Title: 2ZR-FXE (FUEL): FUEL PUMP (w/ Canister Pump Module): INSTALLATION; 2023 - 2025 MY Corolla Corolla HV [09/2022 -        ]

INSTALLATION

PROCEDURE

1. INSTALL FUEL SUCTION TUBE WITH PUMP AND GAUGE ASSEMBLY

(a) Install a new fuel suction tube set gasket to the fuel tank assembly.

(b) Set the fuel suction tube with pump and gauge assembly to the fuel tank assembly.

NOTICE:

  • Be careful not to bend the arm of the fuel sender gauge assembly.
  • Make sure the horizontal angle of the fuel suction plate sub-assembly is less than 90°.
  • To avoid applying excessive force to the tip of the fuel sender gauge assembly, tilt the fuel sub-tank sub-assembly diagonally and insert it into the fuel tank assembly as shown in the illustration.

2. INSTALL FUEL PUMP GAUGE RETAINER

(a) Install the fuel pump gauge retainer.

(1) While pressing down on the fuel suction tube with pump and gauge assembly, temporarily install the fuel pump gauge retainer.

(2) Temporarily install SST (plate) and SST (claw) to the fuel pump gauge retainer.

SST: 09808-01071

SST: 09808-14031

09808-01030

09808-01090

HINT:

Securely insert the ends of SST (claw) into the insertion points in the fuel pump gauge retainer.

(5) Using SST, rotate the fuel pump gauge retainer so that the triangle mark on the fuel pump gauge retainer is aligned with the triangle mark on the fuel tank assembly to install the fuel suction tube with pump and gauge assembly to the fuel tank assembly.

NOTICE:

  • Do not use any tools other than specified as this may result in damage to the fuel pump gauge retainer or fuel tank assembly.
  • Do not press down on SST excessively as this may make the fuel pump gauge retainer hard to rotate, and may damage components.
  • Make sure to rotate SST (handle) horizontally. If it is rotated at an angle, SST may come off.
  • Do not spin SST too fast or use an impact wrench as this may result in damage to components.
  • If SST comes off of the fuel pump gauge retainer, loosen SST (bolt) and reinstall SST.
  • Make sure that the fuel suction tube set gasket does not come off.

(b) Engage the claw to install the No. 1 fuel tube clamp.

3. INSTALL FUEL GAUGE WIRE (for 4WD)

(a) Engage the claw and install the fuel gauge wire to the fuel pump gauge retainer.

4. CONNECT FUEL TANK MAIN TUBE SUB-ASSEMBLY

(a) for 2WD:

Push the fuel tube joint onto the plug of the fuel suction plate sub-assembly, then install the tube joint clip.
