a "U" bolt and at the same time secures the muffler and

pipe to the body.
The exhaust system mounting at the end of the tail pipe

secures the pipe to a bracket assembly and insulator at-

tached to an existing underbody bracket.

Replacement (Service)

1.
Cut the exhaust pipe near the muffler to allow suf-

ficient pipe for muffler replacement:

CAUTION: Before cutting the exhaust pipe

measure service muffler exhaust pipe extension

and make certain to allow 1-1/2" for engagement

of exhaust pipe into muffler extension.

ing all hardware.

NOTE:
If bracket mounting insulators (tire

carcass mountings) are fatigued, replace to in-

sure a secure exhaust system.

EXHAUST PIPE

Replacement

On V-8 engine exhaust models, if the left exhaust pipe
has to be replaced it will be necessary to replace both

the exhaust pipe and muffler with service replacement

parts.

to exhaust manifolds.

2.
Remove "U" bolt clamp retaining right exhaust pipe

to exhaust system and remove pipe.

3.
Using new manifold flange gaskets, install new ex-

haust pipe.

NOTE:
Check all clearances before tightening

hardware.

TAIL PIPE AND/OR RESONATOR

Replacement

1.
Install tail pipe to rear of muffler.

2.
Position tail pipe to obtain proper clearance to rear

spring bracket and underside of frame rail.

3.
Install tail pipe clamp over rear hanger and position

on pipe to maintain vertical position of insulator

without twist.

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.

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

GENERAL DESCRIPTION

The single exhaust system
cm
six* cylinder engine

models
(fig. 36)
consists
of an
exhaust pipe, extension,

muffler
and
tailpipe with necessary attaching brackets

and clamps.
On V-8
engine models with single exhaust

assemblies
(fig. 36) an
exhaust crossover pipe
is
added

to connect
the
right exhaust manifold
to the
system.
The

dual exhaust system available
on V-8
engine models
(fig.

37) includes
two
front exhaust pipes -with
or
without

resonators,
two
rear exhaust pipes, dual inlet-outlet

muffler, tailpipes and attaching hardware.

The assemblies
are
secured
to the
engine
at the ex-

haust manifolds,
to the
rear compartment pan reinforce-

ment ahead
of
axle
and
adjacent
to the gas
tank
at the
end
of the
tailpipe.
The
assemblies
are
suspended
on

brackets with insulators
for
rattle free operation.

The muffler
is an
all-welded construction with
a

•
capacity
for
muffling
the
noise
and at the
same time,

minimizing back pressure
for
maximum engine effici-

ency.
The
internal parts
are
electric welded
to
eliminate

premature failure
or
rattle.

The exhaust system center mounting
at the
muffler

location consists
of an
underbody bracket,
an
insulator

and
a
clamp.
The
clamp holds
the
muffler and tailpipe

with
a
"U" bolt and
at
the same time secures
the
muffler

and pipe
to the
body.

The exhaust system mounting
at the
end
of
the tailpipe

secures
the
pipe
to a
bracket assembly
and
insulator

attached
to an
existing underbody bracket.
