Titan Fuel Tanks 2020 - 2026 GM Silverado / Sierra 2500/3500 Duramax Crew Cab Short Bed 56 Gallon XXL Mid-Ship Fuel 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.

Issue: Fuel gauge drops to empty after Initial Install and during normal operation.

Explanation: GM trucks have the ability through programming and monitoring to know exactly how much fuel is in the tank, as well as fuel consumption based on miles driven and fuel economy. Any large capacity fuel tank causes the float to move slower than the computer thinks is acceptable. When the computer sees this, it will run a system check and drop the fuel gauge to empty. When the fuel level comes off full, the gauge should return to the correct position after restarting the vehicle.

Solution: Although we were told early on that trucks have fixed themselves after several tanks of fuel when following a specific process, we are no longer able to confirm this or any other permanent fix for this issue. If this is a concern for you, we recommend using an aftermarket digital monitor to confirm accurate fuel level when this occurs.
