Q: Could this not be used with gasoline as a transfer and the option to attach to your actual fuel tank? I just dont understand why it only says diesel. I noticed the majority of others online can do both. I would prefer to buy and pick up from you guys.

  • A: No, this tank is only rated for diesel fuel and other class 2 flammable liquids, such as kerosene or oil. It is not certified for use with gasoline. While it can be plumbed directly into a vehicle's existing diesel fuel system, it is specifically tested and certified for diesel fuel only.
