Product Description
The ATI TTL50 47 Gallon L-Shaped Refueling Tank is built for truck owners, contractors, farms, fleets, and equipment operators who need a compact DOT-approved aluminum refueling tank that still leaves valuable bed space available. Its L-shaped profile is engineered to fit beneath most standard crossover or chest toolboxes, making it an excellent choice when you want secure storage above and dependable fuel handling below. Built from rugged diamond plate aluminum and fully baffled for strength and slosh control, the TTL50 is ready for serious work in the field, on the ranch, at the jobsite, or anywhere mobile fuel access matters.
ATI designed the TTL50 for legal refueling use under its DOT special permit, giving operators a practical way to carry and dispense approved fuels without stepping up to a bulkier rectangular tank. The dual 2-inch NPT bungs, 3/8-inch NPT drain, pressure- and leak-tested construction, and hold-down brackets make it a strong option for a clean, professional install. Whether you are fueling equipment, remote machinery, diesel trucks, or mixed-use commercial assets, the ATI TTL50 delivers the durability, fitment flexibility, and real-world usability that help separate a serious setup from a compromise build.

FAQ
Is the ATI TTL50 a DOT-approved refueling tank?
Yes. ATI markets the TTL50 as a DOT-approved refueling tank built under its special-permit framework for legal refueling applications when properly installed and used.
Will the ATI TTL50 fit with a crossover toolbox?
That is exactly what the L-shaped design is intended for. The lower section is designed to sit under most standard crossover or chest-style toolboxes, but you should still measure your bed and toolbox before ordering.
What fuels can be used in the ATI TTL50?
ATI lists compatibility with gasoline, diesel, kerosene, methanol, and aviation fuel under its approved refueling-tank use case.
Is the ATI TTL50 baffled?
Yes. The tank uses fully welded internal baffles to reduce slosh and improve strength during transport and use.
Does the ATI TTL50 come with a pump?
No pump is included with the standard tank. It is designed to work with transfer pump setups, and its dual 2-inch NPT bungs provide flexibility when planning your installation.
What should I watch for when measuring fitment?
Check overall tank length, width, and height, then account for the mounting tabs and the extra height added by the fuel cap. Toolbox lid clearance and bed rail spacing should be confirmed before purchase.
