the work area. In addition, do not permit any
smoking, open fire, or work of a nature that
could produce sparks in the area.
5. Connect fuel line to fuel tank outlet.
6. Tighten fuel line clamps and front to rear
fuel line connection.
a. Removal of Rear Section
1. Raise rear end of car.
2. Remove right rear wheel.
3. Disconnect fuel outlet line at fuel tank.
4. Remove five clips that secure fuel line to
inside of right rocker panel. If car is equipped
with Air Conditioner, a dual clip is used to hold
fuel and vapor return lines.
5. Remove two clips, one ahead of and one be-
hind connections between front and rear sections
of fuel line.
6. Disconnect the two sections of fuel line and
remove rear section by rotating it until it works
free of axle housing.
b. Removal of Front Section
.1. If rear section has not been removed, dis-
connect front and rear sections at connection
and plug rear line to prevent loss of fuel. Remove
clip holding front section to frame side member.
2. Disconnect front fuel
and remove front section.
line at flexible hose
c. Installation of Front Section
1. Position front section of fuel line and con-
nect it to flexible hose.
2. Secure line to frame with clip at rear end
of front section.
3. If rear section of fuel line was not removed,
unplug line and connect front section to rear
section.
d. Installation of Rear Section
1. Position rear section of fuel line over axle
housing.
2. Connect rear section of fuel line to front
section. Do not tighten connection.
3. Install five clips along inside of rocker
panel. If car is equipped with Air Conditioner,
larger diameter fuel line should be installed
inside and vapor return line on outside.
4. Install clips on both sides of front and rear
-fuel line connection.
14. Fuel Pump T>sts
1. To check fuel pump capacity, disconnect
fuel line at fuel filter inlet and fuel pump outlet.
Being careful not to bend tubing, reposition tubing
on fuel pump outlet so that fuel may be dis-
charged into a container and secure line to fuel
pump.
2. Raise front end of car.
3. Disconnect flexible line at steel fuel supply
line on inlet side of pump near front motor
mount. Plug steel fuel supply line to keep gasoline
from draining out of tank.
4. Insert disconnected end of flexible line into
a quart container of kerosene or solvent. Be
sure end of hose does not rest against bottom
of container and container is at same level as
fuel pump.
5. Crank engine until approximately 1/2 pint
has been pumped and then check output. Pump
should displace a minimum of 280 cc of kerosene
per 10 strokes (fuel spurts) at cranking speed.
Seventeen strokes should fill a pint container.
If liquid is delivered as specified, pump delivery
is normal. If pump delivery is below normal,
check for the following:
a. Diaphragm flange or pulsator cover screws
loose. Tighten screws.
b. Loose connection on inlet side of pump.
Tighten fitting and use new hose clamp.
c. Flexible inlet line pinched, broken, porous,
or obstructed. Replace flexible line.
d. Check camshaft eccentric for wear visually
by using mirror and flashlight through mounting
flange.
6. If pump does not operate properly after
these corrections have been made, overhaul or
replace pump.
NQTE: By following the procedure given
below, the displacement capacity of the pump can
be increased by as much as 5 cc per stroke.
7. When installing pump, crank engine until
cam eccentric is at lowest point. With mounting
screws loose, lift up on pump. At the same time,
tighten screws to 15 foot-pounds.
8. To check for pump pressure, remove fuel
line at pump outlet and install pressure gage.
