Fuel Pump Cap Installation Note

1. Align the convex of the fuel pump unit with the notch of the retainer as shown in the figure.
   NOTE:

   • Remove the residue of gasoline on gasket or cap completely. Any residue of gasoline can make the fuel pump unit turn round and prevent it from fixing.

2. Adjust the start mark of the fuel tank with the center one out of three rib lines of the cap, then turn it around 360°  degrees by hand as shown in the figure.
   • If the retainer and cap cannot be tighten by hand, remove the cap, verify that there is no damage or misalignment on the retainer and cap, and then tighten again.
   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.

3. While keeping the alignment mark and the retainer notch aligned, tighten the cap to the rotation angle and specified torque using the SST  .

• If the specified torque cannot be obtained even when the cap is rotated to the specified rotation angle, replace with a new cap and retainer and repeat Step 3.

Rotation angle (Total angle for Step 2 and Step 3) 

580-620° 

Cap tightening torque (approx.) 

80-180 N.m {8.2-18 kgf.m, 60-132 ft.lbf}
