Upgrade to the 40 Gallon* Extra Heavy-Duty Frame Mounted After-Axle Replacement Tank today and experience the difference that quality craftsmanship can make.

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.
