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 self cleaning 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.

Fuel Pump Relay

General Description

In order to control the FP operation, the FP relay is
provided. When the starter switch is turned to “ON”
position, the FP relay operates the FP for 2 seconds.

When it is turned to “START” position, the Power Train
Control Module (PCM) receives the reference pulse from
the Ignition Control Module and it operates the relay,
again causing the FP to feed fuel.
