Hi gang,

  

 Considering installing a Racor Fuel Filter/Water Separator in place of regular fuel filter.

  

 Normal Mister Funnel and preflight fuel samples should take care of fuel source and condensation problems, but with ethanol fuels in our future would this be enough?

  

 Water and alcohol mix quite readily. Would a water filter tend to separate the alcohol along with the water from the rest of the fuel? Could a water/alcohol emulsified mixture get by normal fuel checks?

  

 Not worth worrying about?

  

 Would like to hear general comments and as well as from those who may be using this type of filter.

It's not very light but it has worked so far.

water/alcohol emulsified mixture get by normal fuel checks?

If we get a small percent of alcohol in our gas....  then we will have no
	


concern for water in the gas.....    unless we get more water than alcohol

in our systems....  a water alcohol mix of 50 - 50   will mix and burn

without problems  in our fuel....  the water wont separate out until the

water is greater than 50 % compared to the alcohol in the fuel.   to check

for alcohol in the gas is quite easy...    fill a test tube 1/2 full with

water, then draw a line,,,  then fill it the rest of the way with gas,

shake it up and let it settle.   The difference between the line and the

water / gas line is the amount of alcohol.      Now to test for the purity

of the alcohol will take a bit more time but is done in near the same

way....   fill the test tube to the first line with gas....    slowly put in

drops of water and shake between drops.  When you first start noticing water

in the bottom of the test tube,  you will know how much water the alcohol in

the gas will absorb before it starts to settle out.

For example...   if you have a test tube marked from 0 to 150 CC...  fill it

to 100 with gas...   if it is 5 percent alcohol in the gas...   you should

be able to fill it to the 105  before the water starts to settle in the

bottom....   if you only get it to 102....  then the alcohol in the gas

already had water mixed into it,, or it was only 2 percent alcohol in the

gas to start with.



Any way until you get enough water into the gas to cause it to settle out,,,

it will burn ok.

Doubt if any filter that we could afford/lift would separate the fully miscible mixture of alcohol and water into its parts. Distillation?

Boyd,

  

 Was thinking, by using the water separator to filter the water/alcohol mixture, maybe it would remove the alcohol as well.

  

 Thanks for the info on testing the fuel. Sounds easy to do in the field when your not sure of the source.

Haven't used it on the plane, but I've used a Racor fuel/water separator on my outboard boat for several years, and it does a dandy job.                  Lar.
