LATE MODEL FUEL TANK SERVICE
1-
Late
model
fuel
tanks
(since
about
1959), are not pressurized.
A squeeze
bulb
is used to move fuel from
the
tank
to the
carburetor
until
the
engine
is operating.
Once
the
engine
starts,
the
fuel
pump,
mounted
on the engine,
transfers
fuel from
the tank to the carburetor.
2-
The pickup unit in the tank is sold as
a complete
unit, but without
the gauge and
floa
t.
3-
To replace
the pickup unit, first
re-
move the
four screws
securing
the
unit
in
the tank.
Next,
lift the pickup unit up out
of the tank.
4-
Remove
the
two
Phillips
screws
se-
cur ing the fuel gauge
to the bottom
of the
pickup
unit
and
set
the
gauge
aside
for
installation
onto the new pickup unit.
If the pickup unit is not to be replaced,
clean and check the screen
for damage.
It
is possible
to bend a new piece
of screen
material
around the pickup and solder it in
place
without
purchasing
a complete
new
unit.
Attach
the fuel gauge to the new pickup
unit
and secure
it in place
with
the
two
Phillips screws.

5-
Clean
the old gasket
material
from
fuel
tank
and old pickup
unit
(if the
old
pickup
unit
is to
be installed
for
further
service).
Work the float
arm down through
the fuel tank opening, and at the same time
the
fuel pickup tube into the tank.
It will
probably
be necessary
to exert a little
force
on the float arm in order to feed it all into
the hole.
The fuel pickup arm should spring
into place once it is through
the hole.
Se-
cure the pickup and float
unit in place with
the four attaching
screws.
6- The primer
squeeze
bulb can be re-
placed
in a short
time.
A squeeze
bulb
assembly,
complete
with the
check
valves
installed,
may
be obtained
from
the
local
OMC dealer.
