    Compare Selected

    From WWII-era Willys to modern Wrangler builds, Jeeps demand fuel systems as legendary as the rigs themselves. Our Jeep and Willys gas tank selection serves builders, restorers, and off-road enthusiasts who refuse to compromise. Whether you're restoring an original CJ, upgrading a TJ for desert trails, or protecting a JK's underside with a skid-mounted tank, we have the right solution for your build.

    We carry standard replacement tanks for key Jeep model years as well as high-capacity and skid-plate integrated designs for off-road applications. Materials include durable polyethylene and corrosion-resistant coated steel, engineered to handle the abuse of rock crawling, water crossings, and high-flex terrain. Our tanks are matched to specific model years and configurations to ensure correct fit without modification.

    Find the right gas tank for your Jeep or Willys using the year and model selector above.

    Frequently Asked Questions

    What are the benefits of upgrading to a high-capacity Jeep Wrangler replacement fuel tank?

    Upgrading to a high-capacity tank like the Transfer Flow 29 Gallon system for the Jeep JK significantly extends your driving range for overlanding and remote trail riding. These heavy-duty tanks replace the smaller factory unit, allowing you to bypass frequent fuel stops while maintaining ground clearance and structural integrity.

    Will an aftermarket gas tank fit my vintage Jeep CJ7 or Willys MB?

    Yes, manufacturers like Rugged Ridge and Omix-ADA produce specialized 15 and 20-gallon replacement tanks designed specifically for vintage Jeep CJ5, CJ7, and Willys models. These tanks are engineered to match OEM mounting points while offering modern materials that resist rust and corrosion better than original steel units.

    Which Jeep fuel tanks are best for extreme rock crawling and off-roading?

    For technical terrain, the GenRight Rock Crawler series is the industry standard because these tanks feature a high-clearance design that allows for larger rear axles and improved departure angles. These heavy-duty aluminum tanks often come with integrated steel skid plates to protect the fuel system from boulders and trail obstacles.

    Do I need a separate skid plate for my Jeep TJ or JK replacement tank?

    While some tanks like the GenRight and Brown Dog systems include integrated armor, others may require an external skid plate for maximum protection. Always verify if the replacement tank is compatible with your existing factory skid plate or if a specialized heavy-duty version is required to clear the larger dimensions of an extended-range tank.

    How do I choose the right fuel tank size for my Jeep build?

    Selecting the right tank size depends on your wheelbase and suspension modifications, as larger 30-plus gallon options may require specific exhaust or axle configurations. Before purchasing, verify your Jeep model code—such as YJ, TJ, or JK—and check if the tank is designed for fuel-injected engines or carbureted vintage systems to ensure pump compatibility.
