2023-2024 Toyota 4Runner Auxiliary Fuel Tank System 18 Gallon

Description

The Helivue Design 18 Gallon Auxiliary Fuel Tank System is a no-compromises solution for 2023-2024 Toyota 4Runner owners who demand serious range without sacrificing factory functionality. Designed, built, and tested 100% in the USA - right out of Colorado - this lightweight aluminum tank tucks neatly above the bumper line, keeping your KDSS, factory air ride, and Class 4 receiver hitch fully intact. The system fills through your factory filler neck, simultaneously topping off both tanks at once, so fueling up is as seamless as it gets.

Built from 1/8" 5052 aluminum with a hammer finish satin black powder coat, this tank is engineered to handle the punishment of serious overlanding - tested regularly from 5,000 to 13,000 feet of elevation without failure. Whether you're a daily commuter looking to stretch fuel stops or a hardcore overlander pushing deep into the backcountry, this system delivers the extended range and reliability you need.

Key Features

• 18-Gallon Capacity: Adds a full 18 gallons of auxiliary fuel range, dramatically extending time between fill-ups on long hauls or remote trails.

Why You'll Love It

Helivue Design built this system for people who take their 4Runner seriously - whether that means a 500-mile daily commute week or a week-long overland expedition far from the nearest gas station. This isn't a bolt-on compromise; it's a purpose-engineered system that keeps every factory feature intact while adding a full 18 gallons of range. Made in the USA from premium 5052 aluminum and proven at high altitude under punishing real-world conditions, this tank is the kind of gear you install once and trust for years. The clean, above-bumper-line fitment means no one will even know it's there - until you pull up to the pump half as often as everyone else. For overlanders, off-roaders, and long-distance commuters who refuse to sacrifice capability for convenience, the Helivue Design auxiliary fuel system is the definitive upgrade for your 5th Gen 4Runner.
