Water in Fuel Tank

[thedink9]

I believe that I have a substantial amount of water in my fuel tank. Problem is that there is almost a full tank of fuel ( almost 100 gallons). I am thinking of seting up a closed loop system consisting of a good quality water separating filter along with an electric fuel pump. I want to take off the fuel sending unit, stick a 3/8 inch hose into the lower corner of the tank and attempt to drain / recycle the fuel through the filter and back into the tank.

If I locate the hose low enough in the tank, does anyone see a reason why I couldn't be reasonably successful?
Does anyine have a better idea?
