REMOVAL
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" .

6. Remove inspection hole cover for main and sub fuel level sen-
sor units by turning clips clockwise by 90 degrees.

Remove cover by pushing it, then by turning clips clockwise
by 90 degrees and by matching both cover hole and clip
shape.
7. Disconnect harness connector and fuel feed hose.

Disconnect quick connector as follows:
–Hold the sides of connector, push in tabs and pull out fuel feed
hose.
–If quick connector sticks to tube of fuel level sensor unit, push
and pull quick connector several times until it starts to move.
Then disconnect quick connector by pulling.

CAUTION:

Quick connector can be disconnected when the tabs
are completely depressed. Do not twist it more than
necessary.

Do not use any tools to disconnect quick connector.

Keep resin tube away from heat. Be especially careful
when welding near the resin tube.

Prevent acid liquid such as battery electrolyte, etc.
from getting on resin tube.

Do not bend or twist resin tube during installation and
disconnection.

Do not remove the remaining retainer on hard tube (or
the equivalent) except when resin tube or retainer is
replaced.

When resin tube or hard tube (or the equivalent) is
replaced, also replace retainer with a new one.

Replace same color retainer as before replacing.

To keep the connecting portion clean and to avoid
damage and foreign materials, cover them completely
with plastic bags or something similar.
8. Using a fuel tank lock ring wrench (commercial service tool),
remove lock ring.
9. Remove main fuel level sensor unit, fuel filter and fuel pump assembly, and sub fuel level sensor unit as
follows.
CAUTION:

Do not bend float arm during removal.

Avoid polluting the inside by residue fuel. Draw out with avoiding inclination by supporting with
a cloth.

Avoid impacts such as falling when handling components.Retainer color: Green

a. Removal of main fuel level sensor unit, fuel filter and fuel pump
assembly:
i. Raise main fuel level sensor unit, fuel filter and fuel pump
assembly, and disconnect jet pump.
ii. Leave jet pump on fuel tank with fuel hose.
CAUTION:
Do not disconnect jet pump and fuel hose.
iii. If necessary, remove chamber from the bottom of fuel tank by
sliding toward the rear of the vehicle.
b. Removal of sub fuel level sensor unit:
i. Raise and release sub fuel level sensor unit to remove.
ii. If necessary, remove jet pump inlet from the bottom of fuel tank by pinching tabs.
CAUTION:
Do not separate jet pump inlet and fuel hose.
INSPECTION AFTER REMOVAL
Make sure that fuel pump strainer is free from foreign materials. If any are found, remove them.
INSTALLATION
Note the following, and install in the reverse order of removal.
Chamber and Jet Pump
When installing chamber and jet pump, insert them fully until a click
sound of full stopper engagement is heard (Ditto for jet pump inlet).
Main and Sub Fuel Level Sensor Unit
1. Install seal packing to fuel tank without any twist.
2. Face fuel level sensor unit, fuel filter and fuel pump assembly as
shown in the figure, and install it to fuel tank. (Figure shows left
side of fuel tank.)
CAUTION:
Do not bend float arm during installing.
NOTE:
On right side of fuel tank, there are three carved lines on fuel
tank. Set mating mark between two outer carved lines.
3. Tighten rock ring with rock ring wrench (commercial service tool).
CAUTION:
Install rock ring horizontally.
Quick Connector
Connect quick connector as follows:
1. Check the connection for damage and foreign materials.
