DIY Gascolator

Hmmm, I guess a gascolator is a fancy name for a sediment bowl. My 1955 John
Deere had a sediment bowl. If I had called it a gascolator I would have been
laughed out of the county.

So a gascolator is simply a water separator, OK?
--------------------------------------------------------------------------------------------------------------

More or less, yes.

--------------------------------------------------------------------------------------------------------------
I thought it a lot more complicated -
an easy way to get lost in explanations.
--------------------------------------------------------------------------------------------------------------

It IS a lot more complicated. The body of the Gascolator provides a
place to attach various fuel lines. On a simple airplane -- one
lacking even a fuel pump -- the Gascolator offers more convenience
than other methods..

-------------------------------------------------------------------------------------------------------------
-) why does one want a water separator apart from the fuel filter?
-------------------------------------------------------------------------------------------------------------

I give up. Why?
In fact, most Gascolators DO provide for fuel filtering as well as
water separation.

-------------------------------------------------------------------------------------------------------------

In my house's heating, there's a filter cartridge in a glass bowl,
and when I ran the tank dry it sure filled up with water (and smudge).
Isn't it sufficient to mount the fuel filter at the lowest point,
and have a water drain valve on its bottom?
------------------------------------------------------------------------------------------------------------

Yes, a water drain at the lowest point should prevent water from
reaching the burner. But I am not familiar with the oil burners used
by many Americans. Based on your description I suspect there is an
auxiliary circuit open to the atmosphere that is only allowed to drain
when the main tank is completely empty, but that is only a guess.

-----------------------------------------------------------------------------------------------------------

-) is there a finer fuel filter in the Ford A & T, or only the
strainer in the tank?

--------------------------------------------------------------------------------------------------

No; not as a stock item. As I recall, the strainer fits down inside
the filler neck and there were a number of after-market filters that
offered a finer mesh than the stock filter.
-------------------------------------------------------------------------------------------------

Do you recommend a finer filter, either
between tank and gascolator or between gascolator and carb?

------------------------------------------------------------------------------------------------

That's two questions :-)

The Gascolator has a finer filter than the one in the filler neck.
You should not need any additional filtering.

---------------------------------------------------------------------------------------------
-) why the "sintered bronze muffler" on the exit?
---------------------------------------------------------------------------------------------

Because the 'exit' of the Gascolator is the inlet to the carburetor.

--------------------------------------------------------------------------------------------
actually, what is a "sintered bronze muffler"?
--------------------------------------------------------------------------------------------

A muffler -- the types vary -- is standard equipment for pneumatically-
powered tools, which have an extremely high noise signature. Sintered
bronze mufflers do not corrode nor 'pack-up' like some other types of
mufflers.

---------------------------------------------------------------------------------------------
Does it serve as a filter, perhaps?
---------------------------------------------------------------------------------------------

See the above.

--------------------------------------------------------------------------------------------
-) for the receiver body, I should like clear plastic:
less delicate than glass, but unlike metal, it shows what's happening.
There must surely be clear plastics that resist gasoline?
-------------------------------------------------------------------------------------------

I'm sure there is but the goal here is to describe a Gascolator that
can be fabricated by the typical homebuilder. As for showing what's
happening, it would ALWAYS show full; there would be nothing to see.
As for plastic vs glass or metal, my personal preference -- and that
of many other homebuilders -- is to keep keep the amount of flammable
materials forward of the firewall to an absolute minimum.
