I can easily Siphon at least 95% of the old gasoline for a tank that has been abused for over 10 years with 1/4 tank of gasoline left in it. (the fuel pump failed, and the previous owner was too cheap to fix).
The question is: what treatment do I add to clean the gunk out of the gasoline tank (not rust, thankfully) What specifically makes that treatment the best?
