It all depends on how much fuel they go though. If its a truck stop that has a lot of business, It would'nt be long. But a local gas station, I would wait a little longer. Say 2-3 weeks. Just my opinion though....

the fuel is filtered out of the ground and there going to the tier 2 pumping equipment which has monitoring equipment to see moisture, solids content in fuel. i work on the electrical end of alot of thees upgrades. fuel will come out cleaner than before all the tanks, pipe and fittings are all sealed before they get installed. and even if something got in there the filter is at the pump.

If there were any sediment in a brand new tank (not likely) don't you think that it would be stirred up by the filling of the same tank with that 4 inch thick hose that the tankers use?

Nothing to worry about. I installed Xerxes tanks and Owens/Corning fiberglass tanks for 6 1/2 years. For my family who's been installing underground tanks for over 50 years. Yes, water is used in tanks as "ballast" until the slab is poured above them ( to prevent them from floating out of the ground). Then the tanks are pumped dry and filled w/ fuel. Most of the water that shows up in the tanks comes with the fuel in the tanker. After it's dropped, the water all sinks to the bottom, as it is heavier then fuel. The submersible pumps are usually set at least 8" above the bottom of the tank. There are floats in the tank that measure both water and fuel level in each tank. When the water reaches a pre-determined level, it sets an alarm off in the store. Then they send someone like me, to pump it out.
If by chance, water does get pumped up into the product dispenser, filters take care of it. If there is enough water in the system, it will clog up the filter stopping fuel from dispensing. I would never say never. But odds are, you'll be fine. Depending on where you get your fuel, you'd be a lot more scared about what the fuel itself actually looks like.
Buts that's another long story for later.....
Sorry for rambling!
