Corvette Powerglide Control Lever

and Bracket Assembly

Powerglide control lever and bracket assembly is a

straight line shift type, mounted to the floor of the body

rather than the transmission extension as in the past.

Shifting from one detent position to another is done by

depressing a round button located in the center of the

spherical' shift lever knob. If disassembly of this control

lever and bracket assembly is necessary, refer to Figure

11PG for parts breakdown and relative positioning for

assembly.

If disassembly of this control lever and bracket as-

sembly is necessary, refer to Figure 12PG for parts

break down and relative positioning for assembly.
Throttle Valve Linkage Adjustment

L-4 and L-6 Models

With accelerator pedal depressed, Bell Crank on L-4

and L-6 models must be at wide open throttle position.

Dash Lever must be 1/64"-1/16" off Lever Stop and

Transmission Lever must be against transmission in-

ternal stop.

GENERAL DESCRIPTION

All Sedan models (fig. 1) use a 24 gallon capacity

(approx.) fuel tank mounted between the frame rails

behind the rear axle. The fuel tanks are held in place

by two straps attached individually to the underbody at

each end. The strap? hinge at the forward end and secure

the tank at the rear with a nut and bolt. Anti-squeak

material is cemented to the tank at the strap locations.
A vent line from the forward-right side of tank extends

over a clip on the upper portion of wheelhouse.

The station wagon fuel tank has a 24 gallon capacity

(approx.). The tank is located at the back of the left rear

quarter wheelhouse area. The front of the tank is en-

closed with a protective shield (fig. 1).

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.

Draining Tank

The absence
of a
drain plug
in the gas
tanks makes
it

necessary
to
siphon fuel from
the
tank when draining

previously outlined under Chevrolet Models
in
this

section.

FUEL LINES

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
omission. Fuel lines
are of 5/16"

diameter tubing with beaded type ends
for
connections
of

hoses.

FUEL TANK VENT LINE

Sedan model 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 as shown in Figure 8. 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

gas tank is not vented at the cap; therefore, it
is necessary to be assured that the vent line is

free from dirt, etc., and that the gas tank vent

line is open at all times. If gasoline fumes are

detected, the rubber grommet should be checked.

Station wagon and pickup model tanks are vented from

the tank to the filler neck (fig. 9) and use a vented cap.

The vent outlet pipe on the tank is connected to the vent

inlet pipe on the filler neck by a rubber hose. The hose

is secured with two wire clamps.

Fig.
13—Single Exhaust System

The single exhaust system used on all six cylinder

engine models consists of an exhaust pipe, muffler and

tail pipe (fig. 13), An exhaust crossover pipe is added on

V-8 engine single exhaust models to connect the exhaust

manifolds to the system. A dual exhaust system, availa-

ble on V-8 engine models includes two exhaust pipes,

mufflers, and tail pipes and attaching hardware (fig. 14).

All systems are suspended on brackets with insulators

for rattle free operation.

The mufflers are a seam rolled construction with spot

welded baffles, with a capacity for muffling the exhaust

and at the same time, minimizing back pressure for
maximum engine efficiency. The internal parts of the

muffler are spot welded in position while external parts

are electric arc-welded to eliminate a chance of pre-

mature failure or rattle.

The exhaust system center mounting at the muffler lo-

cation (fig. 13) consists of an underbody bracket, an insu-

lator and a clamp. The clamp holds the muffler and tail

pipe 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 tail pipe

secures the pipe to a bracket assembly and insulator at-

tached to an existing underbody bracket (fig. 13).
