How to eliminate water from gas?

I'm getting tired of dumping old gas out of the tank. Has anyone had and successfully resolved this problem? If yo, how? Thanks! Barney

I personally use "Sea Foam" in my gas tank which you can buy at any automotive store. I think another one is "Sta-bil". Ethanol does attract water/condensation in the gas tank so adding either of those will help the boat and also auto engine too. Good luck to you. Marty Durham Johns Island,SC 1991 BW 15' Sport GLS

Just do a search and you'll be able to read more than you ever wanted about it's effects. Bottom line, fuel additives have become necessary against the evil ethanol.

If you solve it please tel me how.

I know a lot of guys do not like separators with on deck tanks but I know they keep a lot of water out of the motor. I have had to spin mine off and dump it to get the boat running. From that I learned to dump it often at home and keep a spare in the boat. The problem is you will have the same amount in your tank. I would not dump the entire tank. as water settles I would drop a tube and siphon the bottom until you get good gas. I know this can be done I used to have to do it to my 20 outrage. I would just pump the primer bulb in the yard until I got good gas then reattach it to the motor. After that the separator will help keep the smaller drops out of the motor.

I am glad that I have a relatively large tank for my boat. Chevron stations aren't too plentiful but I know where one is now on my route to a fishing hole. Alphonse 2009 Montauk 170

I assume that is a 3 part assembly and the bowl attaches to the bottom of the filter. Is that correct? After searching around, it looks like the replacement filters cost about $20.

For those with portable tanks: - inspect any O rings/gaskets. If worn or old and dried out, replace them. - Remember to close the vent when the boat is not in use.

Ethanol is not nearly as big a problem in cars because we use the fuel so fast. The best thing you can do for yourself is run the engine a minimum of 30 minutes a week, and make sure you're doing a complete gas turnover in your tanks every 45 days. Also, be careful to use a fuel water sep that is factory recommended for your engine. Many of them will restrict your fuel flow to an extent of causing flow problems higher throttle demands. Right now there is only 1 sep that Mercury approves and it's restrictive measure is less than 2.5 inches of mercury(the stuff in the thermometer, not the engine manufacturer). Anything higher than that is known to cause other problems. Duane G Winter 1984 BW Sport 15 Center Console

By keeping the tank full, you reduce the amount of space for condensation. Condensation, over time, can lead to phase separation and this what needs to be avoided. 1992 Outrage 17 I 2019 E-TEC 90, Viper 17 2+ 2018 Load Rite Elite 18280096VT

That along with searching the net sure makes life easier than the old days. The fittings from my old filter aren't the same thread as the new one. I guess I should have thought of that when I was at the store. As rusted together as my old unit was, I don't want to use any of the old parts anyway. Edited by arthureld on 04/24/10 - 12:03 PM
