INSTALLATION
1. Install new O-rings to the fuel supply pump housing.
2. Install fuel supply pump housing to the fuel supply pump.
●Using a hexagon -head wrench [face to face 5 mm (0.20 in)
SST], tighten the fuel supply pump housing mounting bolt.
3. Install coupling to the fuel supply pump.
●Using the TORX wrench (SST), tighten the sprocket nut to fix
the coupling.
4. Install adjusting shim.
●For shim adjustment, measure dimension L (Distance
between front surface of the coupling and the fuel supply
pump flange) at 2 opposing points near the coupling bolt cen-
ter. Use the average of these two measurements to select the
shim grade that marked on adjusting shim.
●The shim adjustment is required only when the fuel supply
pump is replaced.
