Reuse of Quick–Connector
(Delivery Pipe)
Replace the pipe and connector if scratch, dent or
crack is found.
Remove mud and dust from the pipe and make sure
that the end including spool is free of defects, such as
scratch, rust, and dent, which may cause poor
sealability. If defective, replace with a new pipe.
If the retainer removed according to the removal step
above is attached to the pipe, clean and insert it
straight into the quick-connector till it clicks. After it
clicks, try pulling it out to make sure that it is not drawn
and is securely locked.
NOTE: The retainer, once removed from the pipe, cannot
be reused. Just replace with a new retainer. Insert the
new retainer into the connector side until it clicks, and
connect the pipe as inserting it into the retainer until it
clicks.

(Return Pipe)
Replace the pipe and connector if scratch, dent or
crack is found.
Remove mud or dust from the pipe and make sure
that the end including spool is free from defects, such
as scratch, rust, and dent, which may cause poor
sealability. If defective, replace with a new pipe.
After cleaning the pipe, insert it straight into the
connector until it clicks. After it clicks, try pulling it out
to make sure that it is not drawn and is securely
locked.

Assembling Advice
Application of engine oil or light oil to the pipe facilitates
connecting work. The work should be started immediately
after lubrication, since dust may stick to the pipe surface
to cause poor sealability if a long time passes after
lubrication.
Test/Inspection After Assembling
1. Reconnect the battery negative cable.
2. Turn the ignition key to the “ON” position and check
pump startup sound. As the pump is actuated to raise
fuel pressure, check and see fuel leak from the piping
system.
3. Make sure of no fuel leakage by conducting the above
fuel leak check a few times.
4. Start the engine and make sure of stable idling speed
and normal vehicle run.The entry of dust during the
work may sometimes affect the fuel injection system.

Removal
CAUTION: When repair to the fuel system has been
completed, start engine and check the fuel system
for loose connection or leakage. For the fuel system
diagnosis, see Section “Driveability and Emission”.
1. Disconnect battery ground cable.
2. Loosen fuel filler cap.
3. Drain fuel.
Tighten drain plug to the specified torque after
draining fuel.
Torque: 20 Nꞏm (2.0 Kgꞏm/14 lb ft) — M8
4. Wiring connector
Disconnect wiring connector(1) from the unit.
5. Fuel gauge unit
Remove the fixing screws, then the fuel gauge
unit(2).
NOTE: After removing fuel gauge unit, cover fuel tank to
prevent any dust entering
Installation
1. Fuel gauge unit(2).
2. Wiring connector(1).
Connect the wiring connector to the fuel gauge unit.
Fill the tank with fuel and tighten fuel filler cap.
Connect battery ground cable.

Fuel Filler Cap
General Description
Fuel filler cap includes vacuum valve and pressure valve.
In case any high vacuum and any high pressure happen in
tank, each valve works to adjust the pressure to prevent
the tank from being damaged.

Inspection
Check the seal ring in the filler cap for presence of any
abnormality and for seal condition.
Replace the filler cap, if abnormal.
CAUTION: The fuel filler cap valves have
characteristics.
A defective valve, no valve at all or a valve with the
wrong characteristics will do a lot of harm to engine
operating characteristics; be sure to use the same
fuel filler cap as installed in this vehicle.

Spark Plug
Removal
1. Remove spark plugs.
Inspection and Repair
The spark plug affects entire engine performance and
therefore its inspection is very important.
Check electrode and insulator for presence of cracks,
and replace if any.
Check electrode for wear, and replace if necessary.
Check gasket for damage, and replace if necessary.
Measure insulation resistance with an ohmmeter, and
replace if faulty.
Adjust spark plug gap to 1.0 mm (0.04 in) 1.1 mm
(0.043 in).
Check fuel and electrical systems if spark plug is
extremely dirty.
Use spark plugs having low heat value (hot type plug)
if fuel and electrical systems are normal.
Use spark plugs having high heat value (cold type
plug) if insulator and electrode are extremely burned.
Sooty Spark Plugs
Much deposit of carbon or oil on the electrode and
insulator of spark plug reduces the engine performance.
Possible causes:
Too rich mixture
Presence of oil in combustion chamber
Incorrectly adjusted spark plug gap
Burning Electrodes
This fault is characterized by scorched or heavily oxidized
electrode or blistered insulator nose.
Possible causes:
Too lean mixture
Improper heat value
Measuring Insulation Resistance
Measure insulation resistance using a 500 volt
megaohm meter.
Replace spark plugs if measured value is out of
standard.
Insulation resistance: 50 M
or more
011RS010
Cleaning Spark Plugs
Clean spark plugs with a spark plug cleaner.
Raise the ground electrode to an angle of 45 to 60
degrees. If electrode is wet, dry it before cleaning.
After spark plug is thoroughly cleaned, check
insulator for presence of cracks.
Clean threads and metal body with a wire brush.
File the electrode tip if electrode is extremely worn.
Bend the ground electrode to adjust the spark plug
gap.

Installation
1. Spark plugs
Tighten spark plugs to the specified torque.
