The Titan Fuel Tanks 9900057 Cab and Chassis Auxiliary Kit is a vehicle-specific conversion kit for using a TITAN Cab and Chassis midship tank as an auxiliary system. It is designed to feed the stock rear after-axle tank on listed Dodge Ram and Ram 3500, 4500, and 5500 chassis applications.

The kit gives the auxiliary system the required control and transfer components in one package. It includes the sending unit, auxiliary pump, controller, and all necessary wiring, helping turn the TITAN midship tank into a managed auxiliary fuel setup instead of a loose collection of separate parts.

This USA-made kit supports 169.3 in, 193.3 in, and 203.8 in wheelbase applications and is backed by a limited lifetime warranty. It is intended for the listed cab and chassis applications, not as a standalone replacement fuel tank.

The Titan Fuel Tanks 5015100 is a 100 gal rectangular in-bed diesel transfer tank made from military-grade cross-linked polymer. It uses a fully baffled design, robust ribbing, strength channels around the transfer-pump fitting, and a 2 in NPT fitting for common transfer pumps.

The 100 gal capacity gives work trucks and long-distance users a larger onboard diesel transfer supply without the corrosion and condensation issues common with metal tanks. The polymer body is built to be tougher than steel and more durable than aluminum, with bottom support designed to help keep the pump drawtube in place.

The tank meets DOT and FMCSA Title 49 requirements, is made in the USA, and is backed by a limited lifetime warranty. It includes a locking cap and mounting hardware, but does not include a pump.

The Titan Fuel Tanks 5015090 is a 90 gal L-shape in-bed diesel transfer tank made from military-grade cross-linked polymer. It uses a fully baffled design, robust ribbing, molded-in toolbox-platform support, and a 2 in NPT fitting for common transfer pumps.

The L-shape design keeps room available for a toolbox and leaves clearance for 5th wheel and gooseneck trailer hitches. The polymer body does not rust, corrode, degrade, or build condensation like metal tanks, while strength channels around the pump fitting add rigidity where transfer-pump loads matter.

The tank meets DOT and FMCSA Title 49 requirements, is made in the USA, and is backed by a limited lifetime warranty. It includes a locking cap and mounting hardware, but does not include a pump.
