TRANSFER FLOW

Since 1983, Transfer Flow has set the standard for professional-grade fuel tank systems in the United States. Every tank we design, engineer, and manufacture is American-made, reflecting our unwavering commitment to quality, durability, and precision craftsmanship. Whether you need to extend your truck’s fuel range, add a reliable in-field refueling solution, or upgrade to a high-capacity replacement tank, Transfer Flow delivers safe, legal, and dependable solutions you can trust.

Our in-bed auxiliary fuel tanks provide additional fuel capacity without compromising reliability or bed space. Built from rugged aluminized steel, they are engineered to withstand demanding conditions and years of heavy use. DOT-compliant refueling tanks are available in multiple sizes and include convenient features such as a 12-volt fuel pump and cab-mounted power switch, making refueling fast, safe, and efficient—no matter the job site.

For those looking to maximize range without sacrificing performance, our replacement fuel tanks are engineered to fit precisely in the stock tank location while offering larger capacity. Retrofit filler neck kits are available for a wide variety of vehicles, ensuring smooth installation and factory-quality fit.
