INSTALLATION
Note the following, and install in the reverse order of removal.

Surely clamp fuel hoses and insert hose to the length below.

Be sure hose clamp is not placed on swelled area of fuel tube.

Tighten clamps of fuel filler hose so that the remaining length of screw thread becomes 8 to12 mm (0.31
to 0.47 in) on tank side and 5.7 to 9.7 mm (0.224 to 0.382 in) on fuel filler tube side.

To connect quick connector, refer to FL-7, "Quick Connector" .
INSPECTION AFTER INSTALLATION
Use the following procedure to check for fuel leaks.
1. Turn ignition switch “ON” (with engine stopped), and check connections for leakage by applying fuel pres-
sure to fuel piping.
2. Start engine and check for fuel leaks at the fuel system tube and hose connections.

After removing/installing rear suspension assembly, make sure to adjust wheel alignment and then, adjust
neutral position of steering angle sensor. Refer to RSU-5, "
Wheel Alignment Inspection" and BRC-6,
"Adjustment of Steering Angle Sensor Neutral Position" .

NOTE:
Before measurement, move ball joint at least ten times by hand to check for smooth movement.

Hook spring scale at ball stud. Confirm spring scale measure-
ment value is within the specifications when ball stud begins
moving.

If it is outside the specified range, replace transverse link
assembly.

Attach mounting nut to ball stud. Check that rotating torque is
within the specifications with a preload gauge (SST).

If it is outside the specified range, replace transverse link
assembly.

Precautions for Fuel (Unleaded Premium Gasoline Required)AAS000GS
Use unleaded premium gasoline with an octane rating of at least 91 AKI (Anti-Knock Index) number (Research
octane number 96).
If unleaded premium gasoline is not available, unleaded regular gasoline with an octane rating of at least 87
AKI number (Research octane number 91) can be used, but only under the following precautions:

have the fuel tank filled only partially with unleaded regular gasoline, and fill up with unleaded premium
gasoline as soon as possible.

avoid full throttle driving and abrupt acceleration.
However, for maximum vehicle performance, the use of unleaded premium gasoline is recommended.
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Using a fuel
other than that specified could adversely affect the emission control devices and systems, and could
also affect the warranty coverage validity.
Precautions for Multiport Fuel Injection System or Engine Control SystemAAS000F1

Before connecting or disconnecting any harness connector for
the multiport fuel injection system or ECM:
Turn ignition switch to “OFF” position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.

Before disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.

Be careful not to jar components such as ECM and mass air
flow sensor.
Precautions for HosesAAS000F2
HOSE REMOVAL AND INSTALLATION

To prevent damage to rubber hose, do not pry off rubber hose
with tapered tool or screwdriver.

To reinstall the rubber hose securely, make sure that hose inser-
tion length and orientation is correct. (If tube is equipped with
hose stopper, insert rubber hose into tube until it butts up
against hose stopper.)
