I have been pumping out my tank through the pick up from the gas tank. It seems to be the best way to get all the water out of it. I am now at the what I feel is the bottom of the tank. What else can I put in to get the rest of the water out of it? I did open the top of the tank where the float is. That was an impossible task because the screws were under the floor of the boat which is a 1996 Aquasport Explorer 215. I seemed to have beeter luck with the pick up. I will be changing the the water seperator as well. I was told that I could put alcohol in the tank. Is that true?

Re: Gas Tank Question

Alcohol absorbs water. Dump is a gallon of denatured alcohol and let it sit a while. Then pump it out and dispose of it.

Re: Gas Tank Question

Gas also floats on water. If you get to good gas, you have pulled all the water out.

Re: Gas Tank Question

That last poster was nearly right. The water sits on the bottom of the tank. It is the last to come out, unless you can get the siphon hose flat on the bottom of the tank, and suck it out first.

Re: Gas Tank Question

I should have been more clear...sorry about that.

When siphoning gas through the pick up tube, make sure your tube is roughly 1/8" from the bottom of the tank. that is the norm in most tanks I've seen.

If you put good gas in the tank, allow 12+ hours for everything to settle and seperate. Slowly siphon off the water from the tank until you get to fresh gas. At that point, usually fuel stabilizer will be sufficient to allow the warer to be burned with the remaining gas.

I would recommend adding a clear water/gas seperating filter inline. This way, you can see the gas going through and the water will collect at the bottom of the unit, allowing you to drain it off.

Hope that was more clear! :)
