2010-2022 Toyota 4Runner Auxiliary Fuel Tank System 18 Gallon
Description
The Helivue Design 18 Gallon Auxiliary Fuel Tank System is a precision-engineered, American-made solution for 5th Gen Toyota 4Runner owners who refuse to be limited by range. Built from 1/8" 5052 aluminum and finished in a hammer satin black powder coat, this system is as tough as the terrain it's designed for - tested regularly from 5,000 to 13,000 feet without failure. It mounts invisibly above the bumper line, preserving your factory KDSS, factory air ride, and Class 4 receiver hitch without compromise.
Filling is seamless - just use your factory filler neck and both tanks fill simultaneously. When it's time to transfer fuel, the included programmable transfer switch, fuel pump, and stainless steel fuel level sender make the process clean and simple. Whether you're a daily commuter stretching your range or a hardcore overlander pushing deep into the backcountry, this system is built to go where you go.
Key Features
- 18-Gallon Capacity: Dramatically extends driving range for long hauls, off-grid adventures, and overlanding expeditions.
- 1/8" 5052 Aluminum Construction: Thicker-gauge, corrosion-resistant aluminum delivers serious durability without unnecessary weight.
- Hammer Finish Satin Black Powder Coat: Rugged, attractive finish that holds up against trail abuse and the elements.
- OEM Split Fill Point: Fills through the factory filler neck - both the main and auxiliary tanks fill simultaneously, no extra steps required.
- High-Clearance, Low-Profile Design: Tucks above the bumper line and remains nearly invisible while keeping ground clearance intact.
- KDSS, Air Ride & Hitch Compatible: Specifically designed to retain your factory KDSS system, air ride suspension, and Class 4 receiver hitch.
- Side-Corner Fuel Pickup: Allows you to share fuel with another vehicle ("fill a friend") directly from the auxiliary tank.
- Reduced Leak Paths: Simplified design minimizes hose complexity and leak potential for long-term reliability.
- Programmable Transfer Switch & Fuel Level Gauge: Included high-quality switch lets you manage fuel transfer with precision and monitor levels at a glance.
- 100% Designed & Built in Colorado, USA: Every system is engineered and manufactured in the USA, with all hardware included for a complete install.

FAQ
Will this system work with my factory KDSS or air ride suspension?
Yes - the Helivue Design auxiliary tank is specifically engineered to retain your factory KDSS (Kinetic Dynamic Suspension System), factory air ride, and Class 4 receiver hitch. You won't need to remove or modify any of these systems to install the tank.
How does the tank fill - do I need a separate filler port?
No separate filler port is needed. The system uses an OEM split fill point, meaning you fill through your factory filler neck just like normal. Both your main tank and the auxiliary tank fill simultaneously, so there's no extra step or separate fueling process.
Does installing this tank require relocating the spare tire?
Yes, spare tire relocation is required as part of this installation. This is expected for auxiliary undertray fuel systems on the 4Runner and is factored into the recommended 4-hour install time.
How do I transfer fuel from the auxiliary tank to the main tank?
The kit includes a high-quality programmable fuel transfer switch and fuel level gauge, along with a fuel pump and stainless steel fuel level sender. When you're ready to transfer fuel, simply use the included transfer switch to pump fuel from the auxiliary tank into the main tank. The gauge lets you monitor levels so you always know what you have available.
Is professional installation recommended, or can I do this myself?
The system is designed to be installed by a capable DIYer with basic mechanical skills. Helivue Design estimates a recommended install time of 4 hours, and everything you need is included in the kit - stainless steel clamps, hardware, bung, and all components. If you're not comfortable working with fuel systems, professional installation is always a safe option.
What years and models is this system compatible with?
This specific system is designed for the Toyota 4Runner 5th Generation, covering model years 2010 through 2024. Helivue Design also offers separate auxiliary tank systems for 2003-2009 4Runners, 2023-2024 4Runners, and other Toyota models including the Tacoma.
