fuel. The diaphragm can start and
stop
many
times
in
each mile of vehicle operation, but the pump
actuating lihkage is always in operation while the
engine
is running. The fuel pump incorporates a
pulsator and pulsator chamber to dampen the
effect
of pump pressure pulsations on the carburetor
needle
valve.
This
prevents high fuel level in the
reservoir
that would result from the
needle
being
jarred
away from its seat. Also, operating
economy
would be affected because a high fuel level usually results in an over-rich mixture.
The
actuating linkage has its own spring to ensure
continuous contact of the lever to the camshaft
eccentric.
This
fuel pump has a sediment bowl and filtering
screen which is attached to the top of the pump by
a
wire clamp and thumb nut. The screen and sedi
ment bowl should be cleaned at least twice yearly
to prevent trouble due to a blocked screen or water
freezing. The bowl should be washed and wiped
dry
and the screen dried and then cleaned with a
stiff
brush.
When reassembling the bowl make cer
tain
that the cork gasket is not broken; reverse it
and
position it flat on the seat, then install the
bowl and tighten the thumb nut securely. After
cleaning, start the
engine
and carefully inspect the
bowl for leakage.
E-46.
Disassembly
Remove the cover plate, gasket, and screen or
bowl clamp, sediment bowl, gasket and screen if so equipped.
Mark
the two castings with a file to
ensure positioning in the same relation upon
assembly. Remove the screws attaching the fuel cover to the pump body. Remove the cover,
diaphragm,
and spring. Remove rocker arm pin,
rocker
arm, and rocker arm spring. Remove the
valve plate screw and separate the valve plate
retainer,
valve gaskets, and valves.
Clean
all parts in cleaning solvent and blow out
with
compressed air. Valves should not be removed
from
the valve housing assembly.
Check
all parts
to see that
they
have not
been
cracked or broken
and
that screw threads have not
been
stripped or
cross threaded. Refer to Par. E-49 for fuel pump
testing. 126

HURRICANE
F4
ENGINE
•
Late
Models.
The
Hurricane F4
engine
is equipped with a single-
action fuel pump (Fig.
E-31).
The fuel pump cam lever is activated by an eccentric on the
engine
camshaft. When the carburetor float
needle
valve
closes, accumulation of fuel in the pump
extends
the diaphragm spring.
This
action causes the rocker
arm
linkage to
become
inoperative until the pres
sure on the diaphragm and spring is reduced. The fuel pump discharge pressure is thus controlled by
the diaphragm spring.
This
provides a steady sup ply of fuel to the carburetor at a fairly constant
pressure.

•
Refer to Fig. E-32.
a.
Assemble the valve housing and filter cover, using a new air
dome
diaphragm. The opening
in
the air
dome
diaphragm is located over the
intake
valve. The filter cover is positioned cor
rectly
when the inlet passage in the cover aligns
with
the inlet valve. Tighten the attaching screws
alternately and securely.
b.
Lubricate
diaphragm assembly shaft, around
oil
seal, with
engine
oil. Position diaphragm as sembly on valve housing and thread all the attach ing screws through diaphragm.
(This
helps avoid
damage to the screw
holes
in diaphragm.)
c.
Place diaphragm assembly and valve housing
in
position on pump body (align marks made
before disassembly).
First
start all screws one
or
two threads; then tighten the screws alternately
and
securely.
d.
Lubricate
forked end of cam lever, pin bore
of body, and corresponding
hole
in lever, and the
pin
itself with
engine
oil.
Note:
Forked
end of lever
goes
around diaphragm
shaft. Be sure
loose
bumper washer on diaphragm shaft is on top of lever and
between
lever and fixed
washer
on shaft.
e.
Install
lever and pin. To install pin, use a drift
and
tap pin into the
hole
in the body until it hits
the
stop
on the
bottom
of the hole;
move
the lever while tapping, to align
hole
in lever with the pin;
then install plug.
Install

f.
Install
a new filter bowl gasket in filter cover.
Place
bail
assembly in ears on cover and swing
to one side.
Install
spring and new filter element in
bowl and install bowl on pump. Position
bail
as

Caution:
Do not overtighten screw.

Fuel
Pump Testing
Whenever
the fuel pump is to be checked for pres
sure
or volume, follow the procedure outline in
Par.
C-23 of this manual.
Fuel
pump pressure is
important
for low pressure
will
seriously affect en
gine
operation and high pressure can cause exces
sive fuel consumption and flooding of the carbure
tor.
Should there be any doubt of normal opera
tion, check the procedure as outlined in Par. C-23.
In
addition to proper fuel pressure, volume of the
pump is also important. When testing for proper
pump pressure, be certain to also
test
for volume
as the pump may build up sufficient pressure, but
fail
to produce sufficient volume.
