This Titan replacement tank is designed for Ram 3500 Cab & Chassis models and is built around the factory setup, making it a practical option for owners who want a vehicle-specific solution without unnecessary complication.

That helps retain proper fuel gauge operation while keeping the installation closer to factory design. There are also a couple of optional extras depending on how the truck is set up. An optional kit is available to allow the tank to be used as an auxiliary tank feeding a stock rear after-axle tank, and an optional filler neck assembly is also offered separately.
