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

• 2011-2026 Ford Trucks:
Use the Titan Tech programmer (available directly from TITAN Fuel Tanks) to update the DTE in seconds.
• 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™.

For model years 2007-2026.

For Ram/Dodge Cab & Chassis Trucks 60”, 84", 108" & 120” CA trucks.

•    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.

CA or Cab to Axle refers to the distance/length in inches between the back of the cab and the center of the rear axle.

YES: Great! All you need to purchase is a Titan tank. You don’t need to worry about anything else on this page.

NO: You’re going to need a few extra parts. Let’s help you get everything sorted.

No. The Ram trucks come with the DEF tank installed out of the way of the midship tank.

As an Auxiliary Tank: Your Titan midship tank will be installed where the stock midship would be located. The fuel in the tank will be transferred into your stock aft-axle tank. This is similar to an auxiliary in-bed tank system.
You'll also need to purchase:

• Titan Ram Chassis Auxiliary Kit - PN: 9900057 (Comes with a sending unit, auxiliary pump, controller, and all necessary wiring.)
• A fill neck for your new tank. (Titan offers a Universal Filler Neck Kit - PN: 9900025)

By deleting my aft-axle tank and using the Titan tank as a stock midship: While deleting the aft-axle tank is a common enough practice, we have found that Ram prefers to work with registered upfitters or dealers for parts such as fuel lines. We highly recommend working with a registered upfitter in your area with experience doing these modifications.

• We recommend replacing your existing fuel lines with lines designed for the Ram midship tank. While fuel line modifications are possible, DO NOT modify your fuel lines without a thorough understanding of the process.
• The aft-axle sending unit is tall enough to work with our midship tank, but the float arm points the wrong direction. This requires the sender to be clocked at a different angle and requires the orientation tab to be modified. Please be aware that these sending units are made from a brittle plastic that cracks easily.
• Rather than trying to rearrange or adjust the electrical harness, we recommend extending the wires in the electrical connection.

As a stock Ram tank by reconfiguring my truck to have stock dual tanks: This installation is extremely complicated. Please be aware that this will essentially require you to completely replace all fuel lines, sending units, and the entire electrical harness for your vehicle. If your vehicle requires a dual stock tank set-up, we HIGHLY recommend purchasing a truck that comes with dual stock tanks. That method would only require you to swap out the stock midship for the Titan midship tank.
