Titan Fuel Tanks is once again revolutionizing the industry with the release of the new Gen 7 XXL Replacement Fuel Tanks. Our tanks are the most advanced and capable XXL fuel tanks ever produced. Constructed from our renowned High-Density Cross-Linked Polyethylene (XLHDPE), they offer unmatched durability and a lifetime warranty, surpassing any other fuel tank on the market.
The Gen 7 tanks boast three innovative new features to maximize versatility:
A fast fill vent kit for hassle free fueling at high-flow truck stop pumps, a universal pickup tube compatible with high-pressure fuel systems, and a transfer pump kit, allowing you to conveniently fuel other vehicles directly from your XXL replacement tank. These kits are optional and sold separately. They can be found at the bottom of this page.
The Titan 50 Gallon Extra Capacity Mid-Ship Replacement Fuel Tank, designed specifically for 2025 Ram 2500 and 3500 pickups with Mega Cabs, Short Beds, and Cummins engines. With this innovative upgrade, you're not just investing in a larger fuel tank - you're investing in unparalleled freedom and convenience on the road.
The tank comes complete with a black-coated, galvanized steel mounting strap and front support system. Plus, with its exclusive low fuel trap design all 50 gallons are usable capacity. We could advertise a larger capacity, but we chose to only market usable capacity to set honest and reasonable expectations for our customers. The Titan XXL tank also features minimal hang down below the bottom of the stock tank (approximately only 2.5" lower).
Installation is a breeze - no fabrication or cutting required. This tank is a direct fit, bolt-in application, making it the perfect upgrade for your Ram 2500 or 3500 pickup.
