(3) Connect SST (adapter and hose) to the
injector, and hold the injector and union with
SST (clamp).
SST 09268-31011 (09268-41110, 09268-
41130, 09268-41310)
(4) Put the injector into the graduated cylinder.
CAUTION:
Install a suitable vinyl tube onto the injector
to contain gasoline spray.
(5) Operate the fuel pump.
(6) Connect SST (wire) to the injector and the
battery for 15 seconds, and measure the
injection volume with the graduated cylinder.
Test each injector 2 or 3 times.
SST 09842-30080
Standard injection volume:
76 to 92 cm
3 (4.6 to 5.6 cu in.) per 15
seconds
Standard difference between each injector:
16 cm
3 (1.0 cu in.) or less
(c) Inspect the fuel leakage.
(1) Disconnect the SST (wire) tester probes from
the battery and check the fuel leakage from the
injector.
Standard fuel drop:
1 drop or less per 12 minutes
(2) Turn the ignition switch OFF.
(3) Disconnect the cable from the negative (-)
battery terminal.
(4) Remove SST.
SST 09842-30080
(5) Disconnect the intelligent tester from the DLC3.
(6) Reconnect the fuel inlet hose (rear fuel pipe) to
the fuel main tube.
INSTALLATION
1. INSTALL FUEL INJECTOR ASSEMBLY
(a) Apply a light coat of gasoline or spindle oil to new O-
rings, then install one onto each fuel injector.

REMOVAL
1. REMOVE FUEL TANK ASSEMBLY
(a) Remove the fuel tank (see page FU-39).
2. REMOVE FUEL TANK MAIN TUBE SUB-ASSEMBLY
(a) Remove the joint clip and fuel tank main tube.
CAUTION:
• Before removing the tube joint clip, check for
foreign matter around the clip. Clean if
necessary.
• Keep the O-ring free of foreign matter, as it
becomes contaminated easily.
• Do not use any tools in this procedure.
• Do not forcefully bend or twist the tube.
• Put the tube in a plastic bag to prevent
damage and contamination.
• If the fuel suction plate and tube are stuck
together, pinch the tube and turn it carefully
to disconnect it.
• Be careful not to damage the clip. If the clip is
damaged, replace it.
3. REMOVE FUEL TANK VENT TUBE SET PLATE
(a) Remove the 8 bolts and set plate.
4. REMOVE FUEL SUCTION WITH PUMP ASSEMBLY
(a) Disconnect the fuel hose and remove the fuel pump
from the fuel tank.
NOTICE:
Do not damage the fuel pump.
