This is the Team Associated 500cc Factory Team Pro Nitro Fuel Bottle. With 500cc volume, this bottle will fill a 125cc buggy fuel tank four times before you need to add more fuel, allowing you to focus on more urgent pitting tasks. A rubber cap helps reduce the risk of contamination and prevents evaporation. Bottle features graduated marks that measure from 50cc to 500cc in 50cc increments. The long, curved aluminum spout allows you to easily reach the fuel tank opening.
