Removal and InstallationEBS00BLA
REMOVAL
1. Remove air duct, air cleaner case and mass air flow sensor assembly. Refer to EM-133, "AIR CLEANER
AND AIR DUCT" .
2. Remove fuel filter protector.
3. Disconnect fuel hoses at fuel filter bracket.
CAUTION:
Plug the pipe to prevent fuel from draining.
4. Remove fuel filter with fuel filter bracket.
CAUTION:
Do not splash fuel during removal. If fuel is splashed,
immediately wipe it off.
5. Using band-type fuel filter wrench (commercial service tool),
remove fuel filter.
6. Turn fuel filter upside down to drain fuel.
7. Remove drain plug from fuel filter.
INSTALLATION
Note the following, and install in the reverse order of removal.

Replace O-ring on drain plug with new one.

Screw the fuel filter by hand until packing contacts sealing surface of bracket. Then tighten it by turning
approximately 2/3 turn.

After installation, bleed air from fuel line. Refer to FL-18, "Air Bleeding" .
INSPECTION AFTER INSTALLATION
Make sure there is no fuel leakage at connections in the following steps.

Start the engine and rev it up and make sure there is no fuel leakage at connections.

FUEL FILTER

Air BleedingEBS00BLB
After fuel filter is replaced and after fuel system components are
removed/installed, bleed air from fuel line as follows:

Move priming pump up and down to bleed air from fuel path.

When air is bled, pumping of priming pump becomes heavy stop
operation at that time.

Crank engine until it starts. Do not crank engine for more than
30 seconds.

If engine does not start, stop cranking and repeat step 1 above.

If engine does not operate smoothly after it has started, race it
two or three times.

If air cannot be bled easily (pumping of priming pump does not
become heavy), disconnect feed-side of hose between fuel filter and electronically controlled fuel pump.
After that, operate priming pump and confirm that fuel comes out.
CAUTION:
Prepare a tray to collect fuel. Prevent fuel from adhering to rubber parts, especially the engine
mounting insulator.
Draining Water from Fuel FilterEBS00MRU
1. Prepare a tray at the drain hose open end.
2. Loosen drain cock, and operate priming pump to drain water
from fuel filter.
CAUTION:

Water in filter is drained with fuel. Prepare larger capacity
pan than fuel filter volume.

Drained water is mixed with fuel. Prevent fuel from adher-
ing to rubber parts such as engine mounting insulator.
3. After draining, close drain cock by hand.
CAUTION:
If drain cock is tightened excessively, it may be damaged
and fuel will leak. Do not use tools to tighten drain cock.
4. Bleed air in fuel piping. Refer to FL-18, "
Air Bleeding" .
5. Start engine and make sure there is no fuel leakage.

FUEL LEVEL SENSOR UNIT


Remove clip by turning it about 90 degrees clockwise.
7. Disconnect harness connector, fuel feed tube, fuel return tube
and fuel hose. (Figure shows left side of fuel tank.)

For the right, disconnect harness connector and fuel hose.

Disconnect quick connector of fuel feed tube and fuel return
tube as follows.
NOTE:

Hold the sides of the connector, push in tubs and pull out the
tube.

If the connector and the tube are stuck together, push and pull
several times until they start to move. Then disconnect them
by pulling.Left hand : Main fuel level sensor unit
Right hand : Sub fuel level sensor unit

FUEL LEVEL SENSOR UNIT

INSPECTION AFTER REMOVAL
Make sure 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.

Connect quick connector as follows.
1. Check connection for damage and foreign materials.
2. Align the connector with the tube, then insert connector straight into tube until a click is heard.
3. After connecting, make sure that the connection is secure by following the steps below.

Visually confirm that the two tabs are connected to connector.

Pull the tube and connector to make sure they are securely
connected.

Install fuel level sensor unit with mating mark (triangular pro-
trusion) facing between two carved lines on fuel tank. (Figure
shows left side of fuel tank.)
NOTE:
On right side of fuel tank, there are three carved lines on fuel
tank. Set mating mark between two outer carved lines.

Install inspection hole cover with the front mark (arrow) facing front of vehicle (both for RH and LH).
INSPECTION AFTER INSTALLATION
Make sure there is no fuel leakage at connections in the following steps.

Start engine and rev it up and make sure there is no fuel leakage at connections.
