Primer should pump approximately 10 cc of alco-
hol
in
ten strokes. If pump fails to pump alcohol,
disassemble
and check for missing, cut, or split
0-
rings or damaged check valves.
IMPORTANT: After installing, check for leaks by
connecting
fuel tank hose to outboard and
squeezing primer
bulb until definite pressure
is
felt
in
the bulb.

WARNING
~
After servicing the fuel system, check for
leaks. Failure
to
check for fuel leakage
could
allow a leak to go undetected,
resulting
in
fire or explosion.
Before replacing a suspect fuel pump, remove
and
clean the fuel filter and install a new filter ele-
ment. Also, remove the fuel hose from the fuel
tank and blow through
all
passages and hoses
with
low-pressure compressed air to
be
sure they
are open. This might
be
the cause
of
inadequate
fuel delivery. If this procedure does not correct the
trouble, perform
Fuel
Pump Pressure Test on
p.145
.
IMPORTANT:
To
prevent excessive fuel spill-
age, disconnect hose connector at outboard
before
disassembly.
Disassembly
Loosen cover screw and remove cover. Do not 6
lose small O-ring from around center post or large
O-ring
from outer edge of cover.
