No maker of any gas or diesel fueled motor would ever put the pickup point at the very very bottom of the fuel tank, or there'd be constant troubles, even from owners of brand new machines, as they took in impurities and water.
Yes, there's a molded depression in the tank bottom where the fuel pump basket sits. But it's not the lowest point. I think you'll find the tank runs off to still lower points. And the pickup itself, that 1"x1/2" down-facing grilled port, doesn't take from the floor but a bit up from it.
My most full and recent personal experience of this comes from a 9000 so it needs a C900 owner to test and report here. And maybe ccb is worried enough about water to do it. I'd suggest, car parked on level ground, disconnect the fuel line banjo bolt at front of fuel rail, set bolt and both washers aside, and carefully thread the plastic line, without kinking, back and down under the manifold and starter, sticking out the front. Then remove the air cleaner and put a big jug there (5 gallons will fit) and stick the line in it and trigger the fuel pump.
Keep changing jugs out as they fill (shut off the power) till the pump stops putting out fuel. Pull trunk floor, tin cover, and disconnect wiring and fuel lines and undo the collar and pull the pump out of the tank. (No smoking.)
Then with gas-proof rubber gloves on, using a flattened soup can start bailing liquid out of the tank and put it into a container that will let you inspect it and measure what you get. When the can stops getting much in it, switch to a clean cotton rag and keep sopping liquid out and wringing it into your container. Chase down the last traces of things, and any dirt, with paper towel, dampened if need be to pick up any silt or sand.
You can put all recovered liquid into say a gallon milk jug with a drywall screw stuck into a lower corner. The water will sit at the bottom (you'll see it) and you can pull the screw and let water drain off and recover the usable fuel, leaving just a tiny trace of gas with the tiny bit of water you can't drain.
There's also the fuel pump basket to drain (tip it upside down) and the fuel filter, which is a coffee-can size trap that sits sideways and if there was a lot of water in your tank, so much you were actually getting some delivered to the fuel rail, it will be filled to nearly halfway up with water that won't go away except maybe over time, and can contaminate your fuel. So it needs to be carefully disconnected (don't kink the lines) and removed and drained and dried or replaced.
There could also if water indeed made it to the fuel rail be water in the pressure and return fuel lines so they need to be blown out. The fuel rail itself may also concern you but if it still has any water in it it will self purge and if any makes it back to the tank it will be but a trace.
