id0114zc800900

Warning

•  Highly pressurized fuel may spray out if the fuel line is cut. Due to the following dangers occurring with a fuel spray, always complete the “Fuel Line Safety Procedure” to prevent the fuel from spraying.

―  Fuel may cause irritation if it comes in contact with skin and eyes.

―  If fuel ignites and causes a fire, it may lead to serious injury or death, and damage to property and facilities.

•  A person charged with static electricity could cause a fire or explosion, resulting in death or serious injury. Before draining fuel, make sure to discharge static electricity by touching the vehicle body.

Caution

•  Disconnecting/connecting the quick release connector without cleaning it may cause damage to the fuel pipe and quick release connector. Always clean the quick release connector joint area before disconnecting/connecting using a cloth or soft brush, and make sure that it is free of foreign material.

Fuel pump cap removal note

Caution

•  The fuel pump cap could be damaged if the SST is used with any gap between the cap and the SST. Securely attach the SST so that there is no gap between the SST tabs and the side of the cap.

1.  Remove the fuel pump cap using the SST.

Fuel pump cap installation note (packing part No. D350-*****)

Note

•  The fuel pump unit will rotate and cannot be secured in the specified position if there is any gasoline on the packing. Thoroughly wipe away all gasoline from the packing.

•  Make the markings to be easily visible when the fuel pump cap is installed.

•  Marks are provided on the fuel pump unit and fuel tank for correct installation of the fuel pump unit.

•  Tighten the fuel pump cap using a torque wrench to prevent fuel leakage.

1.  Mark the fuel pump cap and the fuel tank at the point where the threading of each part begins as shown in the figure.

am3zzw00017038

2.  Align the fuel tank alignment mark with the fuel pump unit as shown in the figure.

am3zzw00017039

3.  Align the fuel tank and fuel pump cap markings.

am3zzw00017040

4.  Rotate the fuel pump cap counterclockwise until the cap marking is approx. 15° away from the fuel tank marking as shown in the figure.

am3zzw00017041

5.  While keeping the fuel pump unit from rising up, tighten the fuel pump cap by hand 180 ° clockwise.

am3zzw00017042

Caution

•  The cap could be damaged if the SST is used with any play between the cap and the SST. Securely install the SST so that there is no gap between the SST tabs and the side of the cap.

6.  Set the SST as shown in the figure.

adejjw00015496

Note

•  The total rotation angle is 450—495 ° if the approx. 180° from Step 5 is included.

7.  Using a torque wrench, tighten the fuel pump cap with both of the following specified rotation angle and specified torque met being careful not to shift the marks on the fuel pump unit and fuel tank.

am3zzw00017043

Caution

•  To avoid exceeding the specified rotation angle due to excessive torque, tighten the fuel pump cap starting from the minimum value of 80 N·m {8.2 kgf·m, 60 ft·lbf} and gradually increase the tightening torque without exceeding the maximum value of 180 N·m {18 kgf·m, 132 ft·lbf}, and secure the specified rotation angle of 270—315°.

•  If the specified tightening torque cannot be obtained, replace the fuel pump cap and packing.

•  If the specified tightening torque cannot be obtained after replacement of the fuel pump cap and packing, replace the fuel tank.

Note

•  The total rotation angle is 450—495 ° if the approx.180 ° from Step 5 is included.
