I have a little water in mine right now from wet sanding. I let it settle to the bottom and pump it off. If you pump some off the bottom into a can you can see the separation line and pump it back into the tank, jus stop above the water line....then add the water stuff.

Yes, the water settles to the bottom, I can see the line in my tanks. You'll be able to see a line in your can as well. I dont know what to use yet.

sweet, yea i had one of those on my jetboat. my tanks are so small now fuel dont sit around long....usualy. I used to maintain a fleet of vehicles including all the bosses toys. One time they all went to Dumont or Glamios or some shit and their feul barrel got rained into so everything quit ruinning, killed the weekend for them. When they got back I took a short peice of hose and went around and siphend a little off the bottom of the tanks/ drained float bowls and away we went.

ya, poor a bottle of rubbing alchool in each tank... that well help seperate the water from the gas and help it evaporate...
