Go further, tow longer, and fuel up on your own terms. Titan Fuel Tanks is revolutionising the industry again with the new Gen 7 XXL Replacement Fuel Tank. Adding a massive 21 gallons over your stock 31-gallon tank, this 52-gallon upgrade gives you the ultimate peace of mind for heavy towing, cross-country adventures, or skipping the pumps during your daily commute.

Constructed from Titan’s legendary High-Density Cross-Linked Polyethylene (XLHDPE), this tank offers unmatched, heavy-duty durability backed by an industry-leading Lifetime Warranty.

Why Choose the Titan XXL Gen 7?

• True 52-Gallon Usable Capacity: Thanks to an exclusive low fuel trap design, every drop is usable. We only advertise what you can actually drive on—honest capacity for honest expectations.

• Maximum Ground Clearance: Carefully engineered to hang just 2 inches below the bottom of your stock tank.

• Hassle-Free Installation: 100% direct-fit, bolt-in application. No fabrication, cutting, or drilling required. Includes black-coated, galvanized steel mounting straps.

• Accessory Friendly: Will not interfere with powered steps, air bag systems, or most other aftermarket accessories.

The Gen 7 Advantage: New Optional Upgrades

Maximise your truck’s versatility with Gen 7’s three innovative, optional add-ons (sold separately):

• Fast Fill Vent Kit: Experience hassle-free fueling at high-flow commercial truck stop pumps.

• Universal Pickup Tube: Fully compatible with high-pressure, aftermarket fuel systems.

• Transfer Pump Kit: Turn your truck into a mobile fuel station and easily fill up other vehicles or equipment directly from your XXL tank.

Strict Fitment & Compatibility

• Fits: 2025+ RAM 2500 and 3500 Crew Cab, Short Bed with Cummins Diesel engine.

• Drivetrain: 4×4 trucks ONLY. (Will NOT fit 2WD models).

• Bed Type: Traditional pick-up short beds ONLY. (Will NOT fit Cab & Chassis models).

• Factory Tanks: NOT compatible with trucks ordered from the factory with the optional 48/50 gallon RAM tank.

• Fuel Systems: Uses your truck’s stock/OE sending unit, but is also fully compatible with aftermarket lift pumps like Fleece, AirDog, and FASS.

Fuel Gauge & Distance-to-Empty (DTE) Info

• Your Fuel Gauge Will Remain Accurate: Because your new Titan Tank holds significantly more fuel, your in-dash gauge will simply stay on “Full” much longer before it begins to drop.

• Updating Your Range / DTE: Reprogramming your Distance-to-Empty (DTE) is not required for the tank to function perfectly. However, if you want your dashboard’s range calculator to reflect the massive new 52-gallon capacity, you can update your truck’s computer.

• For RAM Trucks: Customers typically use AlfaOBD, an affordable, RAM-specific software that easily updates the vehicle’s computer for the increased capacity without the need for expensive, mail-in programmers. (Note: Third-party programming tools are independent of, and not guaranteed by, TITAN Fuel Tanks).
