@wilatemodel - Yes, absolutely tank containers can be used for storage of many products, including fuel. Most have stainless steel tank barrels and stainless steel valves, and will provide decades of service. Sometimes fuel storage tanks are governed by local regulations, so first check with your local fire marshall or other authority about what restrictions (if any) apply; such as secondary containment, etc. Thanks for watching.
@MilbyDragonBlade - Well, then you probably have the ultimate budget; and so Yes we can help you. Have one food-grade tank in stock ex-Houston, available for $18,500 and ready to go...
