Fuel Filter ReplacementS7RS0B0206011
Fuel filter is installed in fuel pump assembly in fuel tank.
Replace fuel filter or fuel  pump assembly with new one, 
referring to “Fuel Pump Assembly Removal and 
Installation in Section 1G” for proper procedure.
Fuel Tank InspectionS7RS0B0206012
Check fuel tank damage, cracks, fuel leakage, corrosion 
and tank bolts looseness.
If a problem is found, repair or replace.
PCV Valve InspectionS7RS0B0206013
Check crankcase ventilation hose and PCV hose for 
leaks, cracks or clog, and PCV valve for stick or clog. 
Refer to “PCV Valve Inspection in Section 1B” for PCV 
valve checking procedure.
Fuel Evaporative Emission Control System 
Inspection
S7RS0B0206014
1) Visually inspect hoses for cracks, damage, or  excessive bends. Inspect a ll clamps for damage and 
proper position.
2) Check EVAP canister for operation and clog,  referring to “EVAP Canister  Inspection in Section 
1B”.
If a malfunction is found, repair or replace.
Brake Discs and Pads InspectionS7RS0B0206015
1) Remove wheel and caliper but don’t disconnect  brake hose from caliper. 2) Check disc brake pads and discs for excessive wear, 
damage and deflection. Replace parts as necessary. 
For details, refer to “Front Disc Brake Pad Inspection 
in Section 4B”, “Front Brake Disc Inspection in 
Section 4B”, “Rear Disc Brake Pad Inspection in 
Section 4C” and/or “Rear Brake Disc Inspection in 
Section 4C”.
Be sure to torque caliper pin bolts to specification.
Brake Hoses and Pipes InspectionS7RS0B0206016
Perform this inspection where these is enough light and 
use a mirror as necessary.
• Check brake hoses and pipes for proper hookup, leaks, cracks, chafing and other damage.
• Check that hoses and pipes are clear of sharp edges  and moving parts.
Repair or replace any of these parts as necessary.
CAUTION! 
After replacing any brake pipe or hose, be 
sure to carry out  air purge operation.

CAUTION! 
• When connecting joint, clean outside surfaces of pipe where joint is to be 
inserted, push joint into  pipe till joint lock 
clicks and check to ensure that pipes are 
connected securely, or fuel leak may 
occur.
• Never let the fuel hoses touch the ABS  sensor harness (if equipped).
 
1) If parts have been removed from fuel tank, install  them before installing  fuel tank to vehicle.
2) Raise fuel tank (1) with jack (2) and connect fuel  pump connector (3), ground wire (4) and clamp wire 
harness.

6) Install exhaust center pipe referring to “Exhaust Pipe  and Muffler Removal and Installation in Section 1K”.
7) Connect negative cable at battery.
8) With engine OFF, turn ignition switch to ON position  and check for fuel leaks.
Fuel Tank InspectionS7RS0B1706014
After removing fuel tank, check hoses and pipes 
connected to fuel tank for leaks, loose connections, 
deterioration or damage. Also check fuel pump 
assembly gaskets for leaks, visually inspect fuel tank for 
leaks and damage.
Replace any damaged or malconditioned parts.

Fuel Tank Purging ProcedureS7RS0B1706015
WARNING! 
• Before starting the following procedure, be sure to observe “Precautions on Fuel 
System Service” in order to reduce the risk 
or fire and personal injury.
• This purging procedure will not remove all  fuel vapor.
Do not attempt any repair on tank using 
heat of flame as an explosion resulting in 
personal injury could occur.
 
CAUTION! 
Never remain water in fu el tank after washing, 
or fuel tank inside will get corrosion.
 
The following procedure are used for purging fuel tank.
1) After removing fuel tank, remove all hoses, pipes  and fuel pump assembly from fuel tank.
2) Drain all remaining fuel from tank.
3) Place fuel tank to flushing area.
4) Fill tank with warm water  or tap water, and agitate 
vigorously and drain. Repeat this washing until 
inside of tank is clean. Replace tank if its inside is 
rusty.
5) Completely flush out rema ining water after washing.
Fuel Pump On-Vehicle InspectionS7RS0B1706016
WARNING! 
Before starting the following procedure, be 
sure to observe “Precautions on Fuel System 
Service” in order to reduce the risk or fire 
and personal injury.
 
NOTE
The fuel pressure regulator is incorporated 
with the fuel pump assembly so individual 
inspection of it is impossible.
 
1) Remove filler cap and turn  ON ignition switch (2). 
Then fuel pump operating sound should be heard 
from fuel filler (1) for about 2 seconds and stop. Be 
sure to reinstall fuel  filler cap after checking.
If the check result is not  satisfactory, go to “Fuel 
Pump and Its Circuit Check in Section 1A”. 2) Turn OFF ignition switch and leave over 10 minutes 
as it is.
3) Fuel pressure should be felt at fuel feed hose (1) for  about 2 seconds after ignition switch ON.
If fuel pressure is not  felt, go to “Fuel Pressure 
Check in Section 1A”.
Fuel Pump Assembly Removal and InstallationS7RS0B1706017
WARNING! 
Before starting the following procedure, be 
sure to observe “Precautions on Fuel System 
Service” in order to reduce the risk or fire 
and personal injury.
 
Removal
1) Remove fuel tank from vehicle. Refer to “Fuel Tank  Removal and Installation”.
2) Disconnect fuel feed pipe (1) from fuel pump  assembly (2) referring to “Fuel Hose Disconnecting 
and Reconnecting”.
