(8) Remove the screws and washers that attach the
filler tube to the inner panel and floor pan seals. Slide
both seals toward the center of the filler tube.
(9) Remove the 3 screws that attach the outer end
of the filler tube to the outer quarter panel skin.
(10) Withdraw the complete assembly (tube, seals,
vent tube and hose) into the luggage area and out of
the vehicle. Discard the filler tube to outer skin seal.
Inspect the condition of the tube to floor pan and in-
ner panel seals for signs of deterioration or damage.
Replace questionable seals with new ones at reassem-
bly.
Installation
Before installing the fuel gauge assembly, inspect
the filter on the end of the suction tube. If the filter
is plugged, install a new filter.
To install the fuel tank, refer to (Fig. 3), then pro-
ceed as follows:
(1)
Install a new gasket in the fuel gauge opening
recess, then slide the gauge into the tank. Align the
positioning tangs on the gauge with those in the tank.
Install the lock ring then tighten securely, using Tool
(2) Slide the fuel tank under the vehicle and up to
meet the filler tube. (Be sure a new grommet was in-
stalled in the tank). Engage the tank spout with the
filler tube, then work the tank onto the tube. Hold in
this position, then raise the retaining strap and
thread onto the
"J"
bolt. Install the attaching nut,
and tighten to
60
inch pounds.
(3) Reconnect the fuel line and the lead wire to the
fuel gauge unit.
(4)
Refill the fuel tank and test for leaks.
If the filler tube assembly was removed, it will be
necessary to install the tube assembly before install-
ing the tank. To install the filler tube assembly, refer
to (Fig. 3), then proceed as follows:
(1)
Place a new seal over the end of the filler tube
and a new rubber grommet in the tank. (Be sure and
test the vent hose connections, as a leak at this point
may allow fuel odor to enter the passenger compart-
ment.)
(2) Slide the filler tube assembly (tube, seals, vent
tube and hose) into position. Rotate the filler tube so
that it can enter the tank.
(3) Align the screw holes and install screws. Tight-
en securely.
(4)
Position both the inner panel to tube seal and
the tube to floor pan seal. Install the attaching screws
washers and tighten securely.
(5) Reaching through the access hole, reposition
the vent hose over the clip.
(6)
Reinstall the trim plate in the quarter panel.
(7)
Reinstall the rear floor pan filler and secure
( 8 )
Reinstall the spare tire cover and the floor mat.

Should it become necessary to remove a fuel tank
for repair or installation of a new tank, refer to (Fig.
4),
then proceed as follows:
(1) Drain the fuel tank (using the siphon method),
then disconnect the fuel line and the wire lead to the
gauge unit.
(2)
Remove the screw that attaches the filler tube
to the body panel, then, with a twisting motion, pull
the filler tube out of the tank. (If the tube is frozen
in the tank, use a rubber lubricant around the joint
and work into the rubber grommet.
(3) Remove the nut that holds the tank retaining
strap to the "J" bolt. Allow strap to hang, then drop
tank and remove from under the vehicle.
(4)
Remove the tank unit (gauge), using spanner
wrench Tool C-3582. Slide the gauge assembly out of
the fuel tank. Discard the gasket.
Installation
Before installing the fuel gauge, inspect the condi-
tion of the filter on the end of the suction tube. If the
filter is plugged, install a new filter.
To install the fuel tank, refer to (Fig.
4),
then pro-
ceed as follows:
(1) Install a new rubber grommet in the tank. In-
sert a new gasket in the fuel gauge opening recess,
then slide the gauge into the tank. Align the position-
ing tangs on the gauge with those in the tank. Install
the lockring, then tighten securely, using Tool C-
3582.
(2)
Slide the fuel tank under the vehicle. Raise the
tank far enough to engage the filler spout with the
opening in the rear panel.
(3) Push the tank toward the rear to fully engage
the filler spout in the opening.
(4)
Hold the fuel tank in this position, then place
the hold down strap in position; feeding the attaching
stud through the hole in the end of the strap. Install
the nut but do not tighten (2 or 3 threads).
(5) Guide the button head of the stud into the slot
in the frame and down into position. Move the tank
slightly back and forth; front and rear until the em-
bossed surface of the tank meshes with the embossed
surface of the floor pan. (Be sure the insulator is in
place.) With the tank held in this position, tighten the
strap bolt nut to
60
inch pounds.
CAUTION: Do
not exceed
60
inch pounds torque,
as additional pressure can distort the tank and may
cause leaks.
(6)
Slide the filler tube down into position through
the grommet with a twisting motion, until seated
firmly in the tank. Align the screw hole and install
