PROCEDURE

1. INSTALL FUEL SUCTION WITH PUMP AND GAUGE TUBE ASSEMBLY

(a) Apply a light coat of gasoline to a new gasket, and install it to the fuel tank assembly.

(b) Align the protrusion of the fuel suction with pump and gauge tube assembly with the groove of the fuel tank assembly.

*a

(c) Install the fuel suction with pump and gauge tube into the fuel tank.

NOTICE:

Be careful not to bend the arm of the fuel sender gauge.

(d) Apply a co-rotation prevention check mark to the fuel suction with pump and gauge tube assembly.

HINT:

Perform this procedure when replacement of the fuel suction with pump and gauge tube assembly is necessary.

*a

Co-rotation Prevention Check Mark

(e) Temporarily place the fuel pump gauge retainer by aligning the rotational start point mark of a new fuel pump gauge retainer with the rotational start point mark of the fuel tank assembly while pressing the fuel suction with pump and gauge tube into the fuel tank assembly.

*a

(f) Set 4 SSTs (claw sets) to the fuel pump gauge retainer and temporarily install.

SST: 09808-14031

09808-01080

09808-01090

09808-01100

NOTICE:

  • Align the cutout of SST (claw set) to the rib of the fuel pump gauge retainer.
  • Do not place SST on the rotational start point mark of the fuel pump gauge retainer, otherwise SST (claw set) cannot be set correctly.

(k) While one person presses the fuel suction with pump and gauge tube assembly into the fuel tank assembly, have another person firmly press the fuel pump gauge retainer into the threads of the fuel tank assembly and tighten approximately one and a half turns.

NOTICE:

  • Do not use any tools other than SST, such as a screwdriver, etc.
  • Do not use excessive force when pressing down on SST, as the fuel suction with pump and gauge tube assembly will place excessive force on the pump gauge retainer and be difficult to remove, and parts may be damaged.
  • Do not use an impact wrench or turn the SST handle with excessive force, as parts may be damaged.
  • Do not rotate the fuel pump gauge retainer when the co-rotation prevention check mark is out of place.

(l) Check the tightening condition of the fuel pump gauge retainer.

(1) Using a vernier caliper, measure the upper surface dimensions of the fuel tank assembly at the 3 positions as shown in the illustration.

Standard:

Measurement difference is within 3 mm.

NOTICE:

If the measurement difference is approximately 6 mm, the threads misaligned by 1 threads (6 mm) and the fuel pump gauge retainer must be installed again.
