You can purchase bulk fuel tanks from several manufacturers and retailers, including Tractor Supply Co, Smart Tank, JME, Northern Tool & Equipment and Bulk Fuel Sales. These tanks hold anywhere from 37 gallons to 20,000 gallons.
A 37-gallon transfer tank fits in the back of a pickup truck to provide fuel for on-site refueling of gasoline-powered machinery. These transfer tanks provide storage for gasoline for yard equipment, construction machinery and vehicles with small engines.
Large bulk fuel tanks, such as models that contain 20,000 gallons, serve as a way for companies to refuel fleets of cars and trucks without going to a gas station. Transfer tanks and bulk fuel tanks contain pumping mechanisms that safely move the fuel from the large tank to the vehicle's tank.
