Fuel Tank: Service Precautions

PRECAUTION

HINT: Any DTC retained by the computer will be erased when the negative (-) terminal cable is removed from the battery. Therefore, if necessary, read the diagnosis before removing the negative (-) terminal cable from the battery.

1. BEFORE WORKING ON FUEL SYSTEM, DISCONNECT NEGATIVE (-) TERMINAL CABLE FROM BATTERY
2. DO NOT SMOKE OR WORK NEAR AN OPEN FLAME WHEN WORKING ON THE FUEL SYSTEM
3. KEEP GASOLINE AWAY FROM RUBBER OR LEATHER PARTS

4. AIR INDUCTION SYSTEM
a. Separation of the engine oil dipstick, oil filler cap, PCV hose, etc. may cause the engine to run out of tune.
b. Disconnection, looseness or cracks in the parts of the air induction system between the throttle body and cylinder head will allow air suction and cause the engine to run out of tune.

5. FUEL SYSTEM




a. Quick Type B:
Observe these precautions when disconnecting the fuel tube connector:

1. Check that there is any dirt and/or mud in the pipe and around the connector before disconnecting them and clean the dirt away.
2. Be sure to disconnect them with hands.
3. When the connector and the pipe are stuck, push and pull the connector to free them. And then disconnect and pull it out. Do not use any tools at this time.
4. Inspect if there is any dirt or the like on the seal surface of the disconnected pipe and clean it away.
5. Prevent the disconnected pipe and connector from being damaged and foreign objects mixing in by covering them with a vinyl bag.




b. Quick Type B:
Observe these precautions when connecting the fuel tube connector:

1. Check that there is any damage or foreign objects in the connected part of the pipe.
2. Match the axis of the connector with the axis of the pipe, and push into the connector until the connector makes a "click" sound. In case that the connection is tight, apply little amount of fresh engine oil on the tip of the pipe.
3. After having finished the connection, check if the pipe and the connector are securely connected by pulling them.
4. Check that there is any fuel leak.




c. Observe these precautions when handling nylon tube.

1. Pay attention not to turn the connected part of the nylon tube and the quick connector by force when connecting them.
2. Pay attention not to kink the nylon tube.
3. Do not remove the EPDM protector from the outside of the nylon tube.
4. Must not close the piping with the nylon tube by bending it.




d. Check that there is any fuel leak after maintenance anywhere on the fuel system.

1. Connect a hand-held tester to the DLC3.
2. Turn the ignition switch ON, and push the hand-held tester main switch ON.

NOTE: Do not start the engine.

3. Select the ACTIVE TEST mode on the hand-held tester.
4. Please refer to the hand-held tester operator's manual for further details.




5. Pinch the fuel return hose.
The pressure in the high pressure line will rise to approx. 392 kPa (4 kgf/sq.cm, 57 psi). In this state, check to see that there are no leaks from any part of the fuel system.

NOTE: Always pinch the hose. Avoid bending as it may cause the hose to crack.

6. Turn the ignition switch OFF.
7. Disconnect the hand-held tester from the DLC3.
