4-68 FUEL
An arrow is clearly visible on the
squeeze bulb to indicate the direction of
fuel flow. The sqeeze bulb
MUST
be instal-
led correctly in the line because the check
valves in each end of the bulb will allow fuel
to flow in ONLY one direction. Therefore
if the squeeze bulb should be installed back-
wards (in a moment of haste to get the job
done),
fuel will not reach the carburetor.
7- To replace the bulb, first unsnap the
clamps on the hose at each end of the bulb.
Next, pull the hose out of the check valves
at each end of the bulb.
New clamps are
included with a new squeeze bulb. If the
fuel line has been exposed to considerable
sunlight, it may have become hardened
causing difficulty in working it over the
check valve. To remedy this situation
simply immerse the ends of the hose i~
boiling water for a few minutes to soften
the rubber and the hose will then slip onto
the check valve without further problems.
After the lines on both sides have been
installed, snap the camps in place to secure
the line. Check a second time to be sure
the arrow is pointing in the fuel flow direc-
tion,
TOWARDS the engine.
8- Use two ice picks or similar tool, and
push down the center plunger of the connec-
tor and work the O-ring out of the hole.
9- Apply just a drop of oil into the hole
o~ the connector. Apply a thin coating of
011
to the surface of the O-ring. Pinch the
O-ring together and work it into the hole
while simultaneously using a punch to de-
press the plunger inside the connector.
