CAUTION:
q When removing accelerator wire, make a mark to indicate lock nut's initial position. MA
q Check that throttle valve opens fully when accelerator pedal is fully depressed. Also check that it
returns to idle position when pedal is released.
q Check accelerator control parts for improper contact with any adjacent parts. EM
q When connecting accelerator wire, be careful not to twist or scratch its inner wire.
q Refer to EL section (``AUTOMATIC SPEED CONTROL DEVICE'') for ASCD wire adjustment.

WARNING:
When replacing fuel line parts, be sure to observe the following:
q Put a ``CAUTION: INFLAMMABLE'' sign in workshop.
q Do not smoke while servicing fuel system. Keep open flames and sparks away from work area.
q Be sure to furnish the workshop with a CO2 fire extinguisher.
CAUTION:
q Before removing fuel line parts, carry out the following procedures:
a. Put drained fuel in an explosion-proof container and put lid on securely.
b. Release fuel pressure from fuel line. Refer to MA section (``Changing Fuel Filter'').
c. Disconnect battery ground cable.
q Always replace O-rings with new ones.
q Do not kink or twist hose and tube when they are installed.
q Do not tighten hose clamps excessively to avoid damaging hoses.
q After installation, run engine and check for fuel leaks at connections.

After connecting quick connector, make sure the connection is
firmly made using the following method.
q Pull on the fuel tube and connector to make sure they are firmly
connected.
q Start the engine, increase engine speed and verify that there
are no leaks.

``Removal,'' FE-5.
2. Remove the six screws.
3. Remove fuel gauge retainer and fuel gauge. ST
4. Remove fuel pump with bracket while lifting the pawl of the fuel
pump bracket upward.

q Install fuel gauge as shown.
CAUTION: HA
q Tighten bolts to specified torque.
:2.0 - 2.5 N m (0.20 - 0.26 kg - m, 17.4 - 22.6 in - lb)

EXHAUST SYSTEM
CAUTION:
q Always replace exhaust gaskets with new ones when reassembling.
q With engine running, check all tube connections for exhaust gas leaks, and entire system for
unusual noises.
q Check to ensure that mounting brackets and mounting insulators are installed properly and free
from undue stress. Improper installation could result in excessive noise or vibration.
q Discard any heated oxygen sensor which has been dropped from a height of more than 0.5 m (19.7
in) onto a hard surface such as a concrete floor; use a new one.
q Before installing new oxygen sensor, clean exhaust system threads using oxygen sensor thread
cleaner Tool J-43897-18 or J-43897-12 and approved anti-seize lubricant.
q Do not overtorque the oxygen sensor. Doing so may cause damage to the oxygen sensor, result-
ing in the MIL coming on.
