13. Moisture Laden?

What state are you in?
Every station in Illinois has to have tank sensors detecting any water above the settling sump.
If the level in the sump exceeds 90%, the alarm goes off & the station has to shutdown until the service can come by to pump out the sump.
Since water is insoluble in gasoline, only water at the bottom of the tank matters.
Also, in most of the country, there is no "rot gut" gasoline. It is all refined to API & DOE standards.
Discount gas doesn't have all, or as much of, the additives added at the terminals. But, it's not off-quality product.
It's illegal to sell out if specification gasoline at the refiner or wholesale level.
