HOW IT WORKS

BY JILL W. TALLMAN

Water guard

The gascolator traps what shouldn't go through the engine

STEVE KARP

THE GASCOLATOR IS a catch-all of sorts, a small sump
that is designed to catch and trap water from fuel tanks
before it can travel into the carburetor of your airplane's engine..
From your very first preflight you most likely learned
that water in the fuel system is very undesirable, which
is why you sump small samples from the tanks through
fuel drains located under the wings and on the engine
side of the firewall. You then look for the presence of
dirt or water-which is heavier than aviation fuel-in
your fuel tester.
On many airplanes, that drain on the engine side of
the firewall is connected to the gascolator, which is
located at the lowest point of the fuel system. (Again,
because water is heavier than aviation fuel, so if its
present the water will collect there.)
The bowl in the gascolator includes a fuel filter
screen, an in port and an out port. The bowl is generally made of metal, though much older aircraft had
gascolators whose bowls were made of glass-presumably so that the pilot could see any evidence of fuel
contamination.
During an airplane's annual inspection, the gascolator screen should be inspected and the bowl itself
should be checked to ensure no corrosion has begun
to occur.
THE GASCOLATOR is located at the airplane's
lowest point so as to trap water and debris before
it can enter the fuel system.
