Truck & SUV Tanks

Trucks and SUVs are built for work, adventure, and the long haul. When your factory fuel tank develops a leak, suffers corrosion, or simply can't carry enough fuel for your next remote expedition, we have the replacement or upgrade you need. Our truck and SUV gas tank selection covers a wide range of domestic and import platforms — from full-size pickups to classic 4x4s to heavy-duty work rigs.

Each tank in our catalog is manufactured to strict quality standards, using materials that are compatible with modern fuel blends including E10 and E15 ethanol formulations. Tanks are designed for direct fitment with correct strap mounting positions, sending unit openings, and fuel neck placement, making installation straightforward whether you're a DIY mechanic or a professional shop. Many options feature enhanced skid protection for off-road applications.

Select your year, make, and model to find the right replacement or upgraded tank for your truck or SUV.

Frequently Asked Questions

What are the benefits of installing a high-capacity replacement or auxiliary fuel tank in a truck?

High-capacity fuel tanks from brands like Transfer Flow and Titan Fuel Tanks significantly extend your driving range by replacing the small factory tank or adding a secondary auxiliary unit. These systems allow diesel truck owners to bypass expensive fuel stops during long hauls and provide the extra volume needed for towing heavy trailers or overlanding in remote areas.

Will a Transfer Flow or Titan fuel tank fit my specific Ford, Chevy, or Ram diesel truck?

Most aftermarket fuel tanks are engineered for specific vehicle applications, such as the Transfer Flow 50 Gallon Auxiliary Tank for Ford F-250 or the Titan 40 Gallon Sub Tank for Ram 2500. Compatibility often depends on your truck's bed length, engine type, and whether it is a chassis cab or a standard pickup bed, so always verify your specific model year and wheelbase before purchasing.

How do I choose between a midship replacement tank and an in-bed auxiliary fuel tank?

A midship replacement tank like the Transfer Flow 40 Gallon Tank for Chevy Silverado replaces your stock unit underneath the vehicle to keep your bed space clear. In-bed auxiliary tanks offer much higher capacities and often include refueling pumps, making them ideal for heavy-duty users who don't mind sacrificing a portion of their truck bed for maximum fuel range.

Are aftermarket poly fuel tanks better than aluminized steel tanks for off-road SUVs and trucks?

Titan Fuel Tanks utilizes high-density cross-linked polyethylene which is nearly indestructible, rust-proof, and lighter than metal, making them perfect for off-road environments. Transfer Flow uses aluminized steel for superior strength and integrated baffling, which is often preferred by towers who want a heavy-duty, crash-tested solution that meets strict emissions standards.

What should I check regarding fuel sensor compatibility when upgrading my truck's gas tank?

Before buying, ensure the aftermarket tank is designed to work with your vehicle's factory sending unit so your fuel gauge remains accurate. Many premium tanks from Transfer Flow and Titan include specialized components or digital controllers to integrate seamlessly with your OEM electronics and prevent dashboard error codes.
