Spec'd Correctly Before It Ships

The wrong fuel tank for your Tundra fleet means downtime, return freight, and a mechanic who can't finish the job. We run a free pre-offer spec review on every order — verifying your model year, cab configuration, and fuel type against the Transfer Flow fitment matrix before the tank leaves the factory. If you have a Flex Fuel Tundra, we flag it immediately because this 46-gallon system is not compatible. No guesswork, no return freight claims, no wasted shop time. The tank that arrives is the tank your truck needs.

Industrial-Grade, Heavy-Gauge Steel That Outlasts the Road

Industrial-Grade, Heavy-Gauge Steel That Outlasts the Road

This tank is formed from 12-gauge ReliaSteel®, a high-yield U.S. aluminized steel built to handle the vibration, impact, and corrosive conditions that destroy lesser tanks. Internal baffles reduce fuel sloshing to maintain stable weight distribution whether your fleet is running highway miles or rough job-site access roads. The in-frame mounting position keeps the tank protected within the Tundra's rail structure, not exposed to road debris or ground contact. This is industrial-grade fuel storage designed for trucks that actually work.

Six-Year Unlimited-Mile Coverage With Every Tank

Six-Year Unlimited-Mile Coverage With Every Tank

Transfer Flow backs this system with a 6-year, unlimited-mile warranty — not a prorated decline that leaves you covering the cost after year two. For fleet operations running multiple Tundras across long hauls and daily routes, that coverage matters. The highly engineered emission system reduces hydrocarbon release to keep your trucks compliant with emissions standards, and the complete hardware package means your installer has everything needed on the first attempt. No chasing missing fittings, no secondary orders, no downtime between removal and replacement.

Compatibility

Verify your truck matches these conditions before ordering. Not compatible with Flex fuel Tundras.

“We run eight Tundras across our job sites. Swapped two over to the 46-gallon Transfer Flow tanks and cut our fuel stops in half on remote sites. Install was clean — everything was in the box. Tank Vault confirmed our 2019 CrewMax fitment before we ordered, which I appreciated.”

Frequently Asked Questions

Yes. This 46-gallon Transfer Flow system fits 2007–2021 Toyota Tundra Double Cab and CrewMax trucks in both short bed and long bed configurations. The tank mounts inside the frame rail as a direct replacement for your factory unit. Not compatible with Flex Fuel Tundras — confirm your fuel type before ordering. Tank Vault runs a free pre-offer spec review to verify fitment against your specific truck before shipment.
Direct fit. This Transfer Flow tank system replaces your factory fuel tank using the in-frame mounting location with all components included for installation. No fabrication, no custom brackets, no adapter harnesses. Your installer removes the OE tank and installs this 46-gallon system using the provided hardware. If you want us to verify compatibility with your specific configuration before purchase, request a free pre-offer spec review.
Flex Fuel Tundras use a different fuel system architecture with components that are not compatible with this Transfer Flow 46-gallon gasoline tank. Installing a non-Flex Fuel tank on a Flex Fuel vehicle creates fuel delivery and emission system conflicts. Transfer Flow manufactures separate part numbers for Flex Fuel applications. If you are unsure whether your Tundra is Flex Fuel, check the badge on the tailgate or the VIN — or contact Tank Vault and we will help you confirm.
ReliaSteel® is Transfer Flow's high-yield U.S. aluminized steel, engineered for fuel tank applications where vibration resistance and corrosion protection are critical. The 12-gauge thickness provides substantial wall strength compared to thinner aftermarket tanks that can develop stress fractures over time. Aluminized steel resists rust from both internal fuel exposure and external road conditions. For fleet trucks running daily routes and heavy loads, this material choice directly affects service life.
Transfer Flow replacement tanks are built to order and typically ship within a few weeks of order placement. Lead times vary based on production schedule. If you have a specific deadline — a fleet rollout, a seasonal operation start, or a shop scheduling window — contact Tank Vault before ordering. We coordinate directly with Transfer Flow to confirm current production timelines and arrange LTL freight to your location. Ships free to your specified delivery point.
Transfer Flow manufactures in the U.S. using 12-gauge ReliaSteel® aluminized steel, includes internal baffles for fuel sloshing control, integrates a factory-engineered emission system, and backs every tank with a 6-year unlimited-mile warranty. Lesser tanks use thinner material, omit baffles, and carry limited warranties that prorate quickly. For fleet operations where a tank failure means a truck down and a job behind schedule, the build quality difference is the point.
