From ABYC web site...

Q. What are the limitations for the use of stainless steel in fuel tank applications? A. Stainless steel can be used for both gasoline and diesel fuel tanks. However, for gasoline tanks, the tank cannot be any larger than 20 gallons and it must be cylindrical with domed ends. There are no restrictions on size for diesel tanks.

Sounds like that tank would be OK for a diesel application, not gas.
