VEVOR 16 Gallon Fuel Caddy, 7.8 L/min, Portable Gas Storage Tank Container with Rubber Wheels, Gravity-flow Mode, Fuel Transfer Storage Tank for Gasoline Diesel Machine Oil Car Mowers Boat Motorcycle

Can this be used to store vegetable oils and alcohol.

How long is the hose?

Can the tank be hung by handle to elevate it?

Is this for 2 16 gal tanks or just one.

So if it is gravity fed, does that imply the lowest point of the caddy must be higher than the receiving vehicle refill port? A video showing the set up and operation would be helpful to understand the concept.
