Transfer Flow Announces TRAX 4 Fuel Manager

Fuel’s Errand

The Transfer Flow TRAX 4 is a computer-controlled, fuel management system that transfers fuel from a Transfer Flow auxiliary fuel tank to a pickup’s main fuel tank. TRAX 4 comes with our auxiliary fuel tank systems, including their auxiliary tank and tool box combos. Based on the capacity of a pickup’s main fuel tank and the capacity of the Transfer Flow auxiliary fuel tank, the TRAX 4 system will transfer fuel at pre-determined levels while the vehicle is in operation.

Want to know the status of your on-board fuel systems? Simply download the TRAX 4 app to your smart phone and enter your vehicle and fuel system information. In no time, you’ll be able to monitor your pickup’s fuel capacity. During fuel transfer, the message “Pump On” will be displayed. You also have the option of displaying either the gallons or the percentage of fuel in each tank. The app is available for Apple IOS and Android (version 7 or newer).

TRAX 4 comes with a manual fuel transfer button. You can use the button to manually transfer fuel. When the button is pressed, and the main tank is below 85%, the pump will turn on for a five-minute cycle or until the main tank’s fuel capacity is at 85% or above. As a safety feature to prevent overfilling, the button will not do anything when the main tank is over 85%. Pressing the button again will turn off the pump. The red light around the button indicates when the fuel pump is on, and fuel is being transferred.

ABOUT Transfer Flow®

Transfer Flows story began in 1983 in the beautiful and historic town of Chico, California, when former General Motors engineer Bill Gaines, founded the company as an OEM fuel system supplier for the motorhome and travel trailer industry. TFI quickly expanded into the mobility, work body, and mainstream automotive industries, and by 1994 the company relocated to a 35,000 square-foot manufacturing facility as demand continued to grow. Six years later, a 20,000 square foot building was built on an adjacent 3-acre parcel, and finally in 2008, a 15,000 square-foot warehouse was also added.
