I was concerned about water in my gas, as we had had some issues on our San Juan cruise last summer. So I wanted to see what we had. There have been threads on this before, this is to explain my fairly cheap and reasonably efficient system.
It is built around the Mr. Gasket Micro Electrical Fuel Pump #12S, about $30 at a number of places on the net. I thought about a lot of fancy ways to put this all together, but in the end opted for the simplest possible way, just mounting the pump on a piece of board.
The rest of it is (a) connect up 12 volt power, (b) put an outlet hose on it, and (c) connect a hose from the fuel-water separator to the pump inlet. Here is what the whole thing looks like before connecting the inlet.
I was going to make a separate hose with a Honda connector to run to the connection on the fuel-water separator for the inlet, but looking at the existing fuel line to the kicker, I decided to just remove the clamp and use that fuel line as my inlet line to the pump.
I had read up a lot on the Mr. Gasket fuel pump, and the key according to everyone is to mount it at or below the level of the gas tank, which tells me that it does not have a lot of lift. So I placed it on the starbord trim tab.
Finally, I ran the outlet hose to a 4 liter glass jug so I could see what I was getting. The first 8 oz or so was thick, so I discarded that, but then I was getting nothing but good looking clear gas. I poured the gas into a legal 5 gal gas can, and then used that to fill my F250 and the Titan, since the gas was purchased in September, and I want to go to the Grange in Issaquah and fill the boat with fresh non-ethanol gas.

For power, I used "Big Green," our heavy duty jump starter. It took about 2 minutes 20 seconds to fill the 4 liter jug, so without doing the math, I am assuming that is about half a gallon a minute.
You could add a second fuel-water separator to the outlet of the fuel pump if you were seeing water in the gas being removed.
Obviously this system can't be used while the boat is in the water, but it works like aces while the boat is on the trailer!
