Inspection

1. Replace the fuel filter if the fuel leaks from fuel filter

body or if the fuel filter body itself is damaged.

2. Replace the filter if it is clogged with dirt or sediment.
3. Check the drain of receive rubber and if it is clogged

with dust, clean it up with air.

Installation

2. Install fuel filter holder fixing bolt.
3. Connect fuel hoses on engine side(1) and fuel tank

side(2).

4. Install fuel filler cap
5. Connect the battery ground cable.

Inspection

After installation, start engine and check for fuel leakage.

In–Tank Fuel Filter

The filter is located on the lower end of fuel pickup tube in
the fuel tank. It prevents dirt from entering the fuel pipe
and also stops water unless the filter is completely
submerged in the water. It is a selfcleaning type, not
requiring scheduled maintenance. Excess water and
sediment in the tank restricts fuel supply to the engine,
resulting in engine stoppage. In such a case, the tank
must be cleaned thoroughly.

Fuel Pump Flow Test

If reduction of fuel supply is suspected, perform the
following checks.

1. Make sure that there is fuel in the tank.
2. With the engine running, check the fuel feed pipe and

hose from fuel tank to injector for evidence of
leakage. Retighten, if pipe or hose connection is
loose. Also, check pipes and hoses for squashing or
clogging.

3. Insert the hose from fuel feed pipe into a clean

container, and check for fuel pump flow rate.

4. Connect the pump relay terminals with a jumper

wire(1) as shown and start the fuel pump to measure
delivery.

CAUTION: Never generate sparks when connecting
a jumper wire.

fixing snap ring and remove the FPAS assembly.

NOTE: After removing pump assembly (4), cover fuel
tank to prevent any dust entering.

Installation

1. Install FPAS assembly(4).
2. Install Fuel Tube/Quick Connector (2).

NOTE: Handling of the fuel tube sure to refer “Fuel
Tube/Quick Connector Fittings” in this section.

Precautions

D

Lighting of Fires Prohibited.

D

Keep flames away from your work area to prevent the
inflammable from catching fire.

D

Disconnect the battery negative cable to prevent
shorting during work.

D

When welding or conducting other heat-generating
work on other parts, be sure to provide pretreatment
to protect the piping system from thermal damage or
spattering.

Cautions During Work

Do not expose the assembly to battery electrolyte or do
not wipe the assembly with a cloth used to wipe off spilt
battery electorolyte.
The piping wet with battery electrolyte cannot be used.
Be careful not to give a bending or twisting force to the
piping during the work. If deformed, replace with a new
piping.

Removal

1. Open the fuel cap to relieve the fuel pressure in the

tank.
If the fuel quick-connect fittings are dusty, clean with
an air blower, etc. and then remove it.

141RW036

As some pressure may remain in the piping, cover the
connector with a cloth, etc. to prevent the splashing
of fuel in the first disconnection of the piping.

2. For removal of the delivery pipe (feeding fuel to the

engine), and return pipe (returning fuel to the tank)
hold the connector in one hand, and hold the retainer
tab with the other hand and pull out the connector, as
illustrated. The pipe can be removed with the retainer
attached.

141RW019

NOTE: This work should be done by hands. Do not use
any tools. Should the pipe can hardly be removed from
the connector, use a lubricant (light oil) and/or push and
pull the connector longitudinally until the pipe is removed.
