Fuel/Water seperator?

[Nasty]

Does a motor need a fuel/water seperator if ethanol is never used in the gas tank? Or, just the ability to filter the gas worth it?

I would use one just to be safe. You will still get moisture in your tank with pure gas.

I have put them in every boat I have owned. It's a small price to pay for the added insurance you get by keeping your fuel system clean.

I aint no expert and I aint no chemist, but as I understand it is seperators don't work on ethanol gas anyways. On acounta the ethanol bonds to the oxygen on the molecular level so it aint like water in ya tank, the water is actually attached to the ethanol. ya can have water in ya ethanol gas with no water loose in ya tank and it will gum ya up separator or not. So to me the best answer is use a separator and stay away from ethinol gas. A shot of staybil or sea foam don't hurt either. Working away from home for anywhere from 2 weeks to 3 months at a time, ethanol worries every motor I got. use the separator for ya non ethanol gas cause it takes out suspended water from condensation and such. But ya still gotta avoid ethanol cause the filter don't help that problem.

Your right, water attaches tot he ethanol and will pass through your filter. Using a filter will trap any particulates which is trash in your gas and will plug carbs or injectors.

Yep, even if it doesn't help with moisture (which I'm not sure about) it sure helps with trash.
