bracket retaining nuts and remove the mounting
brackets from the mounting studs. (12) Remove the fuel tank retaining bolts and
maneuver the fuel tank from the vehicle. Installation is a reversal of the removal procedure
with attention to the following points:

(1) When installing the fuel tank, ensure that the
fuel pump wiring harness is directed through the
aperture in the floor. (2) Install the stabilizer bar mounting
bracket
bolts and tighten to the specified torque. Refer to the
Rear Suspension section.
(3) Using a new gasket, install the intermediate
exhaust pipe to the catalyti c converter ensuring that
the earth wire terminal is installed and tighten the
bolts securely. (4) Connect the fuel filler neck hose, the fuel
check valve hose and the breat her hose ensuring that
they are secured firmly. (5) Tighten the fuel tank drain plug to the
specified torque. (6) Connect the fuel hoses to the fuel pump,
using the marks made during removal to ensure
correct installation. (7) Install the fuel pump wiring harness and the
rubber grommet to the fuel pump cover plate. Install
the cover plate and tighten the retaining bolts se-
curely.
(8) Connect the fuel pump wiring connector
securely. (9) Check for fuel leaks as previously described.

AIR CLEANER ASSEMBLY
To Renew Element
The procedure for renewing the air cleaner ele-
ment is covered in the Engine Tune-up section.

To Remove and Install — 1.8 Liter Engine
(1) Disconnect the negative battery terminal.
(2) Release the air intake hose retaining clamps,
disconnect the hose from the air cleaner upper
housing and the throttle body and remove the hose. (3) Remove the screw securing the air cleaner
intake duct to the front panel mounting bracket. (4) Remove the hexagon head screws retaining
the air cleaner mounting bracket to the right hand
inner mudguard and remove the air cleaner from the
engine compartment. (5) Release the upper housing retaining clips,
separate the upper housing from the lower housing
and remove the element. (6) Remove the air cleaner intake duct retaining
screw and disconnect the duct from the lower air
cleaner housing. (7) If necessary, remove the bolts securing the
mounting bracket to the ai r cleaner lower housing and
separate the mounting bracket from the housing. (8) Thoroughly clean the upper and lower hous-
ings in cleaning solvent and check for cracks, splits or
damage that would allow unfiltered air to enter the
engine. Renew any components as necessary.
Installation is a reversal of the removal procedure
with attention to the following points:

(1) Ensure that the r ubber insulators are in-
