8. FUEL SYSTEM
(a) When disconnecting the high pressure fuel line, a large
amount of gasoline will spill out, so observe these proce-
dures:
(1) Disconnect the fuel pump connector.
(2) Start the engine. After the engine has stopped on
its own, turn the ignition switch OFF.
(3) Put a container under the connection.
(4) Slowly loosen the connection.
(5) Disconnect the connection.
(6) Plug the connection with a rubber plug.
(7) Reconnect the fuel pump connector.
(b) When connecting the flare nut or union bolt on the high
pressure pipe union, observe these procedures:
(1) Union Bolt Type:
Always use a new gasket.
(2) Union Bolt Type:
Tighten the union bolt by hand.
(3) Union Bolt Type:
Tighten the union bolt to the specified torque.
Torque: 29 N´m (300 kgf´cm, 22 ft´lbf)
(4) Flare Nut Type:
Apply a light coat of engine oil to the flare and tight-
en the flare nut by hand.
(5) Flare Nut Type:
Using SST, tighten the flare nut to the specified
torque.
SST 09631±22020
NOTICE:
Do not rotate the fuel pipe, when tightening the flare nut.
Torque:
30 N´m (310 kgf´cm, 22 ft´lbf) for using SST
38 N´m (387 kgf´cm, 28 ft´lbf)
HINT:
Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).

INSTALLATION
1. INSTALL INJECTORS AND DELIVERY PIPE
(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 pipe. Install the 6 injectors.
(e) Position the injector connector outward.
(f) Place the 3 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 6 injectors together with the delivery pipe and
3 bolts in position on the intake manifold.
(i) Temporarily install the 3 bolts holding the delivery pipe to
the intake manifold.
(j) 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.
(k) Position the injector connector upward.
(l) Connect the 6 injector connectors.
HINT:
The Nos.1, 3, 5 injector connectors and dark gray, and the
Nos.2, 4, 6 injector connectors are brown.
(m) Tighten the 3 bolts holding the delivery pipe to the intake
manifold.
Torque: 21 N´m (210 kgf´cm, 15 ft´lbf)
(n) Connect the camshaft position sensor connector.
(o) Connect the throttle position sensor connector.
(p) Connect the VSV connector for EVAP.
2. INSTALL FUEL PRESSURE PULSATION DAMPER
(See page SF±27)
3. INSTALL AIR INTAKE CHAMBER
(See page SF±49)
4. INSTALL ENGINE COVER
Install the engine cover with the 4 nuts.
