(k) 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.

3 (3.4 ± 4.5 cu in.) per 15 sec.
Difference between each injector:

3 (0.8 cu in.) or less
If the injection volume is not as specified, replace the injector.
2. INSPECT LEAKAGE
(a) In the condition above, disconnect the test probes of SST
(wire) from the battery and check the fuel leakage from
the injector.
SST 09842±30070
Fuel drop: 1 drop or less per 12 minutes
(b) Turn the ignition switch OFF.
(c) Disconnect the negative (±) terminal cable from the bat-
tery.
(d) Remove the SST and fuel tube connector.
SST 09268±41047, 09842±30070
CAUTION:

Perform disconnecting operations of the fuel tube
connector (quick type) after observing the precau-
tions. (See page SF±1)

vent it from splashing inside the engine compart-
ment.
(e) Disconnect the TOYOTA hand±held tester from the

INSTALLATION
1. INSTALL INJECTORS AND DELIVERY PIPES
(a) Install new insulator and grommet to each injector.
(b) Apply a light coat of spindle oil or gasoline to 2 new O±
rings and install them to each injector.
(c) Apply a light coat of spindle oil or gasoline on the place
where a delivery pipe touches an O±ring of the injector.
(d) While turning the injector clockwise and counterclock-
wise, push it to the delivery pipes. Install the 6 injectors.
(e) Position the injector connector outward.
(f) Place the 4 spacers in position on the intake manifold.

(g) Apply a light coat of spindle oil or gasoline on the place
where a intake manifold touches an O±ring of the injector.
(h) Place the delivery pipes and fuel pipe together with the 6
injectors in position on the intake manifold.
(i) Temporarily install the 4 bolts holding the delivery pipes
to the intake manifold.
(j) Temporarily install the bolt holding the No.1 fuel pipe to
the intake manifold.
(k) Check that the injectors rotate smoothly.
HINT:
If injectors do not rotate smoothly, the probable cause is incor-
rect installation of O±rings. Replace the O±rings.
(l) Position the injector connector outward.
(m) Tighten the 4 bolts holding the delivery pipes to the intake
manifold.
Torque: 10 N´m (100 kgf´cm, 7 ft´lbf)
(n) Tighten the bolt holding the No.1 fuel pipe to the intake
manifold.
Torque: 19.5 N´m (200 kgf´cm, 14 ft´lbf)
2. CONNECT NO.1 FUEL PIPE
(a) Align the alignment marks (white paint) on the No.1 fuel
pipe.
(b) Connect the No.1 fuel pipe (fuel tube connector) to the
fuel filter.
CAUTION:
Perform connecting operations of the fuel tube connector
(quick type) after observing the precaution.

Heated Oxygen Sensor (Bank 1 Sensor 2)
Before installing the heated oxygen sensor,
twist the sensor wire counterclockwise
3 and 1/2 turns. HINT:
After installing the heated oxygen sensor,
check that the sensor wire is not twisted,
if it is twisted, remove the heated oxygen
sensor and reinstall it.

INSPECTION
INSPECT FUEL TANK AND LINE
(a) Check the fuel lines for cracks or leakage, and all connec-
tions for deformation.
(b) Check the fuel tank vapor vent system hoses and connec-
tions for looseness, sharp bends or damage.
(c) Check the fuel tank for deformation, cracks, fuel leakage
or tank band looseness.
(d) Check the filler neck for damage or fuel leakage.
(e) Hose and pipe connections are as shown in the illustra-
tion.
If a problem is found, repair or replace the parts as necessary.
