FUEL
STORAGE
The importance of proper storage of fuel cannol
be
too strongly stressed. Storage tanks, drums, or
service tanks must
be
free from rust, scale, sedi-
ment, or
any
other foreign molter which
will
contaminate the fuel. Dirty fuel
will
clog the fuel
filters
and
eventuolly
damage
the fuel pump
and
injectors.
A portable storage tank provides the best method
for storing fuel on the job.
In
a storage tank, the
sediment
and
water can easily
be
drained
and
the
fuel can be pumped into the tractor fuel tank with
a
minimum
of handling. Consult your nearest"Allis-
Chalmers" Dealer for details
about
this type
of
storage tank. Since condensation
will
occur
in
the
storage tank,
it
is
very important
that
a sediment
sump be provided
50
that
water
and
se'ltlings
ccm
be drained daily.
Fuel
should be allowed to settle
at
least
48
hours
in
the storage container before
it
is
added
to the
fuel tank of the tractor.
It
is
advisable to use a
pump
and
draw the fuel from the container rather
than to drain
it
from the bollom of the container.
Where conditions
are
such that drums must
be
used
to supply fuel,
it
is
advisable
to
have enough drums
to allow sufficient time for the fuel to sellie. The
fuel should be used only to within about three
(3)
inches from the bottom of the drums.
The
fuel thus
left
in
a number of drums can be collected into
one drum
and
used after the usual time allowed
for settling.
In
this
manner, the sediment
and
for-
eign matter
will
be disposed of
and
no fuel
will
be
wasted. Whenever drums
are
used for fuel
storage,
they should
be
covered
or
placed under shelter
to
avoid contamination of
the
fuel
by
water, which
will
enter through the filler plugs when it rains,
even though the plugs
are
tight.
The fuel tank of the tractor should
be
filled
at
the
end
of
the day's run rather than
at
the start; this
will
reduce the water content,
as
a
full
lank
is
less
subject to condensation. The tractor fuel tank
is
provided with a drain elbow
and
drain cock, for
draining accumulated
waler
and
sediment.
