5) Connect fuel feed hose (1) and vapor hose (2) to each pipe
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.

DISASSEMBLY AND REASSEMBLY
Disassemble and reassemble fuel pump assembly, noting the fol-
lowings.
When removing fuel level sensor (3), press snap-fit part (4)
and slide it in the arrow direction as shown in figure.
When installing fuel level sensor to housing, fit fuel level sen-
sor securely.

4. Housing 9. Bracket
CAUTION:
While removing fuel level gauge, do not contact resis-
tor plate (1) or deform arm (2). It may cause fuel level
gauge to fail.
When removing grommet from fuel tube or bracket sub
assembly, be very careful not to cause damage to
grommet installed section (sealed section in bore).
Should it be damaged, replace it with new one, or fuel
will leak from that part.

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
