Polishing gas

Just for giggles, I signed up for the Rosborough list. Here is an interesting post on dewaterizing your gas:

The easiest way to deal with the water without disposal issues and without losing $200 worth of gas is to build you own fuel polisher. Mount an electric fuel pump and water separating filter on a piece of Starboard, AZEK or plywood.. Hook your fuel line up to the input of the pump and have the output run thru the filter and then back into your tank or vent. You can wire the pump with big alligator clips like boosting cables for a quick connect to your batteries. (be alert to gas fumes in enclosed spaces). Lots of big boats have these permanently installed for dealing with contaminated fuel in remote areas. You can cycle all your fuel as often as you like without running your engines.If your fuel is half water you can pump it into a 5 gallon pail and in a few minutes the water will sink to the bottom then you can use the pump input to suck the gas off the top and put it back in the tank. Then you can polish the fuel as outlined above as the water will be down to a manageable level. Sounds harder than it is.

If you have that much water in your gas tank when you need to better label the fuel and water caps. :lol:

I wish I had this setup or Bob Thataway's setup to pump out fuel. We just salvaged an old boat and removed 60 -80 gals of 10+ yrs old gas with a gravity powered siphon line. It took hours to remove the fuel.
 
This is similar to what I did with the C D 25--but I take some exception with the aligator clips. I use ring terminals to connect the pump to the battery--and there is a ignition proof switch (spark protected) between the posative and pump.

The danger is that you have gas fumes, and the alligator clips which can arc or produce a spark when you connect or disconnect. This could cause an explosion or fine. Hook up the battery--which needs to be a little way from the gas anyway--and then turn the pump on and off with the protected switch.

The bucket is a good idea--only time I had that much water in a tank it was diesel, half way across the Atlantic--I'll confess, I pumped that water overboard--along with some diesel fuel--I did the wrong thing--but no other way to dispose of the water/diesel combo--after the 10 or so gallons of salt water was gone, then it was just regular polishing. The water was sucked in thru a vent because the vent was under water (boat was heeled at over 45 degrees much of the time).

Bob - when it comes to surviving or not, there is no such thing as the wrong thing. You do what ever is necessary to make it.

"dewaterizing my gas"

I'd use the Hopkins Shaker Siphon to Racor Fuel Filter Funnel into a 5 gallon jerry jug. Fills a 5 gallon jug in about 2 minutes

No problems so far.
