Titan Fuel Tanks 2019 to 2026 GM 1500 Crew Cab Short/STD Bed 3.0 Diesel 43 Gallon

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. Titan's Gen 7 tanks are designed to meet the needs of diesel truck owners who demand more from their fuel tanks. These tank accessory kits are sold separately.

The 43 Gallon Extra Capacity Mid-Ship Replacement Fuel Tank is designed specifically for 2019-2026 GM 1500 4x4 pickups with Crew Cabs, Short or Standard Beds, and Duramax engines. Whether you're towing heavy loads, embarking on cross-country adventures, or simply navigating daily commutes, the extra capacity provided by a Titan XXL Tank gives you the confidence and peace of mind to go the distance, no matter where the road takes you.

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 43 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 1.5” 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 GM 1500 Duramax pickup.

Fuel Gauge & Distance-to-Empty with a TITAN Tank

• Fuel Gauge: Your in-dash fuel gauge will remain accurate. Because your TITAN Tank holds more fuel, the gauge will simply stay on “Full” longer before beginning to drop
• Distance-to-Empty (DTE) / Range: Programming the DTE is not required, as your fuel gauge will continue to read accurately. However, customers who want their Distance-to-Empty (range) display to reflect the new tank capacity can update it on most trucks. Until programming is completed, the DTE reading may be inaccurate.
• When it comes to programming, Titan keeps it simple, there is no need to have us ship you an expensive programmer that you send back. We have our own Titan Tech programmer available for some make and models, while other truck models can be done with very affordable and easy to use software

Programming Options

• 2025-2026 Ford Trucks: Use ForScan, a Ford-specific software that allows the vehicle computer to be adjusted for the increased TITAN tank capacity.
• 2017-2024 Ford Trucks: Use the Titan Tech programmer (available directly from TITAN Fuel Tanks) to update the DTE in seconds. ForScan software may also be used.
• 2011–2016 Ford Trucks: Use the Titan Tech programmer (available directly from TITAN Fuel Tanks) to update the DTE in seconds. ForScan or Ford dealership IDS software may also be used.
• 2019-2024 RAM Trucks: Use AlfaOBD, a RAM-specific software that allows the vehicle computer to be updated for the increased TITAN tank capacity.
