Removal

CAUTION:  When repair to the fuel system has been 
completed, start engine  and check the fuel system 
for loose connections or leakage. For the fuel 
system diagnosis, see  Section “Driveability and 
Emission".

1. Disconnect battery ground cable.

2. Remove fuel filler cap.

3. Disconnect fuel hoses(1) from fuel filter on both 

engine side and fuel tank side.

4. Fuel filter fixing bolt.

• Remove the fuel filter fixing bolt on fuel filter 

holder(3).

5. Remove fuel filter(2).

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 and if it is clogged with dust, clean it 

out with air.

Installation

1. Install the fuel filter in the proper direction.

2. Install fuel filter holder fixing bolt.

3. Connect fuel hoses on engine side and fuel tank 

side.

4. Install fuel filler cap

5. Connect the battery ground cable.

Inspection

After installation, start engine and check for fuel leak 
age.

In–Tank Fuel Filter

The filter is located on the lower end of the 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 self cleaning 
type, not requiring scheduled maintenance. Excess 
water and sediment in the tank restricts fuel supply to 
the engine, resulting in engine stop. In such a case, the 
tank must be cleaned throughly.

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.

If the measure value is out of standard, conduct the 
pressure test.

Pressure test

For the pressure test to the fuel system, see Section 6E 
“Fuel Control System".
