American-Made, Aftermarket Fuel Systems
Transfer Flow started in 1983 in Chico, California. Former General Motors Engineer Bill Gaines founded the company as an OEM fuel system supplier for the motorhome and travel trailer industry. Transfer Flow quickly expanded into the mobility, work truck, and mainstream automotive industries.
Customers who drive their trucks daily appreciate the freedom and efficiency that additional onboard fuel provides. Whether you’re running errands around town or taking long road trips, a Transfer Flow fuel system adds ease and reliability to your travels. Replacement fuel tanks maximize mileage without taking up space in the truck bed, while in-bed auxiliary tanks automatically transfer fuel to the stock tank or replacement tank using the patented TRAX 4 Auto-Trans operating system.
