Fuel Pump Unit Removal/Installation
FUEL PUMP UNIT REMOVAL/INSTALLATIONWARNING: Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and damage. Fuel can also irritate skin and eyes. To prevent this, do not damage the sealing surface of the fuel pump unit when removing or installing.
CAUTION: Disconnecting/connecting the quick release connector without cleaning it may possibly 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.
1. Complete the "BEFORE REPAIR PROCEDURE". (See BEFORE REPAIR PROCEDURE.)
2. Disconnect the negative battery cable.
3. Remove the rear seat cushion.
4. Remove in the order indicated in the table.
5. Install in the reverse order of removal.
6. Complete the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE.)
Plastic Fuel Hose Removal Note
CAUTION: The quick release connector may be damaged if the tab is bent excessively. Do not expand the tab over the stopper.
1. Disconnect the quick release connector.
1. Push the tab on the locking coupler 90 ° until it stops.
2. Pull the fuel hose straight back.
NOTE:
- The stopper may be removed from the quick connector. Take care not to lose it Reinstall it to the quick release connector before reconnecting the fuel line.
- The locking coupler has two internal locking tabs which retain the fuel pipe. Be sure that the tab on the locking coupler is rotated until it stops to release two internal locking tabs.
2. Cover the disconnected quick release connector and fuel pipe with vinyl sheets or the like to prevent them from being scratched or contaminated with foreign material.
Fuel Pump Cap Removal Note
CAUTION: The cap could be damaged if the SST is used with any play 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 with two of the four brackets removed.
Fuel Pump Cap Installation Note
1. Align the fuel pump unit alignment marks and the floating lines as shown in the figure.
2. Align the tightening start positions of the fuel pump cap and the retainer notch as shown in the figure, and tighten them one full rotation by hand.
- If the fuel pump cap cannot be tighten by hand, remove the fuel pump cap, verify that there is no damage or misalignment on the retainer and fuel pump cap, and then tighten again.
CAUTION: The fuel pump cap could be damaged if the SST is used with any play between the fuel pump cap and the SST. Securely attach the SST so that there is no gap between the SST brackets and the side of the cap.
3. While keeping the alignment mark and the floating lines aligned, tighten the fuel pump cap to the rotation angle and specified torque using the SST.
- If the specified torque cannot be obtained even when the fuel pump cap is rotated to the specified rotation angle, replace with a new fuel pump cap and retainer and repeat Step 3.
Rotation angle: 50 - 140 °
(Total angle for Step 2 and Step 3 is 410 - 500 °.)
Cap tightening torque: 80 - 135 N.m {8.2 - 13.7 kgf.m, 59 - 99 ft.lbf}
Plastic Fuel Hose Installation Note
NOTE: A checker tab is integrated with quick release connector for new plastic fuel hoses. The checker tab will be released from the quick release connector after it is completely engaged with the fuel pipe.
1. Inspect the fuel pump unit sealing surface for damage and deformation, and replace if necessary.
- If the quick release connector O-ring is damaged, replace the plastic fuel hose.
2. Slightly apply clean engine oil to the sealing surface of the fuel pump unit.
3. Align the fuel pipe on the fuel pump unit and quick release connector so that the tabs of the retainer are correctly fitted into the quick release connector. Push the quick release connector straight into the retainer until a click is heard.
4. Lightly pull and push the quick release connector a few times by hand and verify that it can move 2.0 - 3.0 mm {0.08 - 0.11 in} and it is connected securely.
- If the quick release connector does not move at all, verify that O-ring is not damaged and slipped, and reconnect the quick release connector.
