SERVICE POINTS OF REMOVALMlSKBAMl
1. REMOVAL OF EYE BOLT
Remove the eye bolt while holding the fuel filter nut
securely.
Caution
Cover the hose connection with rags to prevent splash
of fuel that could be caused by some residual pressure
in the fuel pipe line.
3. REMOVAL OF FUEL FILTER (1) Loosen the main pipe flare nut while holding the fuelfilter nut securely.
(2) Remove the fuel filter mounting bolts, and then remove the fuel filter from the bracket.
INSPECTIONMlOKCABl
l Check the hose and pipes for cracks, bend, deformationand clogging.
lCheck the evaporative emission canister for clogging.
l Check the fuel filter for clogging and damage.
SERVICE POINTS OF INSTALLATIONMlJKDAPl
6. INSTALLATION OF FUEL VAPOR HOSE/4. FUEL RE-
TURN HOSE
(1) If the fuel pipe has a stepped part, connect the fuel
hose to the pipe securely, up to the stepped part, as
shown in the figure.
(2) If the fuel pipe does not have a stepped part, connect the fuel hose to the pipe securely, so that it is the
standard value.
3. INSTALLATION OF FUEL FILTER (1) When installing the fuel filter, first temporarily install thefilter to the filter bracket; then insert the main pipe at
the connector part of the filter, and manually screw in
the main pipe’s flare nut.
(2) Holding the fuel filter nut, tighten the fuel main pipe’s
flare nut and eye bolt at the specified torque. Then
tighten the filter to the bracket.
TSB Revision 2. INSTALLATION OF HIGH PRESSURE FUEL HOSE
Apply engine oil to the hose union.
Insert the hose, being careful not to damage the O-ring, and
tighten securely.
Caution
Because there is high pressure applied between the
fuel pump and the injection mixer, be especially sure
that there is no fuel leakage in this area.

ENGINE CONTROL - Service Adjustment Procedures13-329
SERVICE ADJUSTMENT PROCEDW,E,t&
ACCELERATOR CABLE INSPECTION AND
ADJUSTMENT
For models equipped with the auto-cruise control system, refer
to P. 13-398.
(1) Confirm there are no sharp bends in accelerator cable.
(2) On models with an SOHC engine, turn the ignition switch to the ON position (without starting the engine) and leave
in that condition for approximately 15 seconds.
(3) Loosen the adjusting bolts on the intake manifold plenum, and then secure the outer cable so that the free play of theinner cable will be the standard value.
Standard value:
>
1 - 2 mm (.04- .08
in.)
-a/T>3-5 mm (.12-.20 in.)
NOTE
If there is excessrve play of the accelerator cable, the
vehicle speed drop (“undershoot”) when climbing a slope will
be large.
If there is no play (excessive tension) of the accelerator
cable, the idling speed will increase.
(4) After adjusting, confirm that throttle valve fully opens and closes by operating pedal.
(5) Adjust accelerator cable play and confirm throttle lever
stopper touches the closed throttle position switch.

ACCELERATOR SWITCH INSPECTION AND
ADJUSTMENTM13FTBBa
(1) After warning up the engine, check to be sure that theaccelerator switch is ON when the accelerator pedal is in
the free condition. If there is a malfunction, adjust by using
the adjusting bolt.
(2) Press the accelerator pedal by hand until the accelerator switch switches from ON to OFF and confirm that the
amount of pedal movement (A in the figure) is within the
standard value range.
Standard value: Accelerator switch switching point
4-8 mm (.16-.31 in.)
(3) If the distance (A in the figure) is not within the standard value, adjust it by using the adjusting bolt.
