Using this VP Racing fuel jug is easy. First, select your desired color. You can add the filler hose spout and adapter for smooth fuel pouring. When filling, just check the gallon or liter markings to know how much fuel you're adding. As for handling, be careful because of its size. Since it's large, you might need some extra space to store it. When it comes to maintenance, keep it clean and dry. Make sure to check the spout and adapter regularly for any signs of wear or damage. And remember, due to its size, there's a shipping surcharge when you order it.
