GENERAL DESCRIPTION

The fuel pump
(fig. IP)
used
on all
Chevrolet vehicles

covered
in
this manual
are of the
diaphragm type.
The

pumps
are
actuated
by an
eccentric located on
the
engine

camshaft.
On
in-line engines,
the
eccentric actuates
the

rocker arm*
On V-8
engines,
a
push
rod
(located be-

tween
the
camshaft eccentric and fuel pump) actuates
the

pump rocker
arm.
Because
of
design, this pump
is

serviced
as an
assembly only.

Fig.
IP—Fuel Pump (Non-Serviceable)

SERVICE PROCEDURES

Inspection

The fuel pump should
be
checked
to
make sure
the

mounting bolts
and
inlet and outlet connections
are
tight.

Test

Always test pump while
it is
mounted on the engine
and
be sure there
is
gasoline
in
the tank.

The line from
the
tank
to the
pump
is the
suction side

of
the
system and the line from the pump
to the
carbure-

tor
is the
pressure side
of the
system.
A
leak on
the

pressure side, therefore, would
be
made apparent
by

CHEVROLET CHASSIS SERVICE MANUAL

ENGINE FUEL 6M-11

dripping fuel, but a leak on the suction would not be ap-

parent except for its effect of reducing volume of fuel on

the pressure side.

1.
Tighten any loose line connections and look for bends

or kinks in lines.

2.
Disconnect fuel pipe at carburetor. Disconnect dis-

tributor to coil primary wire so that engine can be

cranked without firing. Place suitable container at

end of pipe and crank engine a few revolutions. If

little or no gasoline flows from open end of pipe then

fuel pipe is clogged or pump is inoperative. Before

removing pump disconnect fuel pipe at gas tank and

outlet pipe and blow through them with an air hose

to make sure they are clear. Reconnect pipes and

retest while cranking engine.

CAUTION: Whenever the engine is cranked re-

motely at the starter, with a special jumper

cable or other means, the primary distributor

lead must be disconnected from the negative

post on the coil and the ignition switch must be

in the "ON" position. Failure to do this will

result in a damaged grounding circuit in the

ignition switch.

3.
If fuel flows from pump in good volume from pipe

at carburetor, check fuel delivery pressure to be

certain that pump is operating withint specified limits

as follows:

a. Attach a fuel pump pressure test gauge to dis-

connect end of pump to carburetor pipe.

b.
Run engine at approximately 450-1,000 rpm (on

gasoline in carburetor bowl) and note reading on

pressure gauge.

c. If pump is operating properly the pressure will

be within specifications and will remain constant

at speeds between 450-1,000 rpm. If pressure

is too low, too high, or varies materially at dif-

ferent speeds, the pump should be replaced.

Removal

1.
Disconnect fuel inlet and outlet pipes at fuel pump.
Fig.
2P-Installing 283, 327, 350 V8 Engine Fuel Pump

2.
Remove fuel pump mounting bolts and remove pump

and gasket.

3.
On V8 engines; if push rod is to be removed, remove

pipe plug then remove push rod (396 and 427 cu. in.

engines), remove fuel pump adapter and gasket then

remove push rod (283 and 327 cu. in. engines).

4.
If a new fuel pump is to be installed, transfer

fittings.

Installation

1.
On V8 engines; if removed, install fuel pump push

rod and pipe fitting or fuel pump adapter. Use.

gasket sealer on gasket or pipe fitting.

2.
Install fuel pump using a new gasket and tighten

securely. Use sealer on fuel pump mounting bolt

threads.

NOTE:
On V8 engines, a pair of mechanical

fingers may be used to hold fuel pump push rod

up while installing fuel pump (fig. 2P).

3.
Connect fuel pipes to pump.

4.
Start engine and check for leaks.

CHEVROLET CHASSIS SERVICE MANUAL

FUEL TANK AND EXHAUST SYSTEMS 8-3

CAUTION: Always drain gasoline from com-

plete fuel system including carburetor, fuel

pump and all fuel lines and fuel tank if the vehi-

cle is to be stored for any appreciable length of

time. This precaution will prevent accumulation

of gum formation and resultant poor engine

performance.

