Option 850 - Additional Fuel

Could someone in the know tell me what this is? Larger fuel tank? Jerry can?

It was an option ticked on my E28.

Probably meant that they put a gallon of unleaded in it before they delivered it.....

I am pretty sure it was a slightly larger fuel tank. I know on some E34's it was also an option.
