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 long-term 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.
