J-Moe, from afar and going on what you have described, it does not sound like you have any problem.

First, in the order you asked: Gasoline mixed with blue two stroke oil tends to look greenish in a clear glass separator bowl, especially if your fuel is not clear but yellowish. (remember blue & yellow colors mix to green) Do you mix your oil in the tank, or does your Tohatsu have a separate reservoir?

Second, it does no harm to dump the bowl of anything, including gasoline.

Third, there should always be liquid fuel in the separator bowl, and it may fill completely with fuel with no air pocket, or may have a small air pocket. The bowl is designed to provide a place for water droplets to settle out of the fuel. If you have any water, it will show itself as clear droplets sitting in the bottom of the separator bowl. Only if you are pumping gross amounts of water in your fuel would the bowl ever fill with water. Running portable tanks as you do, unless you get a load of bad gas, it is unlikely you will ever see water in your separator.

All that said, if you do as Whalerman has suggested, you will probably feel better and you can assure yourself there is no issue (or you could find you have a load of bad gas). At any rate, the cost of doing this is about 6 gallons of fuel??

Let us know what your outcome is please!
