2022-Current Toyota Tundra Auxiliary Fuel Tank System 18 Gallon


Description

The Helivue Design 18 Gallon Auxiliary Fuel Tank System is a premium, no-compromises range extension solution built specifically for the 2022-and-newer Toyota Tundra. Designed and manufactured 100% in Colorado, this lightweight aluminum tank is engineered for both the daily commuter who wants the freedom of extended range and the hardcore overlander pushing deep into the backcountry. Constructed from thicker 3mm 5052 aluminum with a Hammer Finish powder-coat, this system is built to withstand the harshest conditions - it has been thoroughly beat, bashed, and driven at elevations from 5,000 to 13,000 feet without failure.

One of the most thoughtfully integrated auxiliary fuel systems on the market, this tank preserves your Tundra's KDSS, Factory Air Ride, and Class 4 receiver hitch - no sacrifices required. It tucks above the bumper line for a virtually invisible, high-clearance profile and keeps all factory evap systems in place. Fueling is seamless: fill through your factory filler neck and both tanks fill simultaneously, so you never have to think about switching between them.


Key Features

  • 18-Gallon Capacity: Adds significant range to your Tundra without the bulk of a bed-mounted solution.
  • 3mm 5052 Aluminum Construction: Thicker-than-standard aluminum chosen for superior corrosion resistance and off-road durability.
  • Hammer Finish Powder-Coating: A tough, attractive finish that resists chips, scratches, and the elements.
  • OEM Split Fill Point: Fills through your factory filler neck - both tanks fill simultaneously, requiring zero extra steps at the pump.
  • Preserves KDSS, Air Ride & Class 4 Hitch: Designed specifically so you keep every major factory system intact - no compromises.
  • High-Clearance, Invisible Profile: Tucks above the bumper line for a clean look and maintained ground clearance, critical for overlanding.
  • Bolt-In Installation: Mounts to existing frame locations - almost no modification required. Recommended install time is 5 hours.
  • Programmable Fuel Transfer Switch & Gauge: Includes a high-quality programmable fuel transfer switch with integrated fuel level gauge for easy fuel management.
  • Complete Hardware Kit Included: Stainless steel clamps, stainless steel hardware, bung, quality fuel pump, and stainless steel fuel level sender all included.
  • Made in the USA: 100% designed, built, and tested in Colorado - field-tested at elevation across demanding terrain.

FAQ

Will this auxiliary tank work with my Tundra's KDSS, Factory Air Ride, or receiver hitch?

Yes - this system is specifically designed to preserve all three. You will not need to remove or modify your KDSS system, factory air ride suspension, or Class 4 receiver hitch. This is one of the key engineering priorities of the Helivue Design system.

Does the spare tire need to be relocated?

Yes, spare tire relocation is required with this installation. This is noted in the product specifications. Plan for a spare tire relocation solution as part of your installation process.

Do I need to modify my exhaust system?

Yes, one modification is required - you will need to remove the rearmost tail pipe. This can be done by replacing it with an aftermarket turndown pipe (SXTH Element makes a compatible one) or by cutting the factory rearmost tail pipe down. Other than this, the system bolts into existing frame locations with almost no other modifications needed.

How does the fueling process work? Do I have to fill two separate tanks?

No - fueling is completely seamless. The auxiliary tank fills through your factory filler neck and both tanks fill simultaneously. There is no separate filler point or manual switching required at the pump.

How long does installation take, and can I do it myself?

The recommended install time is approximately 5 hours. The tank bolts into existing frame locations with almost no modification required, and the kit includes all necessary hardware - stainless steel clamps, hardware, bung, fuel pump, and fuel level sender. A mechanically experienced DIYer can handle this installation, though professional installation is always an option for those who prefer it.
