Anyone know if you get water in your tank(condensation-ice) were does it go, to the top of the gas tank the bottom or does it all mix together in there. thanks Crash dummy

If the sled is moving, running, etc, the water and fuel mix together a little and kind of turn a milky / cloudy color. Once the sled sits a while, the water and ice will separate and the fuel will float on top of the water.

It is often very difficult to separate them, sometimes a complete drain and refill is in order.

Thanks 'versatileman'. I keep my sled in the garage, and from warm to cold temps the garage gets a lot of moisture. when I take the gas cap off to fill, sometimes there's ice on the bottom lip of the fill hole. and im thinking im getting water in the tank some how, I gues i need :heet or stp??

Water tends to puddle and it and ice eventually end up in whatever low spots they can reach. It may be the bottom of the tank, a fuel line or filter, or carb bottom. Water which accumulates and freezes will eventually lead to fuel starvation. Isopropyl is one good way to remove it as it allows water, small quantities of it anyway, to move through the system without becoming ice. You can also use a drop-in-tank fuel absorber.

Water in fuel is an enemy and needs to be kept out. The best way is to avoid fuel from containers which might collect and contain water already. (I know this is almost impossible in some places.) Moisture collection in tanks can be largely prevented by keeping the machine's tank full, especially when the machine is stored in cold temps. Liquid cooled machines which have heat exchangers under the tank will warm the fuel and sometimes allow the ice to melt to water. This can created problems when the machine is shut off and the water freezes where it is - often in the lines. The liquid water which allowed fuel to pass when things were warm can completely block passage after is freezes and make restarting the machine a very problematic puzzle. Sometimes even refueling with cold fuel will freeze that water. The best way I have found to prevent icing in the fuel is to add isopropyl gasoline deicer every time I refuel. All it takes is a few ounces, perhaps three or four. Done regularly and by making your best effort to keep the fuel clean, you wil araely have ice problems.

if you have water in there,,, just drain the fuel and run it in your car or truck,,, running water through your sled motor will result in a rebuild,,, that can start to get pricey,,,,
I am not sure this would even work but, would a water seperator work like on I think some diesel engines have plus airlines? I'm not even sure if this would be feasible but hey?, just a little thought I had.
What do you think?
