2007-2024 Cummins Cab & Chassis Replacment Tank (7030XXX)

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 - Part # : 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 - Part # : 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. It is highly recommend working with a registered upfitter in your area with experience doing these modifications.

• It is recommended to replace 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.
