REMOVAL
1. REMOVE AIR CLEANER HOSE
2. REMOVE AIR INTAKE CHAMBER ASSEMBLY
(See page EM±32)
3. DISCONNECT INJECTOR CONNECTORS
4. REMOVE AIR ASSIST HOSES AND PIPE
(a) Disconnect the air assist pipe from the bracket on the
No.1 fuel pipe.
(b) Remove the air assist hoses from the intake manifold.
5. DISCONNECT NO.1 FUEL PIPE
(a) Remove the fuel hose clamp.
(b) Disconnect the No.1 fuel pipe (fuel tube connector) from
the fuel filter outlet.
CAUTION:
Perform disconnecting operations of the fuel tube
connector (quick type) after observing the precau-
tions. (See page SF±1)
As there is retained pressure in the fuel pipe line, pre-
vent it from splashing inside the engine compart-
ment.

INSPECTION
1. INSPECT INJECTOR INJECTION
CAUTION:
Keep injector clear of sparks during the test.
(a) Purchase the new No.1 fuel pipe and take out the fuel
tube connector from its pipe.
Part No. 23801±20041
(b) Connect SST (hose ) and fuel tube connector to the fuel
filter outlet.
SST 09268±41047
CAUTION:
Preform connecting operations of the fuel tube connector
(quick type) after observing the precautions.
(See page SF±1)
HINT:
Use the vehicle fuel filter.

(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.
SST 09842±30070
Volume:
60 ± 73 cm
3 (3.4 ± 4.5 cu in.) per 15 sec.
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) 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)
As there is retained pressure in the fuel pipe line, pre-
vent it from splashing inside the engine compart-
ment.
(e) Disconnect the TOYOTA hand±held tester from the
DLC3.

(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.
