BMW R850R Fuel Pump, Tank, Water in the Gas
Here's the inside of the tank with the fuel pump removed. The inside of the tank is painted red. Notice the brownish puddle of water in the lower half of the opening. I'm using a turkey baster to suck out the fuel/water. The tip of the baster is right at the interface between the water and fuel.
The water was somewhat rusty, but I think the rust in the tank was minor, and once the water was out, the rust should stop. I keep the bike in the garage, and I use Chevron Techron fuel treatment every few tanks to remove any water.
All the water and fuel must be removed. I wiped the inside of the tank clean and dry as much as possible.
