CAUTION:
Keep the injector clean of sparks during the test.
(a)
Disconnect the fuel inlet hose (fuel tube connector) from
the fuel filter.
(b)
Connect SST (attachment and hose) to the fuel tube.
SST
09268–41047 (09268–52011)
(c)
Remove the pressure regulator from the delivery pipe.
(d)
Install the O–ring to the fuel inlet of the pressure regulator.
(e)
Connect SST (hose) to the fuel inlet of the pressure regu-
lator with SST (union) and the 2 bolts.
SST
09268–41047 (09268–41091)
Torque: 7.5 N·m (76 kgf·cm, 66 in.·lbf)
(f)
Connect the fuel return hose to the fuel outlet of the pres-
sure regulator.
(g)
Install the O–ring to the injector.
(h)

INJECTOR
2764
(o)
Connect SST (wire) to the injector and battery for 15 se-
conds, and measure the injection volume with a gra-
duated cylinder. Test each injector 2 or 3 times.
SST
09842–30070
Volume: 56 to 69 cm
3
(3.4 to 4.2 cu in.) per 15 seconds
Difference between each injector:
13 cm
3
(0.8 cu in.) or less
If the injection volume is not as specified, replace the injector.
2.
INSPECT LEAKAGE
(a)
Under the above conditions, disconnect the tester probes
of SST (wire) from the battery and check fuel leakage
from the injector.
SST
09842–30070
