FUEL LINES

20 Gallon Tank

The fuel lines are conveniently located along the out-

side of the right frame rail (fig. 28). The lines extend
Fig.
26—Gasoline Tank (36 Gallon) Compartment Cover

from the fuel tank pickup at the bottom of the tank, along

the rear frame crossmember to the right frame rail,

extending through the rail at the kickup area and along the

top inside edge of the frame to the fuel pump, Flexible

hoses are located at the fuel tank pickup and at the fuel

pump.

36 Gallon Tank

The 36 gallon tank fuel lines are routed from the bot-

tom of both sides of the tank to the right frame rail

(fig. 20).

Maintenance

CAUTION: Always drain gasoline from the

complete fuel system including carburetor, fuel

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

cle is to be stored for any great length of time.

This precaution will prevent accumulation~ol

gum formation and resultant poor engine

performance.

. The fuel lines should occasionally be inspected for

leaks,
kinks or dents, especially when work has been

done on the underside of car or after the car has been

traveling over rough or stone roads at higher speeds.

If evidence of dirt is found in the carburetor or fuel pump

at disassembly, the lines should be disconnected and

blown put. Check the fuel tank strainer for damage or

omission.

Fuel lines are beaded-type ends for connection to

hoses and flared ends for secure metal-to-metal line

connections.

assembly is mounted on top of the tank and cannot be

removed for service without lowering the tank. The

upper filler neck assembly is routed through an opening

in the rear panel above the bumper and through the trunk

floor pan (fig. 33). The filler neck is not centered in the

rear panel but offset to the right to obtain the proper fill

rate.

The fuel pickup pipe is an integral part of the tank

meter unit^ located at the top front center of the tank. A

fine mesh screen is located at the bottom end of the fuel

pickup pipe to prevent the entrance of foreign material

into the fuel system.

FUEL LINES (Fig. 35)

The gasoline lines extending from fuel tank to fuel

pump,
are routed on the underside of the underbody, on

the right side, opposite the single exhaust system. The

lines extend from the fuel tank to the right side of the

engine to the fuel pump and over the front of the engine

to the carburetor.

Maintenance

CAUTION:

plete fuel
Always drain gasoline from corn-

including carburetor, fuel

pump and
fuel lines and fuel tank if the

vehicle is to be stored for any
eciable

length of time. This precaution will prevent

accumulation of gum formation and resultant

poor engine performance.

The fuel lines should occasionally be inspected for

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

carburetor or fuel pump disassembly, the lines should be

disconnected and blown out. Check the fuel tank strainer

for damage or omission. Fuel lines are of 5/16" diameter

tubing for regular installation with beaded-type ends for

connections to hoses and flared ends for secure line

connections.

GENERAL DESCRIPTION

The Chevelle instrument cluster assembly consists
of:

a speedometer;
a
fuel gauge;
a
generator,
an
engine
tem-

perature and an
oil
pressure indicator lamp, and includes

a clock
on
deluxe models.
On
super sport models,
am-

meter, coolant temperature
and oil
pressure gauges
re-

place
the
appropriate indicator lights. Except
for the

speedometer,
all of the
indicator lamps, instruments
and

gauges
of
these clusters may
be
serviced without remov-

ing
the
instrument cluster assembly from
the
vehicle.

In addition
to the
instrument indicator lamps,
a
brake

warning lamp
is
included
in the
cluster
as
standard

equipment.
The
indicator
is
connected
to the
parking
brake
and
brake pressure differential switches
and

serves
a
dual function.
It
lights when the parking brake

is applied
and
also when
the
brake pedal
is
applied,
if a

malfunction should occur
in the
brake system
due to a

loss
of
hydraulic pressure. Servicing
of the
hydraulic

pressure differential switch
is
covered
in
Section
5 of

this manual.

Regular maintenance
is not
required on the instrument

cjLuster
or its
components other than maintaining dean

and tight electrical connections, replacing defective parts

and keeping
the
speedometer cable properly lubricated.
