Built for Extreme Conditions
The Titan Fuel Tanks XXL receives its construction from military-grade cross-linked polymer which forms the base material of all Titan tanks but exists in an expanded form for maximum capacity. The material weighs less than steel while providing five times the strength of high-density polyethylene to create an almost unbreakable tank for actual use.
The material remains resistant to rust and corrosion and will not experience cracking or deterioration. The tank material absorbs all types of impacts which would damage metal tanks while it resists chemical substances and salt exposure and operates effectively in extreme temperatures. The Titan XXL tank operates without failure throughout all seasons from Montana's cold winters to the Mojave Desert's hot summers.
The tank undergoes multiple quality checks and pressure tests to verify its leak-proof operation. The tank features built-in baffles which help maintain stability when carrying large fuel amounts while preventing liquid movement. The tank material features a smooth interior surface which minimizes water accumulation and microbial growth.
Engineered for Perfect Fit and Function
The Titan XXL tank system functions as a direct substitute for standard factory tanks which fit various heavy-duty trucks including Ford Super Duty, Ram HD, and GM HD models. The installation process uses all original factory components for fuel pumps, sensors, and mounting hardware to achieve a simple setup.
The tank design follows the truck frame and bed shape to preserve both height clearance and weight distribution balance. The tank system connects to the truck computer system and fuel gauge system for accurate readings and reliable operation after installation.
Titan engineers each XXL tank model to provide complete clearance for gooseneck and fifth-wheel truck configurations along with their associated bed supports and crossmembers. The tank system allows you to maintain both towing capacity and fuel storage capacity without any trade-offs.
Smarter Design, Stronger Performance
Titan Fuel Tanks is known for innovation, and the XXL line takes that to another level. Each tank features an exclusive low-fuel trap design that ensures nearly every drop of fuel is usable. The rollover safety valve system adds extra protection without restricting flow, while precision venting prevents vacuum lock and refueling backflow.
A thick, powder-black finish shields the tank from UV exposure, and all fittings are molded in, not glued or welded, eliminating weak points. The result is a tank that’s not just larger — it’s engineered to last the lifetime of your vehicle.
More Range Means More Possibility
The daily experience of Titan Fuel Tanks XXL owners involves driving between 800 and 1,000 miles before needing to refuel. The extended fuel range enables cross-country haulers to spend less time waiting at truck stops. The extended fuel range enables weekend travelers to explore alternative routes without running out of fuel.
The ability to refuel at locations with the lowest diesel prices leads to substantial financial benefits. The XXL tank helps drivers save money through decreased refueling expenses and reduced time spent at fueling stations according to numerous reports.
The Titan Fuel Tanks XXL provides users with more than just ease of use because it gives them complete command over their journey. The extended fuel range enables drivers to select their own stopping points and follow their desired route without any restrictions.

The Titan Fuel Tanks XXL function as factory replacements so you can preserve your vehicle's original performance and maintain all required emissions standards.
