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.

Third-party programming tools and software are independent of, and not guaranteed by, TITAN Fuel Tanks™.

Additional Details

Optional kit (9900057) will allow the tank to be used as an auxiliary tank to feed a stock rear, after axle tank.

Optional filler neck assembly is also available. (P/N 9900025)

Our mid-ship, replacement fuel tanks utilize the truck’s stock/OE sending unit. An aftermarket or upgraded sending unit is not needed or required in any way.

In rare cases, some aftermarket/upfit C&C products may cause interference with the Titan Tank. It is best practice to ensure other aftermarket/upfit items will not interfere with the Titan Tank before purchasing.
