Funny we're having this discussion. I wanted to post this now because I JUST talked to my storage tank contractor and he's replacing the sump lids on some of the storage tanks at one of our fuel stations. Why? The sump lids weren't tight, the sumps filled with water, and whenever the fueling contractor filled the tanks, all that water was dumped into the tanks. How much? Try 150 gallons. Now, these are 15,000 tanks (3 of them), so there's about 50 gallons in each 15,000 tank. That's about 1.5" of water at the bottom of one of these tanks, and the suction pipe is usually about 6" off the very bottom of the tank. Normally, not a problem with gasoline...the water sits at the bottom, gets sucked out periodically, and you get on with business. But if you have a higher percentage of ethanol than allowed (maybe they get something like E25 for some reason), and his tanks are leaky, you could very easily make a mess of your fuel, and potentially mess up a lot of customers' fuel systems.
