Fuel/Water separator's By larrball (Read 855 times)

Has any one given these a try? And if so what was your findings.

Now it's been years ago but i remember seeing something like this that a outside sales person at a repair shop i worked was showing us, but because back then E10-E85 was not even being used, i didn't take notes because water in fuel was not a big concern back then, as it is now if your filling up with E-10 fuel that attracts water and condensation then the good ol unleaded fuel of yester years.

And this one that looks just like the fuel filter that a lot of us seem to always recommend (prime line #7-02357-1) but if you look close it has what looks like a tube thru the center that acts as a water separator?

As you can see the only real difference looks to be the silver tube.

Any one remember the glass bowls like on an 8N ford tractor? They work great. I still use an 8N around my place. With the gas I been buying I have not seen any water in the bowl and the tractor is kept in the barn so I don't have to deal with weather getting in it.

Gas floats on water, that's how a separator works. It needs fairly calm conditions for gravity to do it's work and let the water sink. That's why the glass bowl filters John mentioned work so well. I really don't see how a funnel would provide those conditions while you're trying to pour gas through it into a tank. If it did work you'd be waiting an hour for the gas to get through. A gallon of E-10 will absorb about four tablespoons of gas before the excess starts to separate out (phase separation) and sink to the bottom. This typically takes about 3 months or more of exposure to humid air. So if your gas isn't older than that the water in it isn't going to come out using any gravity method. I think the funnel would be a waste of time and money, the little filter would have to have a catch reservoir and I don't see one. JMO, Rich
