6) Disconnect fuel pipe joint and fuel hoses from pipes.
For quick joint, disconnect it as follows :
a) Remove mud, dust and/or foreign material between pipe
and joint by blowing compressed air.
b) Unlock joint (1) lock by inserting special tool between pipe

Special tool
(A) : 09919-47020
c) Disconnect joint from pipe.
7) Support fuel tank (1) with jack (2) and remove its mounting
bolts.
8) Lower fuel tank a little as to disconnect wire harness at con-
nector (1), then remove fuel tank.
INSPECTION
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.WARNING:
A small amount of fuel may be released after the fuel
hose is disconnected. In order to reduce the chance of
personal injury, cover the hose and pipe to be discon-
nected with a shop cloth. Be sure to put that cloth in an
approved container when disconnection is completed.

as shown in figure and clamp them securely.
6) Connect negative cable at battery.
With engine OFF, turn ignition switch to ON position and
check for fuel leaks.
FUEL PUMP ASSEMBLY
REMOVAL
1) Remove fuel tank from vehicle. Refer to “FUEL TANK”.
2) Disconnect fuel breather hose (1), fuel vapor hose (2) and
pipes from fuel pump assembly.
When disconnecting joint of fuel feed line (3) from pipe,
unlock joint by inserting special tool between pipe and joint
lock first.
Special tool
(A) : 09919-47020 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).
WARNING:
Refer to the PRECAUTIONS at the beginning of ON-VEHI-
CLE SERVICE.

For vehicles equipped with Supplemental Restraint (Air Bag) System :
Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” in air bag system section before performing service
on or around the air bag system components or wiring. Failure to follow WARNINGS could result in
unintentional activation of the system or could render the system inoperative. Either of these two
conditions may result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system
may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:
Whether the following system (parts) are used in the particular vehicle or not depends on vehicle
specifications. Be sure to bear this in mind when performing service work.
EGR valve
Heated oxygen sensor(s) or CO adjusting resistor
Three way catalytic converter
Immobilizer indicator lamp
Knock sensor

ACCELERATOR CABLE ADJUSTMENT
With accelerator pedal depressed fully (1), check clearance
between throttle lever (2) and lever stopper (3) (throttle body)
which should be within following specification.
If measured value is out of specification, adjust it to specification
with cable adjusting nut (4).
