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. Remove fuel tank assembly (9). Refer to “Fuel Tank
Removal" in this section.
2. Disconnect the quick connector (6) of the fuel tube from fuel gauge unit.
3. Disconnect the quick connector (10) of the evapo tube from fuel gauge unit.



140R100035
3. Remove the retainer ring (7) from the fuel tank with the
removal tool 5-8840-2602-0.
4. Remove slowly the fuel gauge unit (4) from the fuel tank as
no bend float arm.
NOTE: Cover opening for the fuel gauge unit on fuel tank to
prevent any dust entering.
5. Discard fuel gauge unit seal (8) because it cannot be
reusable.


Installation
1. Clean the seal surface of the fuel tank and the fuel gauge unit.
NOTE: If there is dust on the seal surface, it becomes cause o
f
fuel leak.
2. Install the new fuel gauge unit seal (8) to opening of the fuel tank as along the groove.
3. Install slowly the fuel gauge unit (4) into the fuel tank as no bend float arm.
4. Set flange of the fuel gauge unit on fuel gauge unit seal as
mating convexity of the fuel gauge unit and reentrant of the
fuel tank.
5. Lock slowly the retainer ring (7) to the fuel tank with the
remover tool 5-8840-2602-0.
6. Connect the quick connector (10) of the evapo tube from fuel gauge unit.
7. Connect the quick connector (6) of the fuel tube to to gauge
unit.
NOTE: Pull off the left ckecker of the fuel pipe.
NOTE: Refer to “Fuel Tube/Quick Connector Fittings” in this
section when performing any repairs.

2. For removal of the quick connector, hold the quick
connector in one hand, and pull out the connector with the
other hand while pressing the square relieve button of the
connector, as illustrated.
NOTE: Do not use tools of any kind. Only use bare hands
when disconnecting the connector. Use a lubricant (light oil)
and/or push and pull the connector until the pipe is
disconnected.





140R100028
Cover the connectors that was removed with a plastic bag,
to prevent dust or rain water from entering.






140R100036
Reuse of Quick–Connector
• Replace the port and connector if scratch, dent or crack is
found.
• Remove any dirt build up on the port when installing the
connector. Replace the connector, if there is any forms o
f
rust, dent, scratch.
• After cleaning the port, insert it straight into the connecto
r
until it clicks. After it clicks, try pulling at 49N (5kgf) it out to
make sure that it is not drawn and is securely locked.


Assembling Advice
By applying engine oil or light oil to the pipe, port makes pipe
assembly easier. The pipe assembly should take place
immediately after applying oil (to prevent dust from sticking to
the pipe surface – which may decrease sealing ability). Test/Inspection After Assembling
1. Reconnect the battery negative cable.
2. Start the engine and observe the engine idle speed. The presence of dirt in the fuel system may affect the fuel
injection system.
3. Check for fuel leakage from the connector.

crankshaft pulley TDC line aligned with the timing
mark.
Note:
If the check hole cover is reinstalled with the lock bolt
still in place, the crank pulley will not turn.
