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.

3) Remove fuel pump assembly (1) from fuel tank (2).
INSPECTION
Check fuel pump assembly for damage.
Check fuel suction filter (1) for evidence of dirt and contami-
nation.
If present, replace or clean and check for presence of dirt in
fuel tank.
For operation or electrical circuit inspection by referring to
Section 6E1.
For inspection of fuel level gauge (2) by referring to Section
8.
Check tank pressure control valve referring to the following
procedures.
a) Air should pass through valve (2) smoothly from fuel vapor
line hose (3) “A” to “B” when blown hard.
b) Also, when vacuum pump (4) is connected to fuel vapor
hose and pump air through valve, air should pass from “B”
to “A”.
Special tool
(A) : 09917-47910
If air doesn’t pass through valve in Step a) or vacuum is main-
tained in Step b), replace fuel filter assembly (1).

WARNING:
Do not such air through fuel vapor line hose. Fuel vapor
inside valve is harmful.12

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.
“A” : Apply oil 5. O-ring 10. Fuel pressure regulator
1. Fuel filter assembly (including check valve) 6. Fuel level sensor (Fuel sender gauge) 11. Gasket
2. Grommet 7. Fuel pump 12. Fuel pump plate
3. Tube 8. Cushion Do not reuse.
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.

ENGINE FUEL 6C-13
INSTALLATION
1) Clean mating surfaces of fuel pump assembly (1) and fuel
tank.
2) Put plate (2) on fuel pump assembly (1) by matching the pro-
trusion of fuel pump assembly (3) to plate hole (4) as shown.
3) Install new gasket (2) and fuel pump assembly (1) with plate
(3) to fuel tank.
Tightening torque
Fuel pump assembly bolts (a) : 10 N·m (1.0 kg-m, 7.5 lb-ft)
4) Connect fuel breather hose (1), fuel vapor hose (2) and fuel
feed line (3) (pipe joint) to fuel pump assembly.
5) Install fuel tank (1) to vehicle. Refer to “FUEL TANK” in this
section.

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.
