The fuel transfer tank is a tank designed to hold additional fuel, often beyond what was intended by the original manufacturer.
It can then be transferred to the main tank, or depending on the design, the engine will draw fuel directly from there, hence the name, fuel transfer tank.
For those who travel long distances, especially in the less populated areas, having enough fuel can be the difference between getting to your destination and being stuck in the middle of nowhere.
There are many challenges faced when traveling long distances. Some of these include higher prices in more remote areas, harsh or even unexpected weather changes. Being prepared is the way to beat those forces trying to hold you back.

2. How Is A Fuel Transfer Tank Regulated?
As you know everything in the USA is regulated by any one, or a combination of regulatory agencies. These include the Department of Transportation (DOT) and the Environmental Protection (EPA) and a host of other state and local agencies. These agencies are tasked with ensuring the fuel transfer tank meets and even exceeds the standards set by VESC-22 regulations.
