Precautions
Precautions on Fuel System ServiceS7RS0B1700001
WARNING!
Before attempting service of any type on fuel system, the following should be always observed in
order to reduce the risk of fire and personal injury.
• Disconnect negative cable at battery.
• Do not smoke, and place no smoking signs near work area.
• Be sure to have CO
2 fire extinguisher handy.
• Be sure to perform work in a well-ventilated area and away from any open flames (such as gas hot heater).
• Wear safety glasses.
• To relieve fuel vapor pressure in fuel tank, remove fuel filler cap from fuel filler neck and then
reinstall it.
• As fuel feed line is still under high fuel pr essure even after stopping engine, loosening or
disconnecting fuel feed line directly may cause dangerous spout of fuel. Before loosening or
disconnecting fuel feed line, make sure to relieve fuel pressure referring to “Fuel Pressure Relief
Procedure”.
• A small amount of fuel may be released when the fuel line is disconnected. In order to reduce the risk of personal injury, cover a shop cloth to the fitting to be disconnected. Be sure to put that cloth
in an approved container after disconnecting.
• Never run engine with fuel pump relay disconnected when engine and exhaust system are hot.
• Note that fuel hose connection varies with each type of pipe. Be sure to connect and clamp each hose correctly referring to “Fuel Hose Disconnecting and Reconnecting”.
After connecting, make sure that it has no twist or kink.
• When installing inje ctor or fuel feed pipe, lubr icate its O-ring with gasoline.

General Description
Fuel System DescriptionS7RS0B1701001
CAUTION!
This engine requires the unleaded fuel only.
The leaded and/or low lead fuel can result in
engine damage and reduce the effectiveness
of the emission control system.

The main components of the fuel system are fuel tank,
fuel pump assembly (with fuel filter, fuel level gauge, fuel
pressure regulator, fuel feed line and fuel vapor line.
For the details of fuel flow, refer to “Fuel Delivery System
Diagram”.
Fuel Delivery System DescriptionS7RS0B1701002
The fuel delivery system consists of the fuel tank, fuel
pump assembly (with built-in f uel filter and fuel pressure
regulator), delivery pipe, injectors and fuel feed line.
The fuel in the fuel tank is pumped up by the fuel pump,
sent into delivery pipe and injected by the injectors.
As the fuel pump assembly is equipped with built-in fuel
filter and fuel pressure regulator, the fuel is filtered and
its pressure is regulated before being sent to the feed
pipe.
The excess fuel at fuel pressure regulation process is
returned back into the fuel tank.
Also, fuel vapor generated in fuel tank is led through the
fuel vapor line into the EVAP canister.
For system diagram, refer to “Fuel Delivery System
Diagram”.

Fuel Pump DescriptionS7RS0B1701003
The fuel pump (1) is an in-tank type electric pump.
Incorporated in the pump assembly are;
a fuel filter (2) and a fuel pressure regulator (3) are
included and a fuel level gauge (4) is attached.
Addition of the fuel pressure regulator to the fuel pump
makes it possible to mainta in the fuel pressure at
constant level and ECM controls compensation for
variation in the intake manifold pressure.

Fuel Pressure InspectionS7RS0B1704001
WARNING!
Before starting the following procedure, be
sure to observe “Precautions on Fuel System
Service” in order to reduce the risk or fire
and personal injury.

1) Relieve fuel pressure in fuel feed line referring to
“Fuel Pressure Relief Procedure”.
2) Disconnect fuel feed hose from fuel delivery pipe.
3) Connect special tools and hose between fuel feed hose (1) and fuel delivery pipe as shown in figure,
and clamp hoses securely in order to ensure that no
leaks occur during checking.

Fuel Pressure Relief ProcedureS7RS0B1706003
CAUTION!
This work must not be done when engine is
hot. If done so, it may cause adverse effect to
catalyst.

NOTE
If ECM detects DTC(s) after servicing, clear
DTC(s) referring to “DTC Clearance in
Section 1A”.

1) Make sure that engine is cold.
2) Shift transaxle gear shift lever in “Neutral” (shift select lever in “P” range for A/T model), set parking
brake and block drive wheels.
3) Remove relay / fuse box cover.
4) Disconnect fuel pump relay (1) from relay / fuse box (2).
5) Remove fuel filter cap in order to release fuel vapor pressure in fuel tank, and then reinstall it.
6) Start engine and run it until engine stops for lack of fuel. Repeat cranking engine 2 – 3 times for about 3
seconds each time in order to dissipate fuel pressure
in lines. Fuel connections are now safe for servicing.
7) After servicing, connect fuel pump relay (1) to relay / fuse box and install re lay / fuse box cover.
Fuel Leakage Check ProcedureS7RS0B1706004
After performing any service on fuel system, check to
make sure that there are no fuel leakages as follows.
1) Turn ON ignition switch for 3 seconds (to operate fuel pump) and then turn it OFF.
Repeat this (ON and OFF) 3 or 4 times and apply
fuel pressure to fuel line until fuel pressure is felt by
hand placed on fuel feed hose.
2) In this state, check to see that there are no fuel leakages from any part of fuel system.
Fuel Lines On-Vehicle InspectionS7RS0B1706005
CAUTION!
Due to the fact that fuel feed line (1) is under
high pressure, use special care when
servicing it.

Visually inspect fuel lines for evidence of fuel leakage,
hose crack and deterioration or damage.
Make sure all cl amps are secure.
Replace parts as needed.
Fuel Pipe Removal and InstallationS7RS0B1706006
WARNING!
Before starting the following procedure, be
sure to observe “Precautions on Fuel System
Service” in order to reduce the risk or fire
and personal injury.

Removal
1) Relieve fuel pressure in fuel feed line according to “Fuel Pressure Relief Procedure”.
2) Disconnect negative cable at battery.
3) Disconnect fuel pipe joint and fuel hose (3) from fuel pipe (2) at the front and rear of each fuel pipe
referring to “Fuel Hose Disconnecting and
Reconnecting”.
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).
