15.5 Gal Fuel Tank Steel 78-86 Jeep CJ

The 15.5 gallon fuel tank steel 78-86 Jeep CJ is a purpose-built replacement fuel cell designed for serious off-road and classic vehicle enthusiasts who demand reliability in remote conditions. Whether you're running a vintage Jeep CJ through backcountry trails or restoring a collector's vehicle to original specifications, this tank delivers the capacity and durability required for extended expeditions away from fuel stops. Built by Holley, a trusted name in fuel system engineering, this steel tank replaces the OEM fuel cell in 1978–1986 Jeep CJ models with proven, dependable performance.

Constructed from heavy-duty steel and finished with a durable silver powder coat, the tank resists corrosion and impact damage inherent to off-road use. The 15.5-gallon capacity provides extended range between refueling, critical for backcountry navigation where gas stations are sparse. Steel construction offers superior puncture resistance compared to plastic alternatives, a significant advantage when navigating rocky terrain, water crossings, or dense brush. The compact footprint—19 × 12 × 28 inches—fits the original CJ mounting points without modification, ensuring straightforward installation and maintaining factory clearance around suspension, frame, and interior components.

This tank is ideal for restorers seeking OEM-style authenticity and off-road adventurers who prioritize fuel range and durability over lighter alternatives. Installation is direct on 1978–1986 Jeep CJ and early Wrangler platforms, requiring no modifications to frame or fuel system plumbing. At 17.63 pounds when empty, it adds minimal weight while maximizing capacity, making it the practical choice for expeditions, trail events, and daily-driver restorations where reliability cannot be compromised. Verify your model year and mounting configuration before purchase to ensure compatibility.
