendly experience.
How difficult is the installation, and do I need a professional to install it?
Helivue Design recommends approximately 5 hours for a typical install, and the kit includes all necessary hardware - stainless steel clamps, hardware, bung, fuel pump, transfer switch, and more. A mechanically inclined owner comfortable with fuel system work can complete the install, but if you have any doubts, a professional mechanic or 4x4 shop familiar with fuel systems is always a good choice.
Is this tank safe for high-altitude and off-road use?
Absolutely. This system has been extensively tested in real-world Colorado conditions, driven regularly between 5,000 and 13,000 feet of elevation through demanding terrain. The simplified design reduces leak paths, and the thick 1/8" 5052 aluminum construction is chosen specifically for its toughness and corrosion resistance in harsh environments.
Does the spare tire need to be relocated for installation?
Yes - according to the product specifications, spare tire relocation is required as part of this installation. The kit is designed with this in mind, and the installation process accounts for it within the recommended 5-hour install time.
