HGSECaution
Cover the hose connection with rags to prevent splash
of fuel that could be caused by some residual pressure
in the fuel pipe line.
INSPECTIONN14GCAHl Check the hoses and the pipes for crack or damage.
l Check the fuel tank cap for malfunction.
l Check the fuel tank for deformation, corrosion or crack.
l Check the fuel tank for dust or foreign material.
NOTE
If the inside of the fuel tank is to be cleaned, use any one ofthe following:
(1) Kerosene
(2) Trichloroethylene
(3) A neutral emulsion type detergent
OVERFILL LIMITER (TWO-WAY VALVE)
Set a hand vacuum pump at inlet side or outlet side; the valve
is good if, when a negative pressure (vacuum) is applied, air
flows after a slight negative pressure is initially maintained.

(1) When installing the fuel filter, first temporarily install the
filter 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.

Apply engine oil to the hose union.
Insert the hose, being careful not to damage the O-ring, andtighten 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.

SERVICE ADJUSTMENT PROCEDM%,&ACCELERATOR CABLE
CNSPECTION AN&I ”ADJUSTMENT
For models equipped with the auto-cruise control systemreferto
P.14-136.(1) Turn air conditioner and lights OFF.
Inspect and adjust at no load.
2) Warm engine until stabilized at idle.
3) Confirm idle speed is at prescribed rpm.
4) Stop engine (ignition switch OFF).
5) Confirm there are no sharp bends in accelerator cable.
6) Check inner cable for correct slack.
7) If there is too much slack or no slack, adjust play by the
following procedures.
@ 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.@
Loosen the adjusting bolts on the air intake plenum, andthen secure the outer cable so that the free play of the
inner cable will be the standard value.
Standard value:
jlr
l-2 mm (.04-.08 in.) \. *
3-5 mm (.12-.20 in.)
NOTEIf there is excessive 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.
(8) After adjusting, confirm that throttle valve fully opens and
closes by operating pedal.
(9) Adjust accelerator cable play and confirm throttle lever
stopper touches the idle switch.
ACCELERATOR SWITCH INSPECTION AND
ADJUSTMENT
NlWlEB(1) After warming up the engine, check to be sure that the
accelerator 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
2-6 mm
(.08-.24 ‘in.)
(3) If the distance (A in the figure) is not within the standard
value, adjust it by using the adjusting bolt.
