What Transfer Flow does
Transfer Flow, Inc. is a privately held American manufacturer founded in 1983 and based in Chico, California, specializing in aftermarket fuel tank systems for pickup trucks and commercial vehicles. The company designs, engineers, and manufactures in-bed auxiliary fuel tanks (37 to 100 gallons), DOT-approved refueling tanks (20 to 109 gallons), replacement midship fuel tanks, and patented fuel tank/tool box combination systems, all built from U.S.-sourced 12- and 14-gauge aluminized steel. Its proprietary TRAX 4™ operating system provides computer-controlled automatic fuel transfer between auxiliary and main tanks, with a companion smartphone app delivering real-time fuel-level and distance-to-empty monitoring.
The business operates through a multi-channel go-to-market model: direct-to-consumer sales via the TransferFlow.com e-commerce storefront (including 'Buy Now, Pay Later' financing), a national certified installer network with a 'Find an Installer Near You' tool, authorized dealers, and an OEM Products division that supplies custom and white-label fuel tank solutions to vehicle manufacturers and commercial upfitters. Products are legally compliant for transport and dispensing of gasoline, diesel, and kerosene in all 50 U.S. states under DOT Special Permits and CARB Executive Order approvals, and are warranted for up to six years. Unit pricing spans approximately $780 for entry-level diesel refueling tanks to over $3,700 for large tank/tool box combo systems.
Transfer Flow serves individual truck owners seeking extended driving range for towing, off-road, and overland use, as well as commercial fleet operators requiring mobile refueling capabilities for equipment in remote locations, and OEM vehicle manufacturers and upfitters requiring custom fuel-system configurations. Leadership consists of CEO Lisa Johnson and Founder/Senior Engineer/Chairman Bill Gaines. The company is independently owned with no disclosed institutional investors, parent company, or subsidiaries, and employs more than 90 North State residents at its single Chico manufacturing facility.
