General PrecautionsEBS011T7
WARNING:
When replacing fuel line parts, be sure to observe the following.

Put a “CAUTION: INFLAMMABLE” sign in the workshop.

Be sure to work in a well ventilated area and furnish workshop with a CO2 fire extinguisher.

Do not smoke while servicing fuel system. Keep open flames and sparks away from the work area.
CAUTION:

Use gasoline required by the regulations for octane number. Refer to GI-5, "Precautions for Fuel" .

Before removing fuel line parts, perform the following procedures:
–Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in
safe area.
–Release fuel pressure from the fuel lines. Refer to EC-49, "FUEL PRESSURE RELEASE" (WITH
EURO-OBD) or EC-562, "
FUEL PRESSURE RELEASE" (WITHOUT EURO-OBD).
–Disconnect the battery cable from the negative terminal.

Always replace O-rings and clamps with new ones.

Do not kink or twist tubes when they are being installed.

Do not tighten hose clamps excessively to avoid damaging hoses.

After connecting fuel tube quick connectors, make sure
quick connectors are secure.
Ensure that connector and resin tube do not contact any
adjacent parts.

After installing tubes, check if there are no fuel leaks at con-
nections in the following steps.
–Apply fuel pressure to fuel lines with turning ignition switch
“ON” (with engine stopped). Then check for fuel leaks at
connections.
–Start engine and rev it up and check for fuel leaks at con-
nections.

For servicing “Evaporative Emission System” parts, refer to
EC-522, "
EVAPORATIVE EMISSION SYSTEM" (WITH EURO-
ODB) or EC-962, "
EVAPORATIVE EMISSION SYSTEM"
(WITHOUT EURO-OBD).

WARNING:
Be sure to read “General Precautions” when working on the fuel system. Refer to FL-3, "
General Pre-
cautions" .
1. Check fuel level on fuel gauge. If gauge indicates more than the
level as shown in the figure (full or almost full), drain fuel from
fuel tank until gauge indicates level as shown in the figure or
below.
NOTE:
Fuel will be spilled when removing main and sub fuel level sen-
sor units for the top of the fuel is above the main and sub fuel
level sensor units installation surface.

As a guide, fuel level becomes the position as shown in the
figure or below when approximately 15 (3-1/4 Imp gal) of
fuel are drained from fuel tank.

In case fuel pump does not operate, perform the following
procedure.
a. Insert fuel tube of less than 25 mm (0.98 in) in diameter into fuel filler tube through fuel filler opening to
draw fuel from fuel filler tube.
b. Disconnect fuel filler hose from fuel filler tube. Refer to FL-11, "
FUEL TANK" .
c. Insert fuel tube into fuel tank through fuel filler hose to draw fuel from fuel tank.
2. Release the fuel pressure from the fuel lines. Refer to EC-49, "
FUEL PRESSURE RELEASE" (WITH
EURO-OBD) or EC-562, "
FUEL PRESSURE RELEASE" (WITHOUT EURO-OBD).
3. Open fuel filler lid.
4. Open fuel filler cap and release the pressure inside fuel tank.
5. Lift to hold rear seat cushion up. Refer to SE-32, "
REAR SEAT" .

level shown in figure (full or almost full), drain fuel from fuel tank
until gauge indicates level shown in figure or below.

Refer to the following for draining fuel.
a. Insert fuel tube of less than 25 mm (0.98 in) in diameter into fuel
filler tube through fuel filler opening to draw fuel from fuel filler
tube.
b. Disconnect fuel filler hose from fuel filler tube.
c. Insert fuel tube into fuel tank through fuel filler hose to draw fuel
from fuel tank.

As a guide, fuel level becomes the position shown in figure or
below when approximately 15 liter (3-1/4 lmp qt) of fuel are drained from full tank.
NOTE:
Adjusting fuel level is to prevent fuel from spilling, when fuel level sensor unit is removed.
