ENGINE FUEL (6VD1 3.2L)
When reusing the delivery and return pipe retainer,
reuse without removing the retainer from the pipe. If
the retainer is damaged or deformed, however,
replace with a new retainer.
Cover the connectors removed with a plastic bag, etc.
to prevent the entry of dust or rain water.

Reuse of Quick–Connector
(Delivery Pipe and Return Pipe)
D
Replace the pipe and connector if scratch, dent or
crack is found.
D
Remove mud and dust from the pipe and make sure
that the end including spool is free of defects, such as
scratch, rust, and dent, which may cause poor
sealability. If defective, replace with a new pipe.
D
If the retainer removed according to the removal step
above is attached to the pipe, clean and insert it
straight into the quick-connector till it clicks. After it
clicks, try pulling it out to make sure that it is not drawn
and is securely locked.
NOTE: The retainer, once removed from the pipe, cannot
be reused. Just replace with a new retainer. Insert the
new retainer into the connector side until it clicks, and
connect the pipe as inserting it into the retainer until it
clicks.

Assembling Advice
Application of engine oil or light oil to the pipe facilitates
connecting work. The work should be started immediately
after lubrication, since dust may stick to the pipe surface
to cause poor sealability if a long time passes after
lubrication.
Test/Inspection After Assembling
1. Reconnect the battery negative cable.
2. Turn the ignition key to the “ON” position and check
pump startup sound. As the pump is actuated to raise
fuel pressure, check and see fuel leak from the piping
system.
3. Make sure of no fuel leakage by conducting the above
fuel leak check a few times.
4. Start the engine and make sure of stable idling speed
and normal vehicle run.The entry of dust during the
work may sometimes affect the fuel injection system.
Fuel Pump Relay
General Description
In order to control the FPAS operation, the FPAS relay is
provided. When the starter switch is turned to “ON”
position, the FPAS relay operates the FPAS for 2
seconds.
When it is turned to “START” position, the Engine Control
Module receives the reference pulse from the Ignition
Control Module and it operates the relay, again causing
the FPAS to feed fuel.
