2025-Current Toyota 4Runner Auxiliary Fuel Tank System 18 Gallon

Description

The Helivue Design 18 Gallon Auxiliary Fuel Tank System is a purpose-built range extender engineered specifically for the 2025 and newer Toyota 4Runner. 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.

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.

Why You'll Love It

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.
