GENERAL DESCRIPTION
The main components of the fuel system are fuel tank, fuel pump assembly (with fuel filter, fuel level gauge, fuel
pressure regulator and tank pressure control valve), fuel/vapor separator fuel feed line and fuel vapor line.
For the details of fuel flow and fuel vapor flow, refer to “GENERAL DESCRIPTION” in Section 6E. WARNING:
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).
CAUTION:
The engine of this vehicle requires the use of unleaded fuel only. Use of leaded and/or low lead fuel
can result in engine damage and reduce the effectiveness of the emission control system.

4) Mark the location of clamps (1) on fuel pipes (2), so that the
clamps can be reinstalled to where they were.
5) Remove pipes (2) with clamp (1) from vehicle.
6) Remove clamp (1) from pipes (2).
INSTALLATION
1) Install clamps to marked location on pipes. If clamp is
deformed or its claw is bent or broken, replace it with new
one.
2) Install pipes with pipe clamps to vehicle.
3) Connect fuel hoses and pipes to each pipe.
4) With engine OFF, turn ignition switch to ON position and
check for fuel leaks.
FUEL FILLER CAP
INSPECTION
Remove cap (1), and check gasket for even filler neck imprint,
and deterioration or any damage. If gasket (2) is in malcondition,
replace cap.

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.
NOTE:
If cap requires replacement, only a cap with the same fea-
tures should be used. Failure to use correct cap can
result in critical malfunction of system.

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.