Removal and Installation (Except Station Wagon)

1.
Drain fuel tank.

2.
Raise vehicle.

3.
Disconnect fuel pickup line, ground wire.

4.
Disconnect meter wire at rear harness connector.

5. Disconnect vent pipe hose.

6. Remove tank support straps and lower tank carefully.

7. To install, reverse the removal procedure.
Removal and Installation (Station Wagon)

1.

vehicle. The fuel lines should be occasionally inspected

for leaks, kinks or dents. If evidence of dirt is found in

the carburetor or fuel pumto and disassembly, the lines

should be disconnected
and
blown out. Check the fuel tank

strainer for damage or omission. Note position of fuel

line clips for convertible models.
FUEL TANK VENT LINE

Sedan modei fuel tanks are vented to the atmosphere

at the top right- forward edge of. the tank. The vent line

is connected by a rubber hose with two clamps one at the

tank and the other at the vent pipe which is secured to

the underbody A rubber grommet around the vent pipe

acts as a seal to prevent gasoline fumes from entering

the.passenger compartment.

IMPORTANT: It is important to note that the

sedan gas tank cap is non-vented. It is neces-

sary to be assured that the vent line is free from

dirt, etc., and open at all times. If gasoline

fumes are detected, the rubber grommet should

be checked.

Station wagon models use a vented, anti-surge type gas

tank.

GENERAL DESCRIPTION

All models
use a 20
gallon capacity (approx.) fuel tank

mounted between
the
frame rails behind
the
rear axle.

The fuel tanks
are
basically
the
same
for
sedan, 2-seat

station wagon
and
pickup models except
for
filler neck

location
and
venting
(fig. 8).

All fuel tanks
are
vented
to the
atmosphere. Sedan

model tanks have
an
external vent hose and pipe assem-

bly
(fig. 11) and use a
non-vented fuel cap. Station wagon

and pickup model tanks
are
vented through
a
hose
and

vent pipe assembly
to the
filler neck
(fig. 8)
and
use a

vented, anti-surge type
gas cap. The
fuel caps
are two

different designs conforming
to SAE
standards
and are

not interchangeable.

The filler neck assembly
on
sedan models
is a
rear

fill design located behind
the
center
bar of the
bumper.
Station wagon
and
sedan pickup model filler neck assem-

blies
are
located
in
the left rear quarter panel.

The fuel pickup pipe
is
built integrally with
the
tank

gauge, located
at the
top-front center
of
the tank.
A
fine

mesh screen
is
located
at
the bottom-end
of the
fuel pick-

up pipe
to
prevent
the
entrance
of
foreign material into

the fuel system.

The sedan fuel tanks
are
held
in
place
by
two metal

straps attached individually
to the
underbody
at
each
end.

The straps hinge
at the
forward end and secure
the
tank

at
the
rear with
an
adjustable bolt
and nut
assembly.

The station wagon
and
pickup models have
a
frame

mounted fuel tank secured with straps
to
front and rear

supports.

The fuel lines, extending from fuel tank toiiuelpump,

are routed
on the
underside
of the
underbody along
the

right side
of the
vehicle opposite
the
single exhaust
sys-

tem.
The
fuel lines should occasionally
be
inspected
for
leaks,
kinks,
or
dents.
If
evidence
of
dirt
is
found
in the

carburetor
or
fuel pump
on
disassembly,
the
lines should

be disconnected
and
blown
out.
Check
the
fuel tank

strainer
for
damage
or

are of 5/16"

diameter tubing with beaded type ends
for
connections
of

hoses.

20 GALLON TANK

Fig.

—Corvette Fuel Tanks

The Corvette
is
equipped with
a
standard
20
gallon

(approx.) tank
or an RPO 36
gallon (approx.) fiberglass

tank
(fig. 21). The
tanks
are
installed
at the
very rear

of
the
vehicle, convenient
for
direct fuel filling into
the

tank.
The
tanks
are
held
in
place
by
two metal straps
at-

tached individually
to a
removable
gas
tank frame
sup-

port.
Two
guides
at the end of
the straps
are
adjustable

for securing
the
straps onto
the
tank support. The tank

support
is
secured
to the
frame rail with flat washers,

lockwashers, bolts
and
nuts.
The
tanks' rest
on six
felt

anti-squeak pads.
One pad
centers
on the
rear frame

crossmember
and one at
each side
on the
same cross-

member.
At the
same rear location two pads
are
placed

on
the
tank
at the
metal support strap (rear) attachment
location
and
another anti-squeak
pad
cemented
on the

support
at
the front
of
the tank.

The fuel tanks
are
