Early Bronco 23 Gallon Fuel Tank
Long Range Early Bronco Fuel Tanks – High Capacity 66-77 Ford Bronco Upgrades
Early Bronco gas tanks didn’t leave much room for long drives. With just 13 gallons in the rear tank—or 21 gallons total if equipped with dual tanks—range was always limited. That’s fine for cruising around town, but it doesn’t cut it for longer trips or trail runs.
These long range Early Bronco fuel tanks are built to fit 1966-77 Ford Broncos and offer significantly more capacity than the factory setup. These tanks can work as a single high-capacity replacements or they can be paired with a front auxiliary tank for even more range. Upgrade your Bronco to a 23 gallon rear gas tank from WILD HORSES 4x4. Drive farther with fewer fuel stops, and enjoy the journey.
Why the M1A1 23-Gallon Fuel Tank Is the Best Gas Tank for Your Early Bronco
Why the M1A1 23-Gallon Fuel Tank Is the Best Gas Tank for Your Early Bronco
If you own a classic 1966–77 Ford Bronco, you know the factory fuel tank leaves a lot to be desired. With just 13 gallons in the stock main tank, range anxiety is real - especially when you're deep in the backcountry or on a long cruise. Add in the risk of rust, leaks, and old-school design flaws, and you've got a clear reason to upgrade.
Enter the WILD HORSES M1A1 23-Gallon Stainless Steel Fuel Tank for 1966-77 Ford Bronco - a purpose-built, no-compromise upgrade that solves every one of those issues and more. Let’s break down why it’s hands-down the best fuel tank you can bolt into your Early Bronco.
Double the Fuel, Double the Fun
Range matters. Whether you're chasing trail miles or highway lines, the stock tank's 13-gallon capacity just doesn’t cut it anymore. The M1A1 ups that to a full 23 gallons, giving you the kind of range you need for all-day rides, long-distance hauls, or that weekend getaway where gas stations are few and far between.
Bonus: if your Bronco still has the original auxiliary tank, this setup gives you a potential 31 gallons on board. That’s freedom right there.
Built Like a Tank—Because It Is One
This isn’t just a larger fuel tank - it’s a better fuel tank. Crafted from 14-gauge stainless steel and fully TIG-welded, the M1A1 is built to outlast your Bronco’s second and third engines. No rust. No leaks. No waving, warping, or pinholes like you see on some thinner tanks. Just a smooth, clean finish and rock-solid durability.
And if you wheel hard, opt for the skid plate version - a 3/16-inch steel plate wraps the bottom like armor. It’s made to shrug off rocks, roots, and trail hits without compromising ground clearance or departure angle.
EFI-Ready, Trail-Tested
Fuel injection swaps are more common than ever, and the M1A1 is ahead of the curve. The EFI version comes with a high-flow in-tank pump that can support up to 630 horsepower, plus proper supply, return, and vent ports. You won’t need to mess with external pumps or retrofitting EFI later - it’s ready when you are.
Running a carb setup for now? No problem. We’ve got you covered with a carb-specific configuration. Either way, you’re future-proofing your rig.
No Starvation, No Surprises
Inside the tank, you’ll find more smart features - like internal baffling, foam, and a fuel tray around the pickup. These aren’t just fancy add-ons. They keep your pump fed on climbs, off-camber sections, or when the tank's running low. It’s performance you’ll appreciate when you’re miles from pavement.
You also get a modern reed-style sending unit for accurate gauge readings, a side drain plug for easy maintenance, and fittings that make hose routing a breeze.
Install It and Forget It
Don’t worry about cutting, welding, or custom brackets. The M1A1 bolts directly into the factory frame location with included hardware. Got a body lift? It’s adjustable to accommodate up to 3 inches without issue. From filler neck to mounting points, it’s designed to fit right - and stay tight.
And yes, the craftsmanship is dialed. Holes line up. Threads are clean. Everything just works.
Final Thoughts: One Tank to Rule Them All
If you're serious about building a capable, dependable Early Bronco, this is the tank to run. It fixes the range issue. It eliminates corrosion problems. It’s trail-ready, EFI-ready, and install-friendly. And it just looks good under the rig.
We’re not into gimmicks - just solid gear that works. The M1A1 23-Gallon Stainless Steel Fuel Tank is the real deal.
