Decided to transfer the remaining fuel in my Mako 17 fuel tank (not pre-mixed) to my truck to burn before it goes bad. So I siphoned it through the bulkhead mounted cannister fuel filter/water separator. <br /><br />I figured I'd change out the filter, too and did so. Took the old filter and inverted it over a glass container and emptied about 1 cup of rusty water out. I presume there's probably more in the bottom of the tank below where the pickup tube can reach. Any recommendations of something I might add to soak up any water that might be there? We used to use acetone, but I don't think that's a good idea with all the plastic in the carbs these days. Engine's a 1990 Evinrude 120.
