Water in the tank

A well-known had just brought me his scooter with statement he just jumped out for a short time and then no more. He was put off in the fall and there was everything in order, he wanted to get a sign tomorrow and now he no longer goes, big owl. Since I am not yet switched on summer time I thought about what he is doing. Ignition on and tank almost empty, candle out and moist, so came the idea. Underpressure and petrol hose off, one glass taken and the suction emann played,result see picture. That comes from when he is not fully fueled when for winter he is sent in sleep and not reasonably covered if no real parking space available. Half hour work and he may get his sign tomorrow. Addendum: those who can’t do anything with the picture,the bottom is water and above gasoline.
